603026 / 0170-1-052-30-0-00-20-13-46-150-15-6 / 000, double thermostat (TR / STB), 30 to 110 ° C, installation length 150 mm

Double thermostat (TR / STB), 30 to 110 ° C, installation length 150 mm

Due to its impact-resistant housing with high-quality plastic cover and aluminium pressure cast base, the mechanical construction double-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 adjustment of the temperature regulator is done with the help of a sensor on a scale. The desired switch-off temperature of the safety temperature limit can be set on a scale after the case cover has been removed by means of a screw-off. & lt, br & gt, The temperature controller is characterized by a high switching point accuracy of + 0 / -1.5% in the upper scale and has a switching difference (hysteresis) of about 3 to 4% of the scale. After the switch-off point is reached, it automatically switches back to the state of origin by the value of the switch-off difference after the switch-off temperature is down. & lt, br & gt, if the temperature at the temperature sensor of the safety temperature limit exceeds the set limit, the circuit is opened and the microswitch is mechanically locked. After the temperature of the danger is below about 10% of the scale can be manually unlocked the microswitch of the safety temperature limit. It is characterized by a high switching point accuracy of + 0 / -5% in the upper scale. When the measuring system is destroyed, the circuit of the STB is opened permanently, and unlocking is no longer possible. The switching contact of the safety temperature limiter is then in a neutral position. When the sensor is cooled to a temperature below approx. -20 ° C the circuit of the STB is also opened, only when the temperature is increased by about -20 ° C can be unlocked by the reswitch button by hand. & lt, br & gt, A key 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 directly switch a maximum permissible switching power of AC 230 Volt / 10 A. & lt, br & gt, The measurement systems used operate according to the fluid expansion principle and can be used without any problems up to a maximum permissible sensor temperature of 135 ° C. The diving tube made of brass, nickel plated, has a diameter of 15 mm. The mounting is done by a thread G 1 / 2 form A according to DIN 3852 / 2. The maximum permissible ambient temperature on the housing (protection type IP54) is 80 ° C. & lt, br & gt, The thermostat is very flexible to use and is used in the heating, air conditioning and ventilation technology as well as in the plastics industry, equipment and mechanical engineering as well as in the furnace construction, district heat transfer stations and for temperature monitoring in the laboratory and climate cabinets. The device is approved in accordance with DIN EN 14597 and DGRL and has an EAC approval.
