Endress+Hauser Temperature Portfolio

Industrial thermometers for different applications

A broad portfolio of temperature measurement technology for all industries. The measurement principles used are RTD sensors and thermocouples. For the installation of the measurement point into the process, thermowells are available in a variety of materials and process connections to suit.

RTD – Resistance temperature detectors measuring principle:

The RTD sensor changes the electrical resistance with a change in temperature. They are suitable for the measurement of temperatures between -200°C and +600°C and stand out due to a high measurement accuracy and long-term stability. The sensor element most frequently used is a Pt100.

TC – Thermocouples measuring principle:

A thermocouple is a component made of two different metals connected with each other at one end. An electrical potential is caused due to the Seebeck effect at the open end if the connection and the free ends are exposed to the different temperatures. By comparison to thermocouples reference tables (IEC 60584) the temperature at the connection (measuring junction) can be concluded. Thermocouples are suitable for temperature measurement in the range of 0°C to +1800°C. They stand out due to the fast response time and high vibration resistance.

Transmitters for all industrial applications

The task of temperature transmitters is the transformation of the sensor signal into a stable and standardised signal. In the past, transmitters were built using analogue technology. In the meantime digital technology has gained acceptance because it offers better measurement accuracy at simultaneously higher flexibility, improve safety and save costs.

A huge portfolio of modular industrial temperature transmitters:

  • DIN rail mounted for panel installations
  • Head transmitters for direct installation in sensor terminal heads
  • Field temperature for direct connection in the process area
  • Ex approved transmitters
  • All communication protocols available, HART, PROFIBUS, FOUNDATION Fieldbus or PC Programmable


  • Safe operation in hazardous areas with IEC Ex international approvals
  • Diagnostics information according to NAMUR NE 107
  • Optimisation of accuracy by sensor-transmitter matching
  • Sensor monitoring functions
  • Rapid no-tools wiring due to optional spring terminals
