1 General Safety Instructions

• Select the appropriate pressure transmitter with regard to scale range,
performance and specific measurement conditions prior to installing and

Warnin

starting the instrument.

• Observe the relevant national regulations (e.g.: EN 50178, NEC, CEC)
and observe the applicable standards and directives for special
applications (e.g. with dangerous media such as oxygen, acetylene,
flammable gases or liquids and toxic gases or liquids and with
refrigeration plants or compressors).

If you do not observe the appropriate regulations, serious injuries
and/or damage can occur!

• Open pressure connections only after the system is without
pressure!

• Please make sure that the pressure transmitter is only used within the
overload threshold limit at all times!

• Observe the ambient and working conditions outlined in chapter 6
"Technical Data"

• Ensure that the pressure transmitter is only operated in accordance with
the provisions, i.e. as described in the following instructions.

• Do not interfere with or change the pressure transmitter in any other way
than described in these operating instructions...

• Remove the pressure transmitter from service and mark it to prevent it
from being used again accidentally, if it becomes damaged or unsafe for
operation..

• Take precautions with regard to remaining media in removed

pressure transmitter. Remaining media in the prsesure port may
be hazardous or toxic!

• Have repairs performed by the manufacturer only.

• Consider the details given in the EC-type examination certificate as well
as the respective specifications for explosion hazard use of the country
concerned (e.g.: IEC 60079, NEC, CEC). If you do not observe these
stipulations, serious injuries and/or damage can occur.

Other important safety guidelines can be found in the different sections of
this instruction manual.

Special Intrinsic Safety Instructions

2 Special Intrinsic Safety Instructions

2.1 Protection of diaphragm

As soon as the diaphragm of an instrument gets damaged, absolutely no intrinsic
safety can be guaranteed any longer! Thus the diaphragm must not come in con­tact with abrasive substances! The diaphragm must be protected against pressure

Warning

peaks and must not be touched by tools! Information about material consistency
against corrosion and diffusion can be found in our WIKA Handbook, 'Pressure and
Temperature Measurement' (German: ISBN 3-9804074-0-3, English: ISBN 3­9804074-1-1).

2.2 Special wiring advice

The housing must always be connected to earth to protect the instrument against
electromagnetic fields and electrostatic charges.

Warning

The cables and wires must not be damaged.
Cables for applications in Zone 1 and 2 or Zone 21 and 22 must be checked with
a test voltage between conductor/earth, conductor/screen, screen/earth of more
than 500 V (AC).
Flying leads with fine wires must be covered by an end splice (cable preparation).
Both the internal capacity and inductivity must be considered.
Conductive screens may only be connected to earth one-sided and outside the
hazardous area.

2.3 Connection to Zone 0

(In general Zone 0 is given when the instrument is surrounded by a mixture of
explosive gases more than 1.000 hours per year = continuous hazard. The trans-

Warning

mitter may only be operated under Zone 0 conditions, as long as an atmospherical
pressure of 0.8 to 1.1 bar is guaranteed).
The circuits must be of type Ex ia.
The ingress protection must comply to IP 67 according to IEC 529.

2.4 Special precaution for connection to Zone 0 and or Zone 20

Make absolutely sure to follow the advice given in the IEC publication 60 529 for
connection to Zone 0 and/or Zone 20 for IP 67 pressure connections!

Warning

Warning

Installation in non-metallic vessels:
All metallic parts reaching into Zone 0 and/or Zone 20 must be grounded.
The intrinsically safe circuit must be decoupled from the regular circuit.

If the mounting position is less than 1m away from the transition into Zone 0 and/or
Zone 20 an overvoltage protection must be integrated. This can either be done
within the transmitter (option: overvoltage protection), or outside the transmitter by
the customer himself.

Special Intrinsic Safety Instructions

2.5 Instructions for temperature ranges

Observe the permissible surface temperatures applicable for this range according
to the defined temperature classes.

Warning

Warning

Observe the maximum temperature value (of the temperature range defined under
item 15.3. in the EC type test certificate at the hexagon of the process connection.

Protect the pressure transmitter against touching or affix a warning notice.

Insulate heat sources thermally from the pressure transmitter (e.g. pipes or tanks).

2.6 Special instructions for dust explosion protection

Ensure that under hazardous dust environments the pressure transmitter is moun­ted in a shielded section and protect it against shocks.

Warning

Warning

When installing the pressure transmitter or the cable gland into areas which require
category 1D equipment, ensure that ingress protection IP 6X according to IEC 60
529 is guaranteed.

