3.2 Principle of operation

The VEGAPULS 61 is a radar sensor for continuous level measure­ment of liquids under simple process conditions.

Dependent on the application range, dierent versions are used:

Level measurement of aggressive liquids in small vessels: encap-

•

sulated antenna system

Flow measurement in open umes or gauge measurement of bod-

•

ies of water: Plastic horn antenna
Products with an εr value ≥ 1.8: Standard electronics

•

Products with an εr value ≥ 1.5, < 1.8; applications with very poor

•

reective properties: Electronics with increased sensitivity

The actual values that can be reached depend on the measurement
conditions, the antenna system or the standpipe or bypass.

Functional principle

Packaging

36501-EN-121011

VEGAPULS 61 • Probus PA

The antenna of the radar sensor emits short radar pulses with a
duration of approx. 1 ns. These pulses are reected by the product
and received by the antenna as echoes. The transit time of the radar
pulses from emission to reception is proportional to the distance and
hence to the level. The determined level is converted into an appropri­ate output signal and outputted as measured value.

3.3 Packaging, transport and storage

Your instrument was protected by packaging during transport. Its
capacity to handle normal loads during transport is assured by a test
according to DIN EN 24180.

4.1 General instructions

With instruments with threaded process tting, suitable tools must be
applied for tightening the hexagon.

Warning:

The housing must not be used to screw the instrument in! Applying
tightening force can damage internal parts of the housing.

Moisture

Suitability for the process
conditions

Use the recommended cables (see chapter "Connecting to power
supply") and tighten the cable gland.

You can give your instrument additional protection against moisture
penetration by leading the connection cable downward in front of the
cable entry. Rain and condensation water can thus drain o. This ap­plies mainly to outdoor mounting as well as installation in areas where
high humidity is expected (e.g. through cleaning processes) or on
cooled or heated vessels.

Make sure that all parts of the instrument exposed to the process, in
particular the active measuring component, process seal and process
tting, are suitable for the existing process conditions. These include
above all the process pressure, process temperature as well as the
chemical properties of the medium.

You can nd the specications in chapter "Technical data" and on the
type label.

4.2 Collaroradapterange

For mounting the instrument on a socket, a combi compression ange
for DN 80 (ASME 3" or JIS 80) is also available for retro tting. Option­ally, the instrument can be also equipped with an adapter ange from
DN 100 (ASME 4" or JIS 100).

With the housing versions plastic, aluminium single chamber and
stainless steel, the collar ange can be placed directly over the hous­ing. With the aluminium double chamber housing, retroactive mount­ing in this way is not possible - the mounting type must be specied
with the order.

You can nd drawings of these mounting options in chapter "Dimen-
sions".

Fig. 5: Flange mounting of the radar sensor

4.3 Mounting preparations, mounting strap

The mounting strap enables simple mounting on the vessel wall or
silo top. It is suitable for wall, ceiling or boom mounting. Especially in
open vessels this is a very easy and eective way to align the sensor
to the bulk solid surface.

The strap is supplied unassembled and must be screwed to the
sensor before setup with three hexagon screws M5 x 10 and spring
washers. Max. torque, see chapter "Technical data". Required tools:
Allen wrench size 4.

There are two ways to screw the strap onto the sensor. Depending
on the selected version, the sensors can be swivelled in the strap as
follows:

Single chamber housing

•

– Angle of inclination 180°, innitely variable
– Angle of inclination in three steps 0°, 90° and 180°

Double chamber housing

•

– Angle of inclination 90°, innitely variable
– Angle of inclination in two steps 0° and 90°

4.4 Instructions for installation

For tight installation of the version with plastic horn antenna with com­pression or adapter ange, the following conditions must be fullled:

1. Use suitable at seal, e.g. of EPDM with Shore hardness 25 or 50

2. Make sure the number of ange screws corresponds to the num­ber of ange holes

3. Tighten all screws with the torque stated in the technical data

Polarisation plane

Installation position

16

The emitted radar impulses of the radar sensor are electromagnetic
waves. The polarisation plane is the direction of the electrical wave
component. By turning the instrument in the connection ange or
mounting boss, the polarisation can be used to reduce the eects of
false echoes.

