1 System description

1.1 Properties and fields of use

INFRA radiation sensors from the R 3XX series are robust, stationary
measuring sensors that are used in connection with indicating devices,
controllers or recording instruments for contact-free temperature
measurement and temperature monitoring, control or registration.

They enable you to record surface temperatures quickly and reliably even in
situations where traditional contact-based measurement is very difficult, is
only possible to a limited extent or is not actually possible at all. For
instance, they can be used on moving objects, materials with a poor thermal
conductivity, plastic materials and aggressive substances, small components
with a low thermal capacity, current-carrying elements and rails.

The radiation sensor collects the thermal radiation emitted from the
measurement object and uses a lens to concentrate it on the internal
infrared sensor. An optical filter restricts the sensor’s spectral region.

The IR sensor transforms the collected heat energy into an electric signal,
which is then processed in a microprocessor and converted into a linear
current output of 4...20 mA. The influence of the ambient temperature on the
measuring cell and electronics is compensated.

Sensors from the R3XX series are designed using the two-wire technique.
They therefore allow measured values to be transmitted so as to be immune
to interference – even over long distances – and make wiring particularly
simple. Interfering measured value peaks that occur in quick succession can
be suppressed by a variable attenuator.

The size of the measuring field recorded depends on the optics of the sensor
concerned and on the distance between the sensor and the measurement
object (see measuring field diagrams). It is possible to set the emission
factor (which is important for the radiation measurement), the transmission
factor and other parameters.

An interface with a HART® protocol is used to transmit the measured values
from the sensor and to transmit program information to the sensor.

Thanks to the features mentioned, measurement sensors from the R3XX
series can also be used in places where other measuring systems fail due to
unfavourable ambient conditions. Examples include:
Thermoforming machines for plastics
Extruders for plastics
Calendering lines for plastic films
Coating machines
Glassworking
Metalworking
Monitoring of goods in transit on conveyor belts
Monitoring of plant overheating

1.2 Sensor versions

The radiation sensors are delivered both in a compact form, with a built-in
measuring amplifier (Thermophil® INFRAsmart), and in a two-part form, with
a small radiation sensor and a separate measuring amplifier (Thermophil®
INFRAht). In this case, the radiation sensors and measuring amplifiers are
connected using a heat-resistant cable. The measuring amplifiers available
are types TR 40-10 (in a die-cast aluminium housing) and TR 41-10 (in a
plastic housing, with a display and keypad).

In order to protect the sensor against dust, vapours and other environmental
influences, its measurement opening is sealed with a solid disc or lens. It
can be cleaned without difficulty if it is steamed up or damaged. In the case
of a highly polluted atmosphere it is a good idea to use an air nozzle (see
accessories), which will largely keep the measurement opening clear by
continuously cleaning the air. For the event that the sensor is used at fairly
high ambient temperatures, special cooling jackets with a cooling water
connection are available.

Operating Instructions Radiation sensors R3XX

2 Safety precautions

The equipment is produced in line with the regulations currently in force and
only leaves the factory following thorough safety tests to ensure that it is in
perfect condition. Please follow the instructions provided with regard to
installing and operating the equipment.

2.1 General information

 Please read the operating instructions prior to installing and starting up

the equipment. Should you have any questions or difficulties, please
contact our service staff.

 Provide your operating and maintenance staff with detailed instructions

and provide them with all the information they need.

 The equipment’s internal self-monitoring systems and fault reports do

not replace the safety facilities in the overall system into which the unit is
integrated.

 Make sure that all regulations relating to the operation of your system

are observed.

 The equipment must be installed and maintained by qualified technical

personnel.

 Make sure that the data and operating conditions specified by BARTEC

are observed.

 For the utilisation of the IR protection window ZnSe, please observe the

safety instructions under chapter 3.3.2.

2.2 Installation location

 When installing the equipment, make sure that you observe the

permissible climatic and temperature conditions in line with the technical
data.

 If exceptional conditions exist at the installation location, suitable

measures must be taken to protect the equipment (cover, cooling,
heating). Please also look at the accessories we offer with respect to
this.

 Install the equipment in a location that is not subject to vibrations.
 Do not choose a location near any equipment that generates

electromagnetic fields (transformers, motors, power lines, magnets,
semiconductor actuators, high-frequency generators and the like).

 The sensors should be installed in a separate location to protective

circuits wherever possible.

 If, due to the local circumstances, inductive consumers such as

contactors or solenoid valves are installed nearby, interference in the
contactor coil should be suppressed using an RC circuit. Usually, the
manufacturers of this equipment offer appropriate suppressor
accessories.