Observe the EN 50281-1-2 in relation to e.g. dust deposits and temperature.

The permissible ambient temperatures as well as the maximum surface tempera­tures are to be taken from the EC type test certificate.

Universal IS Pressure Transmitter UniTrans

Product Description

5 Product Description

The intrinsically safe pressure transmitter UniTrans can be used in level control
applications as well as for pressure measurement applications in process industry.
A variety of process connections, measurement ranges, main boards and display
options result in a product for a wide range of applications.

5.1 Construction

The UniTrans consists of a pressure sensor, a control interface unit and a housing
cover with optional display. Due to this modular design, different transmitter versions
can be mounted (see “Model Key” on page 151).

Direct Mounted

Processing Unit Housing

5.1.1 Pressure Transducer

The pressure transducer has a piezo-resistive or thinfilm measurement cell depend­ing on the pressure range. The sensors are temperature compensated, and have a
hermetically welded membrane which is "helium" leak-tested. The pressure transduc­ers do not have internal sealing elements.

Pressure transducers further distinguish themselves from one another based on their
pressure ranges and the different materials of wetted parts. Different process connec­tions can be selected to serve a wide range of applications.

Never exceed the overpressure limit of the respective pressure transducer.

Product Description

5.1.2 Processing Unit

The processing unit, which is integrated in the housing contains the terminal compart­ment and the keypad used for programming the transmitter. The four keys must be
activated (unlocked) before use. During normal operation the keypad is locked to pro­tect data and functions previously entered. The keypad is automatically locked when
no key is hit for 10 minutes. The processing unit converts the digitalized signal from
the measuring unit into a standard 4...20 mA current signal.

5.1.3 Display Unit

CALIBRATION
RANGE

The measured-value indicator has four digits (in a 7-segment display) + symbols. Be­low it, is line 1 (16-segment display) used to display error codes and the signal’s unit
of measure. The unit of measure can be selected by the operator. Measurements
over 9999 can not be correctly displayed. Please note this when choosing the unit
(e.g. 9999 Pascal = 0,09999 bar). Additional information is displayed in lines 2 and 3
(16-segment display). The operator can enter commands in the programming mode
on the display unit by means of menu guided, clear-text prompts.

Product Description

Transmitters with displays offer a larger number of programming and processing op­tions. These options include alarm status, damping, signal inversion, tank lineariza­tion and diagnostic messages.

Display units can be easily upgraded (see chapter 7.2).

5.2 Function

The pressure transducer converts the existing pressure into an electrical signal. Mi­croelectronics further process the input signal and produce a proportional 4-20 mA
standard signal.

The display-version allows programming (parameterization) and the display of ex­tended functions such as inversion, damping, alarm status and linearization.

5.2.1 Functions of Transmitters without Displays

• Calibration of zero and span under pressure (see 8.3)

Universal IS Pressure Transmitter UniTrans

Product Description

5.3 Installation Examples

The UniTrans is primarily used to monitor the pressure in pipes, technical equipment
and tanks. Depending on the pressure range pressures between 20 mbar up to 4000
bar can be measured. The pressure is measured using absolute (against a vacuum)
or relative (against external or air pressure) measurement depending on the type of
sensor selected.

The UniTrans is also used for hydrostatic pressure measurement within liquid filled
pipes and containers.

Operation of Devices without Displays

8 Operation of Devices without Displays

8.1 Preparation

This unit can be programmed before or after installation.

• Connect an ampere meter to the device’s output (between terminals I and L+).

• Note that after each action, a brief oscillation/deflection of 20 mA occurs (verifica­tion of a successful action).

The following functions can be programmed without a display unit:

• Zero point adjustment with a full or empty container (with/without pressure)

• Span adjustment with a full or empty container (with/without pressure)

• Integration time

• Mounting correction of the sensor (beginning with software version 1.05)

• Reset to manufacturer’s defaults

An error signal is caused by a current surge (21 mA or 3.6 mA; 5 sec) when
the zero point or span setting fall outside of the sensor’s nominal pressure
range during adjustments with existing pressure. No values are stored.
The keypad becomes inactive after 10 min. of disuse. All settings will de­fault to previously stored values. Only settings that have been confirmed
with the "OK" function are stored.

