Description

Ceiling built-in humidity and temperature sensors HYGRASGARD® DFTF - Modbus
The calibratable HYGRASGARD® DFTF - Modbus humidity and temperature transmitter measures the relative humidity and temperature of air.

Relative humidity (in % RH) is the quotient of water vapour partial pressure divided by the saturation vapour pressure at the respective gas temperature. The sensor device provides precise detection of temperature and humidity. A digital, long-term stable sensor serves as measuring element for humidity and temperature. Fine adjustment by the user is possible.

The sensor has been designed for use in non-aggressive, dust-free environments and can be installed in suspended ceilings of corridors, offices, as well as residential and commercial buildings. The connecting head is pluggable for quick, easy mounting. The measuring transducer is accommodated in a separate housing.