The position of the polarisation plane is marked on the process tting
of the instrument.

When mounting the sensor, keep a distance of at least 200 mm
(7.874 in) to the vessel wall. If the sensor is installed in the center of

dished or round vessel tops, multiple echoes can arise. These can,
however, be suppressed by an appropriate adjustment (see chapter
"Setup").

If you cannot keep this distance you should carry out a false echo
storage before setup. This applies mainly if buildup on the vessel wall
is expected. In this case, we recommend repeating a false echo stor­age later with existing buildup.

Fig. 9: Mounting of the radar sensor on round vessel tops

In vessels with conical bottom it can be advantageous to mount the
sensor in the center of the vessel, as measurement is then possible
down to the lowest point of the vessel bottom.

A corresponding collar ange for DN 80 (ASME 3" or JIS 80) as well
as a suitable adapter ange are available for mounting VEGAPULS

61.

With the housing versions plastic, aluminium single chamber and
stainless steel, the collar ange can be placed directly over the hous­ing. With the aluminium double chamber housing, retroactive mount­ing in this way is not possible - the mounting type must be specied
with the order.

Information:

The socket should be as short as possible and the socket end
rounded. Thus, false reections by the vessel socket are reduced.

Fig. 12: Recommended socket mounting

If the medium has good reective properties, VEGAPULS 61 can
also be mounted on a longer socket piece. Recommended values
for socket heights are specied in the following illustration. You must
carry out a false echo storage afterwards.

Make sure when planning your measuring site that the radar sensor
has a "clear view" to the measured product.

In case of existing vessel installations, a false echo storage should be
carried out during setup.

If large vessel installations such as struts or supports cause false
echoes, these can be attenuated through supplementary measures.
Small, inclined sheet metal baes above the installations scatter the
radar signals and prevent direct interfering reections.

Fig.18:Coversmoothproleswithdeectors

Agitators

Foam generation

If there are agitators in the vessel, a false signal memory should be
carried out with the agitators in motion. This ensures that the interfer­ing reections from the agitators are saved with the blades in dierent
positions.

Fig. 19: Agitators

Through the action of lling, stirring and other processes in the vessel,
compact foams that considerably damp the emitted signals may form
on the product surface.

If foams are causing measurement errors, the biggest possible radar
antennas, the electronics with increased sensitivity or low frequency
radar sensors (C band) should be used.

As an alternative, sensors with guided microwave can be used. These
are unaected by foam generation and are best suited for such ap­plications.

Measurement in a surge
pipe

When using a surge pipe in a vessel, inuences from vessel installa­tions and turbulences can be excluded. Under these prerequisites,
the measurement of products with low dielectric values (εr value
≥ 1.6) is possible. In very adhesive products, measurement in a surge
pipe is not recommended.

Always keep in mind the following safety instructions:

Connect only in the complete absence of line voltage

•

If overvoltage surges are expected, overvoltage arresters should

•

be installed

Voltage supply

Connection cable

Cable gland ½ NPT

Cable screening and
grounding

36501-EN-121011

VEGAPULS 61 • Probus PA

The voltage supply is provided by a Probus DP /PA segment coupler.
The voltage supply range can dier depending on the instrument

version. You can nd the data for voltage supply in chapter "Technical
data".

Connection is made with screened cable according to the Probus
specication. Power supply and digital bus signal are carried over the
same two-wire connection cable.

Use cable with round cross-section. A cable outer diameter of
5 … 9 mm (0.2 … 0.35 in) ensures the seal eect of the cable gland.
If you are using cable with a dierent diameter or cross-section,
exchange the seal or use a suitable cable gland.

Please make sure that your installation is carried out according to the
Probus specication. In particular, make sure that the termination of
the bus is done with appropriate terminating resistors.

You can nd detailed information of the cable specication, installa­tion and topology in the "ProbusPA-UserandInstallationGuide-
line" on www.probus.com.

