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 monitor (STW). The temperature of the temperature controller is set on a scale with the aid of a setpoint adjuster. The desired shutdown temperature of the safety temperature monitor 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, The safety temperature monitor is characterized by a high switching point accuracy of + 0 / -5% in the upper third of the scale and has a switching difference (hysteresis) of approx. 4 to 6% 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. In addition, the safety temperature monitor has a self-monitoring function so that the STW circuit is permanently opened if the measuring system is destroyed. The switching contact of the STW is then in a neutral position so that no contacts are switched. Furthermore, when the sensor cools down to a temperature below approx. -20 ° C, the circuit is also opened, and the contact is only closed again when the temperature rises above approx. -20 ° C. & Lt, br & gt, A decisive advantage is that for temperature measurement no additional auxiliary energy is required. 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 140 ° 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.
