Thanks to its impact-resistant housing with high-quality plastic, the mechanical double-body thermostat is very robust and can also be used under harsh conditions. The surface-mounted double thermostat impresses with both its user-friendliness and its visually appealing design. The device consists of a temperature monitor and a safety temperature limiter (STB), which, after removing the housing cover, can be used to set the desired switch-off temperature independently on a scale using a screwdriver. The temperature monitor is characterized by a high switching point accuracy of +/- 1.5% in the upper third of the scale and has a switching difference (hysteresis) of approx. 2.5% of the scale range. It switches off after reaching the switch-off point and automatically returns to its original state after the switch-off temperature has fallen below the value of the switching difference. If the temperature at the temperature sensor of the safety temperature limiter exceeds the set limit, the circuit is opened and the microswitch is locked mechanically. After the danger temperature has dropped below approx. 10 K, the safety temperature limiter can be unlocked manually by pressing a button. It is characterized by a high switching point accuracy of + 0 / -5 K at the limit value. If the measuring system is destroyed, the circuit of the STB is opened permanently, unlocking is then no longer possible. The switch contact of the safety temperature limiter is then in a neutral position. A decisive advantage is that no additional auxiliary energy is required for temperature measurement. The electrical connection is made using screw terminals up to 2.5mm² cable cross-section. The maximum permissible switching capacity of AC 230 volts / 10 A can be switched directly. The measuring systems used work on the principle of liquid expansion and can be used up to a maximum permissible sensor temperature of 135 ° C without any problems. The brass immersion tube has a diameter of 15 mm. It is fastened using a G 1/2 thread A according to DIN 3852/2. The maximum permissible ambient temperature on the housing (protection class IP54) is 80 ° C. The thermostat can be used very flexibly and is specially designed for the heating, air conditioning and ventilation industries. The device can also be used wherever temperature control with a safety function is necessary.
