Measuring temperature 29.02.2020 09:51 29.02.2020 09:51

The temperature of liquid flowing in the piping is measured by a temperature sensor with a stem in a stainless steel sleeve fitted in the piping; there is available the CFox module C-IT-0100H-A, the Order No. is TXN 133 17.0x (x - the stem length), and it is necessary to additionally order the appropriate immersion sleeve TXP 300 1x (x - the sleeve length). The module is placed in an aluminium head with a terminal block for the connection of the CIB bus; the metal measuring stem is made of stainless steel, grade DIN 1.4301, the stainless steel sleeve is equipped with a G1/2" screw thread. The standard version of the module is designed for a maximum temperature of 250 ºC. The modules can also be used in the thermally and chemically more demanding environments, with a maximum ambient temperature (the operating temperature of the head itself) at max. 80 °C.
