Dual device with mechanical capillary thermostat and mechanical capillary limiter for use in explosion hazard areas

Type HT-IRB2M

The Ex controllers / limiters are mechanical 2-point controllers. The glass-fibre reinforced polyester housing is mechanically robust. The combination of controller and limiter allows easy and space-saving operation of an electrical tracer heater in explosion hazard areas. The sensors with just 4 mm outer diameter are especially well suited for electrical trace heaters.
