603070 / 0170-5-026-671-25-2000-40-10-40-00-0 / 402, double thermostat (TR / STB), 0 to 120 ° C and 70 to 130 ° C, transmission 2000 mm

Double thermostat (TR / STB), 0 to 120 ° C and 70 to 130 ° C, transmission 2000 mm

Due to its impact-resistant housing made of high-quality plastic, the mechanical construction double thermostat is very robust and can also be used under harsh conditions. The measuring systems used are based on the fluid expansion principle and can be used without any problems on the temperature regulator of 135 ° C and the safety temperature limiter of 149 ° C up to a maximum permissible sensor temperature. The smooth copper round sensors have a diameter of 6 mm. The sensor length of the temperature regulator is about 87 mm, the safety temperature limit is about 66 mm. The lines are also rolled out of copper and in case of delivery in the housing. With respect to a 5 mm bending radius, the lines can be removed from the housing as required and moved flexibly. The maximum permissible ambient temperature on the housing (protection type IP54) is 80 ° C. The housing is mounted directly on the housing body as a wall assembly. The desired temperature of the temperature regulator can be easily set on a scale with the help of a set value. The temperature of the safety temperature limiter can be adjusted on a scale with the help of a screw after the case cover has been removed. The set temperature is visible at any time through a window in the housing cover. The temperature controller is characterized by a high switching point accuracy of + / -3% in the upper scale, the safety temperature limiter has a switching point accuracy of + 0 / -5 K in the upper half of the scale. The built-in temperature compensation reduces ambient temperature influences at the head of the switch to a minimum. A key advantage is that no additional auxiliary energy is required for temperature measurement. The electrical connection is made by PushIn © terminals, which significantly reduces the installation time compared to conventional screw connections. The maximum permissible switching power is AC 230 Volt / 16 A. The temperature controller has a switching difference (hysteresis) of approx. 3 K and automatically switches back to the state of origin after the switch-off temperature is below. The switching contact of the safety temperature limiter (terminal 2) is opened after the set temperature is reached and the signal contact (terminal 4) is closed. The switching contact is automatically locked and can only be closed after cooling the temperature on the sensor by approx. 10 K will be unlocked manually again. When the temperature at the sensor is cooled below -20 ° C, the circuit between terminal 1 and terminal 2 also opens, but closes itself again when temperature increases. When the measuring system is destroyed, the circuit is opened permanently, and unlocking is no longer possible. The switching contact is then in a neutral position. The thermostat is very flexible and can be used in building automation as well as in heating, air conditioning and ventilation. Other applications include the plastics industry, equipment and mechanical engineering as well as furnace construction and temperature monitoring in laboratory and climate conditions. The device is approved in accordance with DIN EN 14597 and DGRL and has an EAC approval.
