Frost-protection monitor

TFC7B12F001

The TFC frost-protection monitor with capillary-tube sensor is used, for instance, to protect heating coils (air side), water drains and ducts against freezing by monitoring the temperature, and to report the risk of frost. The robust, splash-proof, light-alloy casing and the vibration-proof snap switch enable the monitor to be used in heavy-duty applications. The capillary-tube sensor is made of copper.
