Thanks to its galvanized sheet steel housing, the 1-pole mechanical built-in thermostat is very robust and can also be used under harsh conditions. The measuring system used works according to the liquid expansion principle and can be used without any problems up to a maximum permissible sensor temperature of 145 °C. The smooth round sensor made of copper has a diameter of 6 mm and a sensor length of approx. 87 mm. The thermostat's long-distance line is also made of copper and can be laid flexibly, provided a bending radius of 5 mm is observed. The first 460 mm from the switch head are covered with an electrically insulating PVC protective hose. The maximum permissible ambient temperature at the switch head (protection class IP00) is 80 °C. The temperature compensation reduces the ambient temperature influence on the switch head to a minimum. The switch head is attached using a mounting bridge with two M4 x 28 screws. The desired switch-off temperature can be easily set on a scale using a setpoint adjuster, which is available as an accessory. The temperature controller is characterized by a high switching point accuracy of +/- 3% in the upper third of the scale. A decisive advantage is that no additional auxiliary power is required for temperature measurement. The electrical connection is made to the flat plugs (A 6.3 x 0.8 DIN 46244) of the switching set, which can directly switch a maximum permissible switching capacity of AC 230 volts / 16 A. The thermostat has a switching difference (hysteresis) of approx. 3 K and automatically switches back to the original state after the switch-off temperature falls below this value. The temperature controller is very flexible and is used in heating, air conditioning and ventilation technology as well as in the plastics industry, apparatus and furnace construction and for temperature monitoring in laboratories and climate cabinets. The device is approved in accordance with DIN EN 1459
