603070 / 0020 -5-040-000-70-2000-40-10-6-40-00-0 / 402, safety temperature guard, 70 to 130 ° C, transmission line 2000mm

Safety temperature guard, 70 to 130 ° C, transmission line 2000mm

Due to its high-quality plastic case, the 1-pole mechanical construction thermostat is very robust with switching contact and can also be used under harsh conditions. The measuring system used is based on the fluid expansion principle and can be used without any problems up to a maximum permissible sensor temperature of 149 ° C. The smooth copper round sensor has a diameter of 6 mm with a sensor length of about 66 mm. The transmission line of the thermostate is also rolled out of copper and when delivered in the case inside. With respect to a 5 mm bending radius, the transmission line 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 or by means of a tensioning tape on a pipe. With the help of a screwdriver, the desired shutdown temperature can be easily adjusted on a scale after the case cover has been removed. The set shut-off temperature can be seen at any time by means of a vision window in the housing cover. The safety temperature guard is characterized by a high 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 thermostat has a switching difference (hysteresis) of about 3 K and automatically switches back to the state of origin after the switch-off temperature is below. When the temperature at the sensor is cooled below -20 ° C, the circuit opens between terminal 1 and terminal 2, but closes itself again when temperature increases. When the measuring system is destroyed, the circuit is opened permanently, the switching contact is then in a neutral position. The safety temperature guard 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.
