Field of application
CombiTemp™ TFRx is a temperature sensor, based on RTD technology, which is designed and produced to meet the requirements in food & beverage and pharmaceutical industry where hygienic connections are used.
CombiTemp™ TFRx comprises a series of basic elements which can be combined in various ways to a CombiTemp TFRx temperature sensor.
The product offers great flexibility in respect to modification, service and maintenance.
The sensor can be made to feature a RTD output signal or with a built in FlexTop™ temperature transmitter types 2202, 2211, 2212, 2221 and 2222 with 4-20 mA output (for documentation of FlexTops, please see relevant data sheet or operating instructions).
This instrument is constructed and tested according to the current EU directives and packed in technically safe condition. In order to maintain this condition and to ensure safe operation, the user must follow the instructions and warnings given in this manual.
During the installation local standards have to be observed. Ignoring the warnings may lead to severe personal injury or substantial damage to property.
The product must be operated by trained staff. Correct and safe operation of this equipment is dependent on proper transport, storage, installation and
operation.
All electrical wiring must conform to local standards and the connection must be made according to the connecting diagrams. Before switching on power supply take care that there is no unwanted interaction with other equipment. Ensure that the supply voltage and the conditions in the environment comply with the specification of the device.

Check the maximum temperature for the cable used Be sure to fixate the instrument before tightening the cable gland. When using M16 stainless steel and M20 stainless steel the maximum tightening torque is 4 Nm.
When upgrading the TFRx without display with a DFON touch screen, remember to remove the O-ring from the sealing. Otherwise the sealing won’t be tight.
Mounting for TFRN
The CombiTemp™ TFRN can be mounted in several different ways.
- Sensor tube without connection
Baumer offers compression glands fitting Ø6 and Ø8 mm sensor diameter. This type of mounting is normally used for mounting a sensor direct into a non-pressurized application. If pressurized, ensure that the connection is tightened correctly, so no leakage occur.
A duct channel mounting flange for 8 mm sensor is also available.
All threaded connections can be mounted directly into the application without thermowell, however often a thermowell is required to enable the user to take out the sensor for e.g. calibration without opening the system.
- Sensor with male threaded process connection G 1/2 A This is suitable in a Baumer thermowell type ZPT4. The process connections available for ZPT4 are R 1/2, G 1/2 A, G 3/4 A, M20 or with hygienic ISO 2852 clamp DN 38.
- Sensor with male threaded process connection G 3/4 A and G 1 A and sensors with G 1/2 or G 3/4 female thread can be supplied with a special thermowell. Please contact Baumer.
Mount the gland/pocket into the application and install the sensor after the gland/pocket is fixed to the application.
This will ensure that the cable is not twisted during mounting.
Baumer recommends to use a thermal compound filled into the thermowell to ensure best possible heat transfer between the pocket and the CombiTemp TFRN. Baumer offers a 6 gram bag Thermal compound, type ZPX1-001
Mounting for TFRH
Installation of 3-A and EHEDG-approved products:
Generally for welding adapters in a tank
- Use only a 3-A/EHEDG-approved counterpart.
- Level the inner surface of the tank with the welding adapter.
- If it is possible, always face the inspection hole downwards, so a leaking gasket can be observed quickly and if necessary replaced. The inspection hole should always be visible and drainable.
- Weld from the inside of the tank if possible. Welds shall be free from cracks, burr and grooves. Welding should be grinded to Ra ≤ 0.8 µm (Be sure not to grind on the edge of the adaptor hole. Otherwise the connection will not be tight)
- Tighten the connection with the torque stated below
Cleaning
Clean, disinfect or sterilize sensor as needed (CIP/SIP).
Ensure that when installed in a tank both the sensor and the connection are reached by the cleaning agents.
Generally for welding adapters in a tube
- Use only a 3-A/EHEDG approved welding adapter
- Level the inner surface of the pipe with the welding adapter.
- Welds shall be free from cracks, crevices and groves. Welding should be grinded to Ra ≤ 0.8 µm.
- The 3-A mark or arrow shall be placed upwards. Always face the inspection hole downwards, so a leaking gasket can be observed quickly. If necessary to be replaced. The inspection hole should be visible and drainable.
- Always mount the welding adapter in a self-draining position. On a tube; >5° from horizontal. This will give an optional placement of 170° for the location of measuring point (as shown in the drawing)
- Tighten the connection with the torque stated below
Tighten the connection with a torque of:
CombiTemp TFRH G 1/2 A hygienic 20 Nm
After installation and configuration
- Check the leak tightness between the welding sleeve and the instrument
- Check the tightness of glands or M12 plugs.
- Check the tightness of the instrument cover
It is important that a 3-A marked adapter are installed according to these instructions. Always try to limit cracks, crevices and holes where remaining media can accumulate and provide bacteria.
Always replace gaskets or O-rings that are damaged or defect.
Hazardous area (ATEX)
The CombiTemp™ TFRx can be supplied for hazardous area. Eithas a Simple Apparatus with RDT output or with built-in transmitter with 4 … 20 mA output.
A CombiTemp™ TFRx with built in transmitter will have two possible
ATEX approvals, Ex ia (zone 0, 1, or 2) or Ex nA (zone 2).
II 1 G, EX ia IIC T4/T5, Gas
II 3 G, Ex nA IIC T4/T5, Gas
The remaining Ex parameters depend on the type of transmitter andisplay selected for the product. See detailed data below.
The CombiTemp™ TFRx with Ex ia must be installed in accordancwith prevailing guidelines for zone 0 and zone1 and a certified intrinsically safe zener barrier with the listed maximum values must be used. Electrical connection for the temperature transmitter as per below diagram.
CombiTemp™ TFRx with Ex nA must be installed in accordance with prevailing guidelines for zone 2 without a barrier. When using CombiTemp™ TFRx with Ex ia simple apparatus in zone 0 with group IIC explosive atmosphere the housing must be connected to ground.