With plastic housing, the NPT cable gland or the Conduit steel tube
must be screwed without grease into the threaded insert.

Max. torque for all housings see chapter "Technical data"

Make sure that the cable screening and ground is executed accord­ing to the Fielbus specication. If electromagnetic interference is
expected which is above the test values of EN 61326-1 for industrial
areas, we recommend to connect the cable screen on both ends to
ground potential.

With systems with potential equalisation, connect the cable screen
directly to ground potential at the power supply unit, in the connection
box and at the sensor. The screen in the sensor must be connected
directly to the internal ground terminal. The ground terminal outside
on the housing must be connected to the potential equalisation (low
impedance).

In systems without potential equalisation with cable screening on
both sides, connect the cable screen directly to ground potential at
the power supply unit and at the sensor. In the connection box or
T-distributor, the screen of the short stub to the sensor must not be
connected to ground potential or to another cable screen. The cable
screens to the power supply unit and to the next distributor must be
connected to each other and also connected to ground potential via a

Connection technology

ceramic capacitor (e.g. 1 nF, 1500 V). Low-frequency potential equali­sation currents are thus suppressed, but the protective eect against
high frequency interference signals remains.

5.2 Connecting

The voltage supply and signal output are connected via the spring­loaded terminals in the housing.

The connection to the indicating and adjustment module or to the
interface adapter is carried out via contact pins in the housing.

Information:

The terminal block is pluggable and can be removed from the elec­tronics. To do this, lift the terminal block with a small screwdriver and
pull it out. When inserting the terminal block again, you should hear it
snap in.

Connection procedure

Proceed as follows:

1. Unscrew the housing cover

2. If an indicating and adjustment module is installed, remove it by
turning it slightly to the left.

3. Loosen compression nut of the cable entry

4. Remove approx. 10 cm (4 in) of the cable mantle, strip approx.
1 cm (0.4 in) of insulation from the ends of the individual wires

5. Insert the cable into the sensor through the cable entry

Fig. 24: Connection steps 5 and 6

6. Insert the wire ends into the terminals according to the wiring plan

Information:

Solid cores as well as exible cores with cable end sleeves are
inserted directly into the terminal openings. In case of exible cores
without end sleeves, press the terminal head with a small screwdriver;
the terminal opening is freed. When the screwdriver is released, the
terminal closes again.

7. Check the hold of the wires in the terminals by lightly pulling on

them

8. Connect the screen to the internal ground terminal, connect the
outer ground terminal to potential equalisation

9. Tighten the compression nut of the cable entry. The seal ring must
completely encircle the cable

10. Place probably existing indicating and adjustment module back

on

11. Screw the housing cover back on

The electrical connection is hence nished.

5.7 Set instrument address

An address must be assigned to each Probus PA instrument. The
approved addresses are between 0 and 126. Each address must
only be assigned once in the Probus PA network. The sensor is only
recognized by the control system if the address is set correctly.

When the instrument is shipped, address 126 is adjusted. This ad­dress can be used for function test of the instrument and for con­nection to a Probus PA network. Then address must be changed to
integrate additional instruments.

The address setting is carried out either via:

The address selection switch in the electronics compartment of

•

the instrument (address setting via hardware)
The indicating and adjustment module (address setting via soft-

•

ware)
PACTware/DTM (address setting via software)

•

Hardware addressing

32

The hardware addressing is eective if an address <126 is adjusted
with the address selection switches on the instrument. Hence the
software addressing is no longer eective, the adjusted hardware
address is valid.

5.8 Switch-on phase

After VEGAPULS 61 is connected to the bus system, the instrument
carries out a self-test for approx. 30 seconds. The following steps are
carried out:

Internal check of the electronics

•

Indication of the instrument type, hardware and software version,

•

measurement loop name on the display or PC
Indication of the status message "F 105 Determine measured

•

value" on the display or PC
Status byte goes briey to fault value

•

As soon as a plausible measured value is found, it is outputted to the
signal cable. The value corresponds to the actual level as well as the
settings already carried out, e.g. factory settings.

