Multi-funtional duct sensor
For humidity, temperature, pressure, differential pressure and volume flow for monitoring and controlling heating, ventilation and air-conditioning systemsPREMASGARD® 814x-Modbus
Für jede Anwendung die richtige Lösung [Translate]
Electronic frost protection thermostat/ frost monitor THERMASREG® FS with continuous and switching output, fully-active copper sensor rod, with additional control input 0 - 10 V and summation output 0 - 10 V. The frost sensor is used to monitor air conditioning systems, heat exchangers, heating registers and similar equipment to prevent frost damage and freezing up. Falling below the limit value at the coldest measuring point of the capillary tube is detected.
In case of capillary breakage, power failure, or electrical damage to at the device, the relay in the frost monitor automatically switches to frost.
MK-05-K mounting clamps are included in the scope of delivery.
