Thermocouples


The right sensor for each measuring task

Thermo Sensor thermocouples

Thermocouples made by Thermo Sensor are used successfully for temperature measurements in solid, liquid or gaseous media up to +1,600 °C and are available in various designs and versions.

Due to the high accuracy and quick response times our thermocouples enjoy a high degree of confidence among our customers. In addition, the simple operation ensures quick results. Because of our product variety we are able to offer you the best solution in nearly all industrial applications.  All our thermocouples are made of class 1 material. We can also supply thermocouples made of half class 1 material with a maximum deviation of 0.5 °C upon special request. Particularly in the field of the fast responding sheath thermocouples Thermo Sensor is setting standards by producing sensors from a diameter of 0.15 mm.

Frequent calibration tests in our excellently equipped DAkkS accredited calibration laboratory as well as detailed quality controls guarantee a consistent accuracy of our temperature sensors.
For use in potentially explosive atmospheres we are able to offer sensors according to ATEX and IECEx

For certain applications, we also offer sensors that are approved according to "nA" for the Ex range of zone 2. This allows Thermo Sensor to provide the optimal solution in almost all industrial applications.

Our customers include numerous renowned companies in the automotive industry, food industry, glass industry, chemical and pharmaceutical industry as well as aluminium and steel processing companies.

Wire Thermocouples

Wire Thermocouples
Wire Thermocouples

Our flexible wire thermocouples are available in a variety of designs - depending on the application, we can provide you with a sensor that is tailored to the measuring task. Typical areas of application are surface temperature determination, the detection of component temperatures, the measurement by drag elements in industrial furnaces or the control in the heating, cooling and ventilation technology.

Often, a thermocouple connector is connected to the wire. In this version, the sensor can be easily connected to the evaluation unit or data logger. The probes are available in various lengths and diameters in many different designs, for example with adhesive pad, magnet, bayonet cap or as a pipe clamp probe.

Due to their low mass, wire thermocouples offer the advantage that they have a particularly fast response time. They are flexible and available in a variety of design options.

 

Typical applications:
  • Surface Measurements
  • Evaluation of component temperatures
  • Drag elements in industrial furnaces
  • Heating, Cooling and Ventilation Technology
Advantages at a glance:
  • flexibly applicable
  • wide variety of designs
  • fast response times

Mineral-Insulated-Thermocouples

Mineral-Insulated Thermcouple

Mineral-insulated thermocouples are used for precise temperature measurements. Due to their mechanical robustness and shock resistance and easy handling they can withstand different requirements. Thermo Sensor is able to supply mineral-insulated thermocouples from a diameter of 0.15 mm - ideal for use in confined spaces.

They have fast response times and a special internal design that allows to be used with high pressures and vibrations. Their wide temperature range makes them extremely heat-resistant and allows measurement in both liquid and gaseous media.

They are versatile and widely used in the industry. Due to their enormous flexibility, they are ideal for difficult spatial conditions and are preferably used where a flexible use is desired.

All our mineral-insulated thermocouples can be supplied completely assembled with thermocouple wire or thermocouple plug on request. We can also supply almost any of our mineral-insulated thermocouples with a swaged measuring tip. Swaged thermocouples combine two characteristics - they are extremely robust and yet retain their fast response time.

 

Typical applications:
  • Mechanical Engineering
  • Aluminium and Steel Processing Industry
  • Power Plants
  • Test Rigs
  • Oven and Boiler Engineering
Advantages at a glance:
  • extremely heat-resistant
  • easy to handle
  • shock-resistant
  • flexible
  • robust

Industrial Thermocouples

Industrial Thermocouples
 

Industrial thermocouples are preferable for high temperature ranges. Thanks to their enormous robustness thermocouples for industrial applications are versatile and primarily suitable for measuring temperatures in gaseous, liquid and plastic media. The respective characteristics particularly depend on the materials used. Frequently used materials are platin, different ceramics and heat-resistant steels.

Typical applications:
  • Heat treatment
  • Aluminium and Steel Processing Industry
  • Mechanical Engineering
  • Industrial Furnace Construction
Advantages at a glance:
  • extremely heat-resistant
  • ersatile
  • very robust

 

 

High-Temperature Thermocouples

High-Temperature Thermocouples

High-Temperature thermocouples are particularly suitable for use in extremely high temperature ranges. The platinum thermocouple type R, S, B and C as well as the manufactured materials withstand temperatures up to 1,800 °C. The double protective tubes made of ceramic or metal provide the necessary heat resistance.

For example, our high-temperature sensors are reliable in temperature measurements in hot gas environments in the glass, ceramics and metal industries and heat treatment and combustion processes, due to their temperature resistance.

 

Typical Applications:
  • Glass Industry
  • Ceramic Industry
  • Metal Industry
  • in Heat Treatment Processes
  • in Combustion Processes

For the exact temperature measurements in glass melts, Thermo Sensor mainly manufactures thermocouples with precious metal thermal pairing. For example, sensors with platinum protective tubes or ceramic protective tubes with platinum tip. Platinum elements have a particularly long service life on the one hand, but also an extremely high temperature resistance up to almost 1,650 °C and a high measuring accuracy.

Thermo Sensor offers different types of these special thermocouples, e.g. with different protective sleeves or as an angle design - always precisely adapted to the respective project requirements. At the company's headquarters in Werne, Thermo Sensor manufactures thermocouples type K, type N, resistance sensors, standard or mini plugs, as well as high-temperature ceramic sensors and clamping fittings.

 

Vacuum-tight Temperature Sensors

Hochtemperatursensoren

There are metals that can only be heat treated under inert gas, reaction gas or in vacuum. For this purpose, vacuum-tight temperature sensors from Thermo Sensor are used to maintain the appropriate atmosphere during the process.

As a vacuum-tight sensor, Thermo Sensor, for example, offers straight elements with up to 2 measuring points. These are available e.g. in the versions type K, N, S, R, B or also C and D. Various connection heads or housings are also possible. The connection to the furnace or the system can be carried out differently, e.g. by means of a tightly welded KF flange or also by means of a vacuum-tight pipe crushing screw.

 

The pipe crushing has the advantage that the thermocouple can be moved in its immersion depth. Since the vacuum thermocouples are pipe constructions, the elements are not bendable. Just like all other sensors in our company, every vacuum-tight sensor undergoes a final check. In addition, we perform a leak test on the vacuum-tight probes. For this purpose, a vacuum between 10 -7 and 10 -9 mbar is generated.

If you would like to check your sensors for vacuum tightness, we are happy to offer you this service. Contact us, we will be happy to support you! Depending on your wishes, we will also issue you a certificate of tightness per sensor.
