Multipoint temperature sensors for all industries

Multipoint temperature sensors

Multipoint temperature sensors for all industries

Multipoint assemblies are products for several applications from low to high pressure process reactors as well as for storage tanks. In these applications a temperature profile for control of the process in the reactor is measured and recorded. The challenge is to be less invasive as possible and to have a high number of temperature probes, enabling the shortest response time.

Material selection, mechanical design, heat treatments and construction technics are the latest state-of-the-art in terms of product optimization.

In the process automation two measurement principles for temperature have asserted themselves as a standard:

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 approx. 600 °C and stand out due to high measurement accuracy and long-term stability. The sensor element most frequently used is a Pt100. As a standard, Endress+Hauser RTD sensors fulfill the IEC 60751 accuracy class A.

TC - Thermocouples: Measuring principle

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 +1800 °C. They stand out due to the fast response time and high vibration resistance.

Benefits

  • Measuring systems designed for the individual application

  • Straight or 3-dimensional temperature profile measurement for reactors and vessels

  • Design and material selection for high process temperatures and pressures as well as corrosive media
