Measurement of relative humidity using Rotronic capacitive Hygromer® sensors allows software based calculation of the dew or frost
(Dp/Fp) point temperature. However, below -30°C Dp/Fp specific sensors are recommended.
ROTRONIC offers dew/frost point sensors that are compatible with the HygroFlex transmitter range, and that can also be used as
autonomous 2-wire loop powered transmitters. The sensors used in these products are aluminium oxide based, and are pre-calibrated
over the specific measurement ranges. |