6.3 Parameter adjustment

Through the parameter adjustment the instrument is adapted to the
application conditions. The parameter adjustment is carried out via an
adjustment menu.

The main menu is divided into ve sections with the following func-

tions:

Setup: Settings, for example, to measurement loop name, medium,
application, vessel, adjustment, AI FB 1 Channel - scaling - damping

Display: Language setting, settings for the measured value indication
as well as lighting

Diagnosis: Information, for example on the instrument status, pointer,
reliability, AI FB 1 simulation, echo curve

Further settings: Instrument units, false signal suppression, lineari­zation, sensor address, PIN, date/time, reset, copy sensor data

Info: Instrument name, hardware and software version, calibration
date, instrument features

In the main menu point "Setup", the individual submenu points should
be selected subsequently and provided with the correct parameters
to ensure the optimum adjustment of the measurement. The proce­dure is described in the following.

36501-EN-121011

Setup/Medium

tion. With bulk solids, these are dust generation, material cone and
additional echoes from the vessel wall.

To adapt the sensor to these dierent measuring conditions, the
selection "Liquid" or "Bulk solid" should be made in this menu item.

Through this selection, the sensor is adapted perfectly to the product
and measurement reliability, particularly in products with poor reec­tive properties, is considerably increased.

Enter the requested parameters via the appropriate keys, save your
settings with [OK] and jump to the next menu item with the [ESC] and
the [->] key.

Setup/Application

36501-EN-121011

VEGAPULS 61 • Probus PA

In addition to the medium, also the application, i.e. the measuring site,
can inuence the measurement.

With this menu item, the sensor can be adapted to the applications.
The adjustment possibilities depend on the selection "Liquid" or "Bulk
solid" under "Medium".

The following options are available when "Liquid" is selected:

Caution:

If a separation of liquids with dierent dielectric gure occurs in the
vessel, for example through condensation, the radar sensor can
detect under certain circumstances only the medium with the higher
dielectric gure. Keep in mind that layer interfaces can cause faulty
measurements.

If you want to measure the total height of both liquids reliably, please
contact our service department or use an instrument specially de­signed for interface measurement.

If these values are not known, an adjustment with the distances of for
example 10 % and 90 % is possible. Starting point for these distance
specications is always the seal surface of the thread or ange. By
means of these settings, the real level will be calculated.

The respective min. and max. measured value is saved in the sensor.
The values are displayed in the menu item "Peak values".

When non-contact level sensors are used, the measurement can be
inuenced by the respective process conditions. In this menu item,
the measurement reliability of the level echo is displayed as dB value.
The measurement reliability equals signal strength minus noise. The
higher the value, the more reliable the measurement. With a function­ing measurement, the values are > 10 dB.

The "Echo curve" shows the signal strength of the echoes over the
measuring range in dB. The signal strength enables an evaluation of
the quality of the measurement.

The "False signal suppression" displays the saved false echoes (see
menu "Additional settings") of the empty vessel with signal strength in
"dB" over the measuring range.

False signal suppression

The following circumstances cause interfering reections and can
inuence the measurement:

High sockets

•

Vessel installations such as struts

•

Agitators

•

Buildup or welded joints on vessel walls

•

Note:

A false signal suppression detects, marks and saves these false sig­nals so that they are no longer taken into account for level measure­ment.

This should be done with the low level so that all potential interfering
reections can be detected.

Proceed as follows:

1. Select the menu item "Additional settins" with [->] and conrm
with [OK]. With [->] you have to select the menu item "False

6 Set up with the indicating and adjustment module

Note:

Check the distance to the product surface, because if an incorrect
(too large) value is entered, the existing level will be saved as false
signal. The lling level would then no longer be detectable in this area.

If a false signal suppression has already been created in the sensor,
the following menu window appears when selecting "False signal
suppression":

The menu item "Delete" is used to completely delete an already cre­ated false signal suppression. This is useful if the saved false signal
suppression no longer matches the metrological conditions in the
vessel.

The menu item "Extend" is used to extend an already created false
signal suppression. This is useful if a false signal suppression was
carried out with a too high level and not all false signals could be de­tected. When selecting "Extend", the distance to the product surface
of the created false signal suppression is displayed. This value can
now be changed and the false signal suppression can be extended to
this range.

