Baumer CombiTemp TFRH User manual

EN/2018-03-14 Design and specifications subject to change without notice
CombiTemp™ TFRx is a temperature sensor, based on RTD technolo-
gy, 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 sen-
sor. The product offers great flexibility in respect to modification, ser-
vice and maintenance.
The sensor can be made to feature a RTD output signal or with a built
in FlexTop™ temperature transmitter types 2202, 2211 and 2221 with
4-20 mA output (for documentation of FlexTops, please see relevant
data sheet or operating instructions).
Field of application
Valid for FlexTop™ 2202 / 2211 / 2221
The FlexProgrammer configuration unit must not be connected to
the FlexTop within the hazardous area.
Configuration procedure:
a. Disconnect mains from the 4...20 mA loop circuit
b. Disconnect the product from the security within the hazardous
area
c. Bring the product to the safe area
d. Connect the FlexProgrammer and perform the configuration
e. Reinstall the product in the hazardous area
f. Connect the power supply to the circuit
For FlexTop™ 2221 only
Configuration for the FlexTop™ 2221 can be made within the hazard-
ous area by means of a handheld HART configurator, providing the
precautions and guidelines described in the product’s manual are ob-
served.
The CombiTemp TFRx is ATEX approved with transmitter for Ex nA for
zone 2.
The CombiTemp TFRx is ATEX approved without transmitter, i.e. with
Pt100 output only, as simple apparatus as Ex ia.

Mounting for TFRN
The CombiTemp™ TFRN can be mounted in several different ways.
1. 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 connec-
tion 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.
2. 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.
3. 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 approved and EHEDG certified products:
Generally for welding adapters in a tank
1Use only a 3-A approved counterpart.
2Level the inner surface of the tank with the welding adapter.
3 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.
4Weld 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.
5Tighten the connection with the torque stated below
Generally for welding adapters in a tube
1Use only a 3-A approved welding adapter
2Level the inner surface of the pipe with the welding adapter.
3Welds shall be free from cracks, crevices and groves. Welding
should be grinded to Ra 0,8 µm.
4The 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.
5Always 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)
6Tighten 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.

The CombiTemp™ TFRx with Ex ia must be installed in accordance
with prevailing guidelines for zone 0 and zone1 and a certified intrin-
sically safe zener barrier with the listed maximum values must be
used. Electrical connection for the temperature transmitter as per
below diagram.
