Temperature probe with metal connection head

Temperature sensor - Metal connection head *Step required

In production :  2 to 3 weeks
Description and application

These resistance temperature sensors are designed to measure the contact temperature of liquid or gaseous substances. The combination of temperature sensor and central support is suitable for temperature measurements in air conditioning ducts. The combination of temperature sensor and thermowell is suitable for temperature measurements in tubes. The sensor variant with welded thread is ideal for direct measurement of fluids in ducts. The standard operating temperature range is between -30 ° C and 200 ° C. By using a sensor with a longer rod, the upper allowable temperature limit can be extended up to 250 ° C. The temperature sensors can be used for any control system compatible with the output signals of the sensing elements or the output signals shown in the table of sensing element types.

The temperature sensors are designed to operate in a chemically non-aggressive environment.