Safety precautions
10

Operating Instructions Radiation sensors R3XX

2.3 Electrical connection

 Before connecting the equipment, check whether the rated voltage

specified on the rating plate corresponds to that available at the
installation location.

 The wiring must be carried out by trained specialists.
 Lay sensor and signal lines at a sufficient distance from live lines, in

separate cable ducts wherever possible.

2.4 Operating the equipment

 Before switching on the auxiliary power, make sure that the permissible

operating voltage for the equipment is not exceeded.

 For the power supply, use only a direct current voltage source with a

residual ripple below a maximum of 150 mV rms.

 It is important that the sensing head does not exceed the permissible

operating temperature during operation.

 During measurement operation, make sure that the radiation entrance

point is kept clear. The solid disc or the lens must not be clouded by
splashed water or condensed water and must not have any deposits of
dirt.

 In the event of faults, first determine whether you can rectify them

yourself. If this is not possible, switch off the equipment and send it to
BARTEC for repair, together with a precise specification of the fault.

 If you discover any signs of damage or destruction to any parts of the

equipment or if safe operation of the equipment cannot be guaranteed
for any other reason, do not start up the equipment or, if already in
operation, shut it down immediately. Notify the local service centre.
Make sure that the equipment cannot be switched on again until the
damage has been remedied.

 Contact our service specialists if you discover any faults or defects

during operation or if you have cause to doubt whether the equipment is
working properly.

3 Installation

3.1 Installation location

 The ambient conditions at the installation location must be within the

permissible temperature and climate ranges. The corresponding data
can be found in Section 1.4 Technical data.

 The installation location should be free from vibrations and free of

electromagnetic interference fields. Please also refer to the notes in
Section 2 with respect to this.

 When choosing an installation location, please make sure that the

permissible operating temperature for the particular sensor (Sensor
housing temperature) is adhered to (see 1.4).

 In the case of a fairly high ambient

temperature, position the sensor in such a
way that it is not exposed to heat
convection from the measurement object
(example 1).

 If such an arrangement is not possible, the sensor must be operated

with an additional cooling jacket (example 2). The cooling jackets are
fitted with a mounting flange (see accessories).

In order to prevent inadmissible heating or damage to the sensor in the
event that the supply of cooling water is cut off, it is also necessary to
monitor the water circulation. BARTEC offers suitable flow control
instruments.

Note:

The Thermophil® INFRAht radiation sensors must be positioned in such a
way that the cable between the radiation sensor and measuring amplifier is
not moved during measurement.

3.2 Measurement distance

The laws of optics must be taken into account when measuring radiation.
Depending on the distance between the radiation sensors and the
measurement object there will be certain minimum measuring field
diameters – see distance ratio (technical data).
The sensor type that is needed in each case, with the appropriate focal
length, must be determined in accordance with the required measuring field
size at the measurement object and the possible measurement distance. In
order to avoid incorrect measurements, the measurement object must fill the
entire field of view of the sensor lens. The lens field of view must therefore
be no larger than the measurement object itself.

The temperature of a plastic plate with the dimensions 220 x 400 mm is to
be measured using a Type R 300 radiation sensor.
At what distance must the sensor be mounted?

The smallest edge of the plastic plate measures 220 mm in length. For a
measuring field diameter of 220 mm, the measuring field diagram for Type R
300 sensors (see also 1.4.1) gives rise to a measurement distance of
approximately 380 mm.
Therefore, the distance between the sensor and the measurement object
should be no more than 380 mm.

3.3.1 Safety instructions for the operation of
Laserpointer type R300-101

To operate the Laserpointer type R300-101, please keep in mind the
following instructions:

The beam emitted by this LASER is strongly bundled.

Caution:

Do not look into the laser beam or at direct reflexes of reflecting or polished
surfaces - not even by means of optical instruments.

The working area has to be protected by suitable protective shields which
prevent the laser beam from leaving the protected area in an uncontrolled
way.

After the laser beam has crossed the setting range, it has to be blocked and
absorbed by means of a suitable shield.
Do NOT lead the laser beam at eye level.

Attach LASER warning signs at clearly visible locations next to all accesses
to the laser working area.

Caution:

Use of laser protective goggles is mandatory if you work with an open laser
beam.
The device should only be operated by persons who know these safety
instructions and are familiar with complying to them.

3.3.2 Safety instructions for the utilisation of
the IR protection window Zn-Se type
R300-136 (order no. 301954)

For the utilisation of the IR protection window ZnSe, observe the following
basic instructions:

 The IR protection window contains zinc selenide (ZnSe).
 Avoid any damage to the protection window.
 Damaged filters can cause dust formation. Inhaling or swallowing dust or

splints can cause intoxication. Call a doctor in case of emergency.

