Thanks to its impact-resistant housing with high-quality plastic cover and die-cast aluminum base, the mechanical double-body thermostat is very robust and can also be used under harsh conditions. The device consists of a temperature controller and a safety temperature limiter (STB). The temperature of the temperature controller is set on a scale with the aid of a setpoint adjuster. The desired switch-off temperature of the safety temperature limiter can be set on a scale using a screwdriver after removing the housing cover. & lt, br & gt, The temperature controller is characterized by a high switching point accuracy of + 0 / -1.5% in the upper third of the scale and has a switching difference (hysteresis) of approx. 3 to 4% 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. & lt, br & gt, 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. The microswitch of the safety temperature limiter can be unlocked manually after the temperature drops below approx. 10% of the scale. It is characterized by a high switching point accuracy of + 0 / -5% in the upper third of the scale. 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. When the sensor cools down to a temperature below approx. -20 ° C, the circuit of the STB is also opened.Only when the temperature rises above approx. -20 ° C can the STB be unlocked again manually using the restart button The advantage is that no additional auxiliary energy is required for temperature measurement. The electrical connection is made by screw terminals directly on the built-in microswitches, which can switch a maximum permissible switching capacity of 230 V AC / 10 A directly. & lt, br & gt, The measuring systems used work according to the liquid expansion principle and can be used up to a maximum permissible sensor temperature of 175 ° C without any problems. The dip tube made of brass, nickel-plated, 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 (degree of protection IP54) is 80 ° C. & Lt, br & gt, The thermostat can be used very flexibly and is used in heating, air conditioning and ventilation technology as well as in the plastics industry, apparatus and mechanical engineering and used in furnace construction, in district heating transfer stations and for temperature monitoring in laboratories and climatic chambers. The device is approved according to DIN EN 14597 and PED and has an EAC approval.
