Temperature sensor with stainless steel head and plunger for the food industry

Temperature probe with stainless steel head and plunger for the food industry

In production :  2 to 3 weeks
Description and application

These resistance temperature sensors are designed to measure the temperatures of liquid and gaseous substances by contact. These sensors are manufactured in two versions: the small connection head with resistance output and the large connection head with output 4 to 20 mAThe sensors are designed for use primarily in the food industry. The sensor - central support combination is suitable for measuring the temperature in air conditioning ducts. The sensor - thermowell combination is suitable for measuring the temperature in the tubes. The sensor variant with welded thread is ideal for direct measurement of fluids in conduits. The standard operating temperature range for active sensors is between -50 and 150 ° C. For passive sensors, it is between -50 and 200 ° C.

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