Its galvanized steel plate housing makes the 1-pin mechanical thermostat very robust and can also be used in harsh conditions. The measuring system used works according to the principle of liquid expansion and can be used without any problem up to a maximum admissible sensor temperature of 230 °C. The smooth round sensor made of copper has a diameter of 6 mm with a probe length of approx. 78 mm. The remote control cable of the thermostat is also made of copper and can be laid flexibly under consideration of a bending radius of 5 mm. The first 460mm from the switching head are covered with an electrically insulating PVC protective hose. The maximum permissible ambient temperature at the switching head (protection class IP00) is 80 °C. The temperature compensation reduces the influence of the ambient temperature on the control head to a minimum. The switch head is attached using a mounting bridge using two screws M4 x 28. With the help of a setpoint adjuster, which is available as an acc
