Humidity Transmitter
HygroDat 100-EC Poly Humidity Temperature Transmitter with ploycarbomate housing.
The versatile HygroDat 100-EC Poly Humidity Temperature Transmitter detects by a remote sensor the
actual relative air humidity and temperature value and converts them into an analogue or digital signal.
The very performing micro processor enables as well the calculation and output of other climate parameters
such as dew point, enthalpy, mixing ration etc.
The whole system has been built with an open system architecture what makes it very
flexible.
The sensors can be installed up to 30m respectively 100m, depending on the version, from the
transmitter.
For testing and adjustment purposes, the humidity standards, based on saturated salt solutions can be used.
The HygroDat 100-EC Poly transmits 10...15 times per second the measured values directly to the analogue
outputs, what makes the system very quick and accurate.
The transmitter disposes as well of a automatic calibration function, that allows an easy and quick on site
calibration and check by using the well proved Novasina SC humidity standards
