The sensor consists of a plastic head and a metal tube in which a temperature sensor is placed. The metal tube has a screw connection with a standard G 1/2 "thread. In the head there is a terminal block or converter, to which the power cable for the sensor and the digital output signal is connected. 

SD 162, communication protocol SD 162K MODBUS / RTU, RS485 communication

The sensors are designed to operate in a chemically non-aggressive environment, the method of use must be chosen according to the temperature and the chemical resistance of the sensor head.