Additional adjustments/
Linearization curve

46

A linearization is necessary for all vessels in which the vessel volume
does not increase linearly with the level - e.g. in a horizontal cylindri­cal or spherical tank - and the indication or output of the volume is
required. Corresponding linearization curves are preprogrammed
for these vessels. They represent the correlation between the level
percentage and vessel volume.

By activating the appropriate curve, the volume percentage of the
vessel is displayed correctly. If the volume should not be displayed in
percent but e.g. in l or kg, a scaling can be also set in the menu item
"Display".

Enter the requested parameters via the appropriate keys, save your
settings and jump to the next menu item with the [ESC] and [->] key.

Caution:

Note the following if the instrument with corresponding approval is
used as part of an overll protection system according to WHG:

If a linearisation curve is selected, the measuring signal is no longer
linearly proportional to the level. This must be taken into consideration

6.4 Saving the parameter adjustment data

We recommended noting the adjusted data, e.g. in this operating
instructions manual, and archiving them afterwards. They are thus
available for multiple use or service purposes.

If the instrument is equipped with an indicating and adjustment
module, the data in the sensor can be saved in the indicating and
adjustment module. The procedure is described in the operating
instructions manual "Indicating and adjustment module" in the menu
item "Copy sensor data". The data remain there permanently even if
the sensor power supply fails.

Information:

The interface adapter VEGACONNECT 3 is not suitable for connec­tion to the sensor.

7.2 Parameter adjustment with PACTware

For parameter adjustment of the sensor via a Windows PC, the con­guration software PACTware and a suitable instrument driver (DTM)
according to FDT standard are required. The up-to-date PACTware
version as well as all available DTMs are compiled in a DTM Collec­tion. The DTMs can also be integrated into other frame applications
according to FDT standard.

Note:

To ensure that all instrument functions are supported, you should
always use the latest DTM Collection. Furthermore, not all described
functions are included in older rmware versions. You can download
the latest instrument software from our homepage. A description of
the update procedure is also available in the Internet.

Further setup steps are described in the operating instructions manu­al "DTM Collection/PACTware" attached to each DTM Collection and
which can also be downloaded from the Internet. Detailed descrip­tions are available in the online help of PACTware and the DTMs.

Standard/Full version

All device DTMs are available as a free-of-charge standard version
and as a full version that must be purchased. In the standard version,
all functions for complete setup are already included. An assistant for
simple project conguration simplies the adjustment considerably.
Saving/printing the project as well as import/export functions are also
part of the standard version.

In the full version there is also an extended print function for complete
project documentation as well as a save function for measured value
and echo curves. In addition, there is a tank calculation program as
well as a multiviewer for display and analysis of the saved measured
value and echo curves.

The standard version is available as a download under www.vega.
com/downloads and "Software". The full version is available on CD
from the agency serving you.

7.3 Saving the parameter adjustment data

We recommend documenting or saving the parameter adjustment
data via PACTware. That way the data are available for multiple use or

9.1 Maintenance

If the device is used correctly, no maintenance is required in normal
operation.

9.2 Measured value and event memory

The instrument has several memories which are available for diagno­sis purposes. The data remain even with voltage interruption.

Measured value memory

Event memory

Echo curve memory

Up to 60,000 measured values can be stored in the sensor in a ring
memory. Each entry contains date/time as well as the respective
measured value. Storable values are for example:

Distance

•

Filling height

•

Percentage value

•

Lin. percent

•

Scaled

•

Current value

•

Meas. reliability

•

Electronics temperature

•

When the instrument is shipped, the measured value memory is
active and stores distance, measurement certainty and electronics
temperature every 3 minutes.

The requested values and recording conditions are set via a PC with
PACTware/DTM or the control system with EDD. Data are thus read
out and also reset.

