Due to its glass fiber reinforced polyester case (protection class IP65), the 1-pole mechanical surface mounted thermostat with changeover contact is very robust and can also be used in rough conditions. The measuring system used operates according to the fluid expansion principle and can be used up to a maximum permissible probe temperature of 50°C without any problems. The spiral probe made of stainless steel is fixed on the side of the case. The maximum permissible ambient temperature at the case is -40 to 40 °C in temperature class T6 or max. 70 °C in temperature class T4. The case is fixed directly to the bottom section of the case by means of 4 screws. The desired shutdown temperature can be easily set on a scale with the aid of a screwdriver after removing the case lid. The temperature monitor is characterized by a high switching point accuracy of +0/-2 K in the middle third of the scale. The integrated temperature compensation reduces ambient temperature influences at the switching head to a minimum. A decisive advantage is that no additional auxiliary energy is required for temperature measurement. The electrical connection is made by PushIn© terminals, which significantly reduces installation time compared to conventional screw connections. The maximum permissible switching capacity is AC 230 V / 16 A. The thermostat has a switching differential (hysteresis) of approx. 2.5 % of the scale range and automatically switches back to the original state after the temperature has fallen below the switch-off temperature by this value. The temperature monitor is very flexible and can be used in all explosive atmospheres of ex zones 1, 2, 21 and 22. The device is approved according to ATEX and suitable for temperature class T6 in explosive gas or dust atmospheres. The device is RoHS compliant and cadmium free.
