Thanks to its impact-resistant housing made of high-quality plastic, the 1-pole mechanical body thermostat with changeover contact is very robust and can also be used under harsh conditions. The measuring system used works on the principle of liquid expansion and can be used up to a maximum permissible sensor temperature of 149 ° C without any problems. The smooth round copper sensor has a diameter of 6 mm and a sensor length of approx. 66 mm. The thermostat's long-distance line is also made of copper and rolled up inside the housing when it is delivered. Considering a bending radius of 5 mm, the long-distance line can be led out of the housing as required and laid flexibly. The protective sleeve made of brass, nickel-plated, included in the scope of delivery, has a diameter of 8 mm and can be mounted with a G 1/2 thread A according to DIN 3852/2. The maximum permissible ambient temperature on the housing (protection class IP54) is 80 ° C. The housing is fastened directly to the lower part of the housing as a wall mount or with the help of a tensioning strap on a pipe. With the help of a screwdriver, the desired switch-off temperature can be easily set on a scale after removing the housing cover. The set switch-off temperature can be viewed at any time through a viewing window in the housing cover. The safety temperature limiter 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 on the switch head to a minimum. A decisive advantage is that no additional auxiliary energy is required for temperature measurement. The electrical connection is made using PushIn © terminals, which significantly reduces installation time compared to conventional screw connections. The maximum permissible switching capacity is AC 230 V / 16 A. The switching contact (terminal 2) is opened after the set temperature has been reached and the signal contact (terminal 4) is closed at the same time. The switch contact is locked automatically and can only be unlocked manually after the temperature at the sensor has cooled down by approx. 10 K. When the temperature at the sensor cools below -20 ° C, the circuit between terminal 1 and terminal 2 also opens, but closes again when the temperature rises. If the measuring system is destroyed, the circuit is opened permanently, unlocking is then no longer possible. The switch contact is then in a neutral position. The safety temperature limiter can be used very flexibly and is used both in building automation and in heating, air conditioning and ventilation technology. Other areas of application are the plastics industry, apparatus and machine construction, furnace construction and temperature monitoring in laboratory and climatic cabinets. The device is approved according to DIN EN 14597 and PED and has an EAC approval.
