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.
