Jumo Capillary Thermostat, Automatic Reset, Surface Mount

The Jumo Mechanical Surface Mounted Double Thermostat is very robust and can also be used in rough conditions. The measuring systems used operate according to the fluid expansion principle and can be used without any problems up to a maximum permissible probe temperature at the temperature controller of 135 °C and at the safety temperature limiter of 149 °C. The smooth round probe made of copper has a diameter of 6 mm. If the measuring system is destroyed, the circuit is permanently opened, unlocking is then no longer possible. The switching contact is then in a neutral position. The thermostat is very flexible and can be used in building automation as well as in heating, air conditioning and ventilation technology. Further areas of application are the plastics industry, apparatus and mechanical engineering as well as furnace construction and temperature monitoring in laboratory and climatic cabinets. The device is approved according to DIN EN 14597 and DGRL and has an EAC approval.
