These resistance sensors are intended for contact measurement of the temperature of liquid or gaseous substances. The sensors consist of a metal measuring stem and a plastic head. All metal parts are made of stainless steel class 17 240. The basic lengths of measuring stems are 70, 120, 180 and 240 mm. The plastic head is equipped with a cable gland (a terminal block is located in the head) or a connector. The sensors comply with the degree of protection IP 65 according to ČSNEN 60 529. The central holder and the well are supplied as accessories. The combination of the sensor and the central holder is designed to measure the temperature in air conditioning ducts. The combination of the sensor and the sink is intended for measuring the temperature in pipes. The sensors can be used for all control systems that are compatible with the sensors or active outputs listed in the technical parameters table. The standard temperature range for using sensors is -30 to 150°C. By extending the length of the stem, it is possible to use sensors up to temperatures of 250 °C. The sensors are intended for operation in a chemically non-aggressive environment. Special use: The requirement for a sensor for use in areas with a risk of explosion - zone 2 must be specified in the order. Sensors with a resistive output and a cable gland can be used in areas with a risk of explosion - zone 2. They are approved according to the ČSN EN 50 021 standard and marked with a code II 3G EEx nA II T6. The temperature range of use in areas with a risk of explosion is - 20 to 85 °C and must not be exceeded even for a short time.