Up to 500 events are automatically stored with a time stamp in the
sensor (non-deletable). Each entry contains date/time, event type,
event description and value. Event types are for example:

Modication of a parameter

•

Switching on and o times

•

Status messages (according to NE 107)

•

Error messages (according to NE 107)

•

The data are read out via a PC with PACTware/DTM or the control
system with EDD.

The echo curves are stored with date and time and the corresponding
echo data. The memory is divided into two sections:

Echo curve of the setup: This is used as reference echo curve for
the measurement conditions during setup. Changes in the measure­ment conditions during operation or buildup on the sensor can thus
be recognized. The echo curve of the setup is stored via:

9.3 Asset Management function

The instrument features self-monitoring and diagnostics according
to NE 107 and VDI/VDE 2650. In addition to the status messages in
the following tables there are more detailed error messages available
under the menu item "Diagnostics" via the indicating and adjustment
module, PACTware/DTM and EDD.

Status messages

The status messages are classied in the following categories:

Failure

•

Function check

•

Out of specication

•

Maintenance requirement

•

and explained by pictographs:

3 Outofspecication-yellow

4 Maintenance - blue

Failure: Due to a malfunction in the instrument, a failure message is
outputted.

This status message is always active. It cannot be deactivated by the
user.

Function check: The instrument is in operation, the measured value
is temporarily invalid (for example during simulation).

This status message is inactive by default. It can be activated by the
user via PACTware/DTM or EDD.

Outofspecication: The measured value is unstable because the
instrument specication is exceeded (e.g. electronics temperature).

This status message is inactive by default. It can be activated by the
user via PACTware/DTM or EDD.

Maintenance: Due to external inuences, the instrument function
is limited. The measurement is aected, but the measured value is
still valid. Plan in maintenance for the instrument because a failure is
expected in the near future (e.g. due to buildup).

This status message is inactive by default. It can be activated by the
user via PACTware/DTM or EDD.

Treatment of measure­ment errors with liquids

The below tables show typical examples of application-related meas­urement errors with liquids. The measurement errors are dierentiated
according to the following:

Constant level

also be the fault setting of the current output to "Hold value"
In case of a too low level indication, the reason could be a line

•

resistance that is too high

Approvals

Instruments with approvals can have dierent technical data depending on the version.
For that reason the associated approval documents of these instruments must be carefully noted.

They are part of the delivery or can be downloaded under www.vega.com and "VEGA Tools" as
well as under "Downloads" and "Approvals".

11.2 CommunicationProbusPA

11.2 Instrumentmasterle

The instrument master le (GSD) contains the characteristic data of the Probus PA instrument.
These data are, e.g. the permissible transmission rates as well as information on diagnostics values
and the format of the measured value outputted by the PA instrument.

A bitmap le is also provided for the Probus network planning tool. This le is installed automati­cally when the GSD le is integrated. The bitmap le is used for symbolic indication of the PA instru­ment in the conguration tool.

11.3 ID number

Each Probus instrument gets an unambiguous ident number (ID number) from the Probus user
organisation (PNO). This ID number is also included in the name of the GSD le. Optionally to this
manufacturer-specic GSD le, PNO provides also a general so-called prole-specic GSD le. If
the general GSD le is used, the sensor must be set to the prole-specic ident number via the DTM
software. By default, the sensor operates with the manufacturer-specic ID number. When using the
instruments on a segment coupler SK-2 or SK-3, no special GSD les are required.

The following table shows the instrument ID and the GSD names for the VEGAPULS radar sensors.

– This module must be used if a value in the data telegram of the cyclical data trac should not

be used (e.g. replacement of temperature and Additional Cyclic Value)

A maximum of three modules can be active. By means of the conguration software of the Probus
master you can determine the conguration of the cyclical data telegram with these modules. The
procedure depends on the respective conguration software.

Note:

The modules are available in two versions:

Status Value (IEEE-754)

Fig. 59: Data format of the output signal

The status byte corresponds to prole 3.02 "Probus PA Prole for Process Control Devices" coded.
The status "Measured value OK" is coded as 80 (hex) (Bit7 = 1, Bit6 … 0 = 0).

The measured value is transferred as a 32 bit oating point number in the IEEE-754 format.