Calibration Value

Calibration of span

A change in the zero point has no effect on the calibrated span.
However, if the span end-point is higher than the peak value of the sen­sor’s nominal pressure range, then span end-point is fixed at this peak val­ue and the span is reduced accordingly.
A change in the span setting has no effect on the zero point. The zero point
and span end-point must fall within the sensor’s nominal pressure range.
A mounting correction must not be carried out when making an adjustment
with pressure (wet adjustment). Otherwise, the mounting correction must
be carried out before saving the zero point and the end value of span.

8.4 Calibration without Pressure

Determine the current reference values for the zero point and the span to be entered
in the transmitter before calibration. This is done as follows:

8.4.1 Zero Point Calibration

• Determine the hydrostatic pressure of the liquid’s surface that meets the zero point.

• Adjust this pressure in proportion to the sensor’s nominal pressure range.

• Multiply this proportion by 16 mA and add 4 mA to the result.

This produces the calculated current (value I
and used to programm the zero point (0%).

Example:

A pressure transducer with 0 ... 400 mbar (nominal pressure) needs to be pro­grammed.The liquid’s surface (with a density of 1) is 1 m above the diaphragm at the
zero point producing a pressure of 100 mbar.

10.2.4 Submenu 'Parameter' - Calibration

Calibration with pressure:

The calibration with pressure is only possible when the cyclic measurement is activated.

Set zero:

Before starting the calibration make sure that the pressure applied to the transmitter
has the value you want to set as zero point (P 0 %).

Set span:

Make sure that the pressure applied to the transmitter has the value you want to set
as upper end of span (P 100 %). The measuring range between zero point and upper
end of span will be saved as span.

In general the preset span is not affected when the zero point is changed. When,
however, the zero point is increased in a way that the upper end of span would reach
beyond the maximum nominal pressure of the transmitter, this maximum nominal
pressure value is defined as new upper end of span and the span is reduced
respectively. A modification of the span settings does not affect the zero point.

During a calibration under pressure two pressure values are set respectively for zero
and upper end point of span. These values, which must lie within the nominal
pressure range of the transmitter are respectively assigned to an output current
signal. When the applied pressure lies beyond the nominal pressure range of the
transmitter an error message is displayed. In this case the value is not saved.

Cyclic measurement (measured value):

The actual measured value for the calibration under pressure is displayed
(automatic actualisation).

Calibration without pressure:

Zero:

• Here a pressure value within the nominal pressure range of the transmitter must be
entered.

Span:

• Here a pressure value for the span within the nominal pressure range of the trans-

mitter must be entered.

When calibrating without pressure (dry calibration), a sensor mounting
correction should be carried out before or after the calibration (see also
chapter 10.2.7 ). For this, the sensor must be placed in the reference
position for the measurement (mounting position) and must not be
under pressure.
When calibrating with pressure (wet calibration), the mounting correc­tion is unnecessary, or it must be carried out before the zero point and
end of span are saved.

Nominal pressure range:

Here the sensor’s pressure range is displayed

Here the range of output current is set.

• 3.8 ... 20.5 mA
When the applied pressure rises beyond the nominal range the current value ends
at the set limit value.

• 4 ... 20 mA
When the applied pressure rises beyond the nominal range and the alarm goes off
a reset must be carried out, or the power supply must be cut
(see also chapter 10.2.7).

13.3 Warranty Conditions

The pressure transmitter has a 24 month warranty in accordance with the WIKA
General Terms of Delivery.

Repairs may only be carried out by the manufacturer. All other repairs and
device modifications are unauthorized and will void the warranty.

Warning

13.4 Glossary

Adjustment Allocation of the signal output range (4 ... 20 mA) to the desired

pressure measurement range or level measurement range.

Integration Also damping: timely communication of the measurement

signal; rise time of the current output signal after a signal surge

Inversion Conversion of the output signal from 4 ... 20 mA to 20 ... 4 mA

Nom. press. range The operating pressure range for which the sensor is designed

Zero point Start of the pressure measurement range

Parameterization Also configuration: programming of the relevant parameters

and the pressure measurement range specific to the application
and measurement location.

Span The programmed pressure measurement range

Span end point The highest pressure value of the programmed measurement

span (end-point of the span)

Tank linearization Determination of approximate volume/pressure ratio values

with non-linear correlations based on varying container designs

For example, a non-linear correlation exists between the filling
level and the volume in spherical containers.
During linearization, the non-linear volume is assigned the
4 ... 20 mA output signal from a table of values (proximity
process by means of up to 32 support points).

Defaults The sensor parameters are programmed by the manufacturer
