Resistance Thermometers


The optimal solution for every application

Thermo Sensor resistance thermometers

Our resistance thermometers are successfully used for temperature measurements in industrial applications.

Temperature dependence of the electric resistance of metals, semi-condustors and ceramics is used as measuring effect. By voltage drop measurements the temperature-affected resistance can be recorded. 

Our sensors have a high accuracy. We are able to offer sensors made of 1/10 class B (0.03 °C at 0 °C). Having to withstand adverse conditions during long-duration measurements resistance thermometers made by Thermo Sensor are long-time stable and are frequently used in research and development laboratories.

Thermo Sensors resistance thermometers are available in many versions and different types, e.g. Pt100, Pt500, NTCs and PtCs as well as many installation options for example as bayonet caps, magnets, glue pads, protectiv tubes or screw-in sensors.

For certain applications we offer various certificates. Our sensors are applicable for temperature ranges from -200 °C up to +800 °C.

Advantages at a glance:
  • Highly-precise
  • Largely resistant against electrical disturbances
  • Long-time stable
  • Almost linear characteristic

Resistance Thermometers in Shell or Tube Construction

resistance thermometers with bayonet cap

Resistance thermometers in shell or tube construction are particularly suitable for temperature measurements in hard-to-reach places thanks to their small dimensions. Despite their dimensions, they still offer maximum flexibility.

Due to their short response times, they are ideal for the exact measurement of temperature fluctuations and can also be used without an additional protective fitting due to their closed design.

Resistance sensors are suitable for a wide range of applications. For example, they are used in laboratories because of their accuracy and fast response time.

Resistance sensors with thermowells are frequently used

  • in the packaging industry
  • for injection molding machines
  • in transformer construction

There are many possible combinations with regard to the process connection, the installation length or the cable types - always exactly fitting for each individual application.

Advantages at a glance:
  • heat-resistant
  • versatile
  • robust
  • shockproof

Resistance thermometers equipped with bayonet cap are extremely robust and suitable for high temperature ranges up to +400 °C. They can be easily installed and removed from the test object without tools are therefore versatile in use. For adapting to the surrounding conditions different insulating material is available. Cable ends can be preassembled upon request or delivered with mounted plug.

Bayonet sensors are mainly used
  • in plastic processing
  • in injection molding machines
  • in pipelines and containers

Surface Resistance Thermometers

Surface Resistance Thermometers

Due to their special mounting options, surface sensors are particularly suitable for measurement on pipelines or vessel walls. The resistance sensor constantly and reliably measures the temperature of the surface. It can be fixed quickly and easily to the surfaces at the place of use by means of the various fastenings.

Typical Applications:

  • Pipelines
  • Injection molding machines
  • Containers

Advantages at a glance:

  • Fast fixation
  • Constant temperature measurement

 

Industrial Resistance Thermometers

Industrial Resistance Thermometers

Resistance thermometers for industrial applications are particularly heat-resistant and partly suitable for temperature ranges from -200 °C up to +800 °C, depending on the materials and components used. Commonly used materials are platinum, various ceramics or heat-resistant steels.

They are versatile because they are extremely robust against external influences such as flue gases or aggressive liquids.

There are various combination possibilities, e.g. regarding connecting head, installation and neck length, or the connections to the protective tube. All our resistance sensors are also available on request in accordance with class A, 1/3 B or 1/10 B tolerances.

Typical applications:
  • Heat treatment
  • Automotive industry
  • Aluminium and steel processing industry
  • Recycling
  • Construction and mechanical engineering
  • Energy production
  • Heat engineering
Advantages at a glance:
  • extremely heat-resistant
  • versatile
  • robust
  • suitable for temperature range from -200 °C up to +800 °C
