These resistance-type sensors are intended for contact measurements of temperatures of liquid and gaseous substances. These sensors are produced in two versions: the small connection head with theresistance-type output and the big connection head with the output 4-20 mA. Furthermore, there are versions with a grommet or a connector. The sensor stem as well as the connection head are made of the EN X5CrNi18-10 (DIN 1.4301) class stainless steel. The basic lengths of the measuring stems are 70, 120, 180 and 240 mm.
The stainless steel thermowell JS 130, the metal central holder for temperatures over 150°C, lead-in connector ELKA4012 or lead-in cable with the straight-type RKT connector or rectangular-type RKWT connector can be delivere as accessory.
The sensors are designed to be used in the food-processing industry mainly. The sensor - central holder combination is designed to measure temperature in air condition ducts. The sensor - thermowell combination is designed to measure temperature in tubing. The sensors can be utilised for any control system that is compatible with sensing elements or output signals quoted in the specification table.
The standard temperature range in which the active sensors are allowed to be utilised is -30 to +150°C, for the passive sensors the range is -30 to +200°C. All these sensor types meet the IP 67 ingress protection requirements according to the EN 60 529 standard.
The sensors are designed to be operated in a chemically non-aggressive environment.
Used sensing elements: Ni 1000/5000, Ni 1000/6180, Ni 891, Ni 10000/5000, Ni 10000/6180, Ni 2226, Pt 100/3850, Pt 500/3850, Pt 1000/3850, thermistor NTC 20kΩ.
