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 sales office.
• 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 sensor
Measured value Temperature
Design
Modular design Industrial temperature sensors consist of several components which,
together, form a thermometer assembly:
• Thermowell
• Housing
• Electrical connection
• Transmitter (built in or rail mounted )
Signal converter Built-in analog transmitter, OPTITEMP OEM 201
Analogue or digital temperature transmitter in the TT family as rail-
mount transmitter.
Sensor Pt100 RTD as thin layer (TF), class A with a characteristic according
to DIN EN 60751.
Surface roughness(only valid for
TRA-C10)
Ra 0.8, Ra <0.8 electropolished available on request
Measuring range Refer to "Operating conditions".
Measuring accuracy
Reference conditions Ambient temperature: +23°C / +73.4°F (fluctuations due to air
pressure and density have no impact on measuring accuracy).
Maximum measuring error More detailed information in the subsection "Measurement Error"
(also in the "Technical data" section). The maximum measurement
error also depends on the type of sensor:
• Sensor element with Pt100 RTD: measurement error in accordance
with tolerance class A, according to DIN EN 60751.
