Industrial temperature sensors
Industrial thermometers for reliable and accurate temperature measurements in different applications
Endress+Hauser offers a wide range of temperature measurement technology for comprehensive solutions for almost all branches of industry. The measuring principles used are RTD sensors and thermocouples. Important aspects for the inclusion of the measurement point into the process are the protection of the thermometers through thermowells and the process connection. Many years of experience and our broad application know-how ensure that our industrial temperature sensors meet all customer needs.
Our high-quality temperature sensors are mainly used in the chemical industry, but they also find their use in other areas of the process industry, both in core as well as peripheral processes.
Our huge portfolio of industrial temperature sensors provides:
Thermometers with or without transmitter
Thermometers with or without displays
Threaded, compression fitted and flanged process connections
Fabricated thermowells with or without flange
Thermometers for screwing into an existing thermowell
Thermometers without thermowell – for direct medium contact
In process automation, two measurement principles for temperature have asserted themselves as a standard:
Measuring principle of resistance temperature detectors
The RTD sensor changes its electrical resistance with a change in temperature. They are suitable for the measurement of temperatures between -200 °C and approx. 600 °C and stand out due to high measurement accuracy and long-term stability. The most frequently used RTD types are Pt100 or Pt1000. As a standard, Endress+Hauser RTD sensors fulfill the IEC 60751 accuracy class A.
Measuring principle of thermocouples
A thermocouple is a component made of two different metals connected with each other at one end. An electrical potential (thermoelectric force) is caused due to the Seebeck effect at the open end if the connection and the free ends are exposed to different temperatures. With the help of the so-called thermocouples reference tables (see 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 +1,800 °C. They stand out due to the fast response time and high vibration resistance.