 For removing broken protection windows, wear gloves and in urgent

cases a respiratory protection mask and protection goggles.

 Wear gloves to clean the window.
 The protection window should only be replaced by persons familiar with

the safety instructions and observing them.

4.1 Measurement operation

Once the auxiliary power has been switched on, measurement operation can
be commenced.
Further operation depends on what the sensors are being used for. Please
consult the operating instructions for the connected equipment (e.g. display,
recording instruments, controllers).

Please heed the following during measurement operation:
 The sensor’s measurement opening must be clean. Dust deposits or

moisture may falsify the measured values and must therefore be
removed.

 Precision specifications are only valid for the measurement range

specified on the sensor.

 The radiation sensors must not be subjected to any radiation that is far

above the largest measurement range value for the series in question
(approximately 30 %). It is important that the radiation sensor does not
exceed the permissible operating temperature.

 Please also heed the safety precautions in Section 2.

Error messages

The following error messages can be displayed:

Above upper measurement range limit (“Messbereichsüberschreitung”)

This message is displayed if the value exceeds the preset measurement
range by more than 1 %.

(measurement range = upper range limit – lower range limit)

Below lower measurement range limit (”Messbereichsunterschreitung”)

This message is displayed if the value falls short of the preset measurement
range by more than 1 %.

(measurement range = upper range limit – lower range limit)

4.2 Configuration

Under various operating conditions it is necessary to select or change
certain settings. Configuration is carried out using an interface with a HART®
protocol.
A HART® programming device or a suitable PC software solution needs to
be used in order to change parameters. The HART® commands are
described in Section 7.
Sensors R 310, R 311, R 312 and R 320 can also be configured using
measured value transmitter TR 41-10.

Cleaning kit type R300-128 for pyrometers

BARTEC pyrometers are very durable and almost maintenance-free.
Maintenance is restricted to checking and cleaning the optics. If it is cleaned
regularly and carefully, the high reliability of the measuring system can be
preserved and guaranteed.
Arranged in a stable and convenient carrying case, the cleaning kit contains
all facilities to carry out the cleaning quickly and thoroughly and without any
risk for the process and the sensor.
If required, the components contained in the kit can be re-ordered
individually.

Use the vacuum brush to remove
loose dirt and dust particles. Dust that
is raised can be sucked off by means
of the rubber bellows.

Use the bellows to remove dirt
particles even from areas of the optics
that are difficult to access for the
brush.
To access deeper areas, you can
attach an extension nozzle.

Maintenance

Operating Instructions Radiation sensors R3XX

The air stream can be emitted either
continuously or as a strong air blast. Change the
position of the air outlet nozzle accordingly.

Use the cleaning spray if there are deposits
or hard-sticking dirt particles.
Let the fluid take effect for a short time.

With a cleaning tissue and by applying only
little pressure, carefully wipe off the dissolved
dirt.

Attention:

Never wipe across the lens before solid particles have been removed or
dissolved.

Attention:

For the utilisation of the IR protection window ZnSe, please observe the

8 Additional instructions for

use in dust-explosive areas

This supplementary chapter provides additional instructions for the safe
usage of

 Thermophil INFRAsmart type R300 / R301 / R302 and
 Thermophil



INFRAht Typ R310 / R311 / R312 / R320 with measuring

amplifier TR40-10

in potentially explosive areas.

General information

Installation

2), 3)

 The following details on the type plate have to meet the requirements of

the Ex field of application on site: device group, category, temperature
class, maximum surface temperature
(II 2 G Ex ib IIC T6…T4, II 2 D Ex ib IIC T

100

105°C / 160°C)

 Make sure there is no potentially explosive atmosphere during

installation.

 Installation and start-up may only be carried out by an appropriately

qualified electrician. The electrical connection is carried out via the
respective cable or the respective connection assembly. For
Thermophil INFRAsmart with connection via plug, only use the
appropriate connectors or connection cables which guarantee a
protection type of at least IP 64 (see “accessories”). The connectors
have to be mounted correctly.

 The intrinsically safe cables and wires leading to the device and

between the measuring head and the measuring amplifier have to be
designated as intrinsically safe. This can be done by means of an
appropriate label or by a light-blue wrapping.

 Check the compatibility of the housing sealing materials to the mediums

existing at the place of application by taking into consideration the
ambient temperature (see resistance).

 Do not open the housing with the exception of the measurement

amplifier type TR40-10!

