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

DESCRIPTION AND APPLICATION

These resistance temperature sensors are intended for measure by contact the temperatures of liquid and gaseous substances. These sensors are manufactured in two versions: the small connection head with resistance output and the large connection head with 4 to 20 mA output.

The sensors are designed for use primarily in the food industry. The sensor - central support combination is suitable for temperature measurement in air conditioning ducts. The sensor/thermowell combination is suitable for measuring the temperature in pipes.

The sensor variant with welded thread is ideal for direct measurement of fluids in ducts. 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.

DECLARATION, CERTIFICATES, CALIBRATION

The manufacturer provides an EU declaration of conformity.
Calibration - The final metrological control - comparison with standards or working instruments - is carried out for all products. The continuity of working standards and measuring instruments is ensured within the meaning of Article 5 of Law No. 505/1990 on metrology. We offer the possibility to supply the calibrated sensors (according to the requirements of EN ISO / IEC 17025) or in an accredited laboratory.
