Technical data
7.1 Measuring principle
All of the thermometers described here belong to the class known as "contact thermometers".
Unlike "radiation thermometers", these thermometers come into direct contact with the
medium whose temperature they are to measure.
The "OPTITEMP TR/TC 100" handbook goes into more detail regarding the various basic
physical foundations of temperature measurement using measuring inserts with a Pt100 RTD or
thermocouple.

INFORMATION!
•
The following data is provided for general applications. If you require data that is more
relevant to your specific application, please contact us or your local representative.
• Additional information (certificates, special tools, software,...) and complete product
documentation can be downloaded free of charge from the website (Download Center).
Measuring system
Application range Measuring the temperature of gases, liquids, vapours and solid
bodies in industrial processes. The devices are particularly suited to
liquids with low viscosity, water and chemicals with low
corrosiveness as well as saturated steam and superheated steam.
Measuring principle Contact thermometer
Measured value Temperature
Design
Modular design Industrial thermometers consist of several components which,
together, form an assembly:
• Measuring insert with temperature sensor
• Thermowell with or without neck tube (no thermowell with version
TRA/TCA-P14)
• Connection head
• Transmitter (either inside on the measuring insert or outside)
Signal converter Analogue or digital temperature transmitter in the TT family as head-
mount or rail-mount transmitter.
Sensor Pt100 RTD as thin layer variant (TF) or as wire wound variant (WW) as
per DIN EN 60751.
"J" or "K" type thermocouple as per DIN EN 60584.
Measuring range See "Operating conditions".
