Thanks to its impact-resistant housing with high-quality plastic cover and die-cast aluminum base, the mechanical surface-mounted double thermostat is very robust and can also be used under harsh conditions. The device consists of two temperature monitors, where the desired switch-off temperature can be set independently of one another on a scale using a screwdriver after removing the housing cover. <,br>,The temperature monitors are characterized by a high switching point accuracy of +0/-1.5% in the upper third of the scale and have a switching difference (hysteresis) of approx. 3 to 4% of the scale circumference. After the switch-off point is reached, the temperature monitors switch off and after the temperature falls below the switch-off temperature by the value of the switching difference, they automatically return to their original state. A decisive advantage is that no additional auxiliary power is required to measure the temperature. The electrical connection is made via screw terminals directly to the built-in microswitches, which can directly switch a maximum permissible switching capacity of AC 230 Volt / 10 A. <,br>,The measuring systems used work according to the liquid expansion principle and can be used without problems up to a maximum permissible sensor temperature of 175 °C. The immersion tube made of nickel-plated brass has a diameter of 15 mm. It is attached using a G 1/2 Form A thread in accordance with DIN 3852/2. The maximum permissible ambient temperature on the housing (protection class IP54) is 80 °C.<,br>,The thermostat is very flexible and is used in heating, air conditioning and ventilation technology as well as in the plastics industry, apparatus and mechanical engineering, in furnace construction, in district heating transfer stations and for temperature monitoring in laboratories and climatic cabinets. The device is approved according to DIN EN 14597 and has an EAC approval.