 Avoid or, if this is not possible, safely discharge any electrostatic

charges. It may be necessary to earth the metallic housing and any
parts in the environment. If a purge air facility is used at the optical
system, pay attention to the risk of a separation of charges caused by
flowing air polluted by dust.

 Caution! Before working with circuits and before opening the connection

assembly within a potentially explosive area, switch off the power supply
of the circuits. Within a potentially explosive area, only the tools and
measurement equipment approved for this purpose may be used.

Maintenance

 Dust deposits should be restricted or completely prevented if possible. In

order to prevent any unusual temperature rise at the dust-proof housing
caused by excessive dust deposits, clean the housing regularly.

Safety instructions

 Potentially explosive areas are defined under atmospheric conditions

within a temperature range from –20°C to +60°C and a pressure range
between 0.8 bar and 1.1 bar. Any operation outside these limits may
result in additional restrictions.

 Make sure that any potential dust deposits do not exceed a maximum

thickness of 100 mm.

Resistance

The following plastic materials are used as sealing materials for the housing:

 polybutylenterephthalate (PBT)4)
 viton (O-rings)

Before the application, the operator has to check the resistance of these
plastic materials to the mediums existing at the place of application by also
taking into consideration the climatic ambient conditions at the place of
application (temperature, humidity..).

Emission factor

If you want to measure the temperature of an object without contact, you

need to know the emission degree “E” and include it in the measurements.

The calibration basis for IR temperature measuring units and control units is
the black body with the emission degree E = 1.

Determining the actual E factor

The emission factor depends on the material and the condition of its surface.
Theoretical values are specified in the corresponding literature.
Due to the fact that the E factor also depends on the wavelength, the
temperature and the direction in which the radiation is emitted, however, the
values listed in the table can only be used as rough approximates, for
instance for project planning. It can generally be said that raw, matt or
oxidized surfaces have a higher E factor than shiny materials.

In practice, it is a good idea to verify the E factor once by taking a
comparison measurement. Various measurement procedures may be
suitable depending on the circumstances.

Drill hole method:
A hole with a depth of 2 - 3 mm is drilled into the measurement object and
an immersion measurement is taken in the hole using a low-mass sensor
(semiconductor or thermal element,  0.5 mm). Then, the temperature is
measured using a radiation sensor and the E factor is adjusted until the “true
temperature” determined beforehand is displayed.

Emission conversion:
The surface of the measurement object is covered with a substance for
which the E factor is known (e.g. black 3M "Velvet Coating 2010" matt
varnish; E 0.93).

You can also apply this method if you want to measure the surface
temperature of shiny rollers (E 0.2). Usually, it is possible to apply the
adhesive matt varnish at the edge of this isothermally heated calendar.

If this is not possible, or if the temperature distribution across the roller
length is irregular, you should use what is called an emission converter, like
the one shown in the picture. In the process, a thin black Teflon strip (E

0.95) stretched on a frame makes contact with the roller and is measured
using the radiation sensor.

Taking a measurement on a slow-running roller with the aid of the emission
converter:

Contact-based measurement:
Measure the surface temperature of the measurement object, for instance
using a low-mass thermal spiral or band element. This method cannot be
used for substances with a very poor thermal conductivity, though.

Convection measurement:
If it is not possible to take a contact-based measurement because the
measurement object is moving extremely quickly (as may be the case for a
calendar or roller, for instance), a roller sensor that works based on the
convection principle can be used. The large time constant of the sensor
must be taken into account but it does not interfere with this one-off
measurement.

Test method:
If you blacken part of a material sample (e.g. with Velvet Coating from 3M)
and then, for instance, heat it up in a climatic test cabinet, you can take a
differential measurement to establish the exact value of the emission factor.
In other words, with the E factor set to 1, you take a measurement on the
blackened part and then take a measurement on the part that has not been
blackened. By changing the E factor, you set the same display as before and
can now read the E factor on the E regulator.

Transmission factor

The transmission factor specifies the percentage of radiation that passes an
additional protective window.
If you do not have the details of the transmission factor for the protective
window used, you can work it out yourself.

Determining the transmission factor

 Measure the temperature of the measurement object with the

sensing head, without using the protective window. When you do
this, make sure that the correct emission factor is set.

 In the configuration, enter 1.000 as the transmission factor (see

page 35 Transmission factor).

 Use the protective window.
 Change the transmission factor in the configuration and repeat the

measurement. Compare the measured temperature with the
temperature that was measured without the protective window.

 Keep repeating this process until the temperature displayed is the

same as that for the measurement without the protective window.
