Product features Plunger Temperature Sensor - Mini Series

DESCRIPTION AND APPLICATION

These resistance temperature sensors of the MINI series are designed for measuring the temperature of liquid or gaseous substances in the temperature range between -30 and 150°C. The plastic connection head is equipped with a cable outlet (the terminal block is placed in the connection head) or a connector.

la sensor-central support combination suitable for temperature measurements in air conditioning ducts. Lakesensor-thermowell combination suitable for temperature measurements in tubes. The sensor variant with welded thread is ideal for direct measurement of fluids in pipes.

By using a sensor with a longer rod, the upper limit of the allowable temperature can be extended up to 250°C. The sensors are designed to operate in a chemically non-aggressive environment.

ACCESSORIES

Central plastic support
JS 130 stainless steel thermowell
K 120 central metal support
CONEC 43-00092 input connector
Connection cable with straight connector RKt or rectangular connector RKWt
Screw with collar or cutting rings - if different immersion lengths of the temperature sensor are set

DECLARATION, CERTIFICATION, 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 standards and work measurement instruments is ensured within the meaning of article 5 of Law No. 505/1990 on metrology. The manufacturer offers the possibility of supplying the calibrated sensors (according to the requirements of EN ISO / IEC 17025) or in an accredited laboratory.
