1. Safety
Intended use
The sensor measures temperatures of liquids and
solids within the range of –40 … 135 °C.
The sensor must only be used for media against
which the housing material and sensor tip are
resistant.
Staff qualication
Only use staff who are trained for the activities
described. This applies in particular to assembly,
installation, conguration and troubleshooting.
Make sure that the staff have read and understood
these instructions.
Technical condition
Only use sensor in perfect technical condition.
Only use Baumer accessories.
Baumer will accept no liability for other
manufacturers’ accessories.
Risk of burns from hot media
During operation the sensor housing may warm
up to over 50 ºC. When working with hot media
provide protection against burns.
2. Construction and function
13 21 Sensor PEEK tip
2 Process connection
3 Electrical connection M12-A
The TER8 is a compact temperature sensor based
on RTD technology. With its PEEK sensor tip the
sensor can be used in hygienic processes. The
output signal is a Pt100 signal or with a built-in
temperature transmitter a 4 … 20 mA signal.

DANGER
Risk of injury from hazardous medium
fOnly use weld-in sleeves or adapters from Baumer.
fWear protective equipment for hazardous media (e.g. acids, alkaline solutions).
fDo not seal the process connections with Teon tape (PTFE) or elastomer.
fEmpty vessel and pipes before mounting.
fCheck leak-tightness of the sleeve.
fCheck tightness of the M12 plug.
9Hole for mounting the sensor is easily accessible
fMount weld-in sleeve or adapter as follows:
 3-A mark or arrow points upwards
 Hygienically and internally ush
fGrind welding to Ra ≤ 0.8 μm.
fScrew in sensor.
Tightening torque: 10 … 15 Nm
