Relative humidity transmitter 0 - 100 %rH, -20 ... +90 °C | RHT

duct-mountthin-film2-wire

Using thin-film sensor with capacitance changing proportionally to medium relative humidity, RHT measures RH of air and non-aggressive gases and converts it into standard 4...20mA 2-wire signal. A built-in temperature drift compensation system guarantees good stability of measurement and an additional temperature sensor or second 2-wire transmitter may be built-in for measurement of both medium relative humidity and temperature. The RH transmitter is factory calibrated and does not need custom adjustment, while the temperature transmitter can be additionally calibrated on-site. The device is available in 3 variants with different mounting and temperature ranges. All this, in addition to the high protection class, the small size, and the low price, make RHT a convenient solution for many RH measurement applications.
