SURFACE SENSING THERMOSTAT WITH SAFETY LIMITER FOR HAZARDOUS AREA

A surface sensing thermostat providing temperature control and temperature limit in hazardous areas. The safety limiter prevents the heating system exceeding a preset maximum temperature should the control function fail to operate or an unsafe process temperature occur. The maximum rated voltage is 400 VAC.

The switching current capacity is 16 A maximum via independent Ex d single pole change over micro switches with volt-free contacts. The switches are mounted within an Ex e enclosure together with a spring-type terminal block for fast easy connection. The sensors are 3-meter long stainless steel fluid-filled bulb and capillary.

The thermostat is delivered with Ex approved power cable glands and plugs and the entries offer the possibility for a variety of connections such as connecting M25 and M20 glands for direct heating cable entry or alarm output. The thermostat with limiter is available in 3 temperature ranges: +0°C +120°C, +0°C +200°C and +50°C +300°C
