The 083F Relative Humidity Sensor is a highly sensitive and stable temperature measurement tool that provides outstanding accuracy. It is reliable in the full range of relative humidity conditions, from 0-100%, performing equally well in meteorological, industrial, laboratory and other demanding settings. Model 085A is a combined relative humidity/temperature sensor. Both sensors can be used with a variety of radiation shields.
The 083F/085A Relative Humidity Sensor measures variance in the capacitance change of a one-micron thick dielectric polymer layer. This film absorbs water molecules through a metal electrode and causes capacitance change proportional to relative humidity. The thin polymer layer reacts very quickly, providing up to 90% of the final value of relative humidity in fewer than five seconds. The sensor’s response is essentially linear, with small hysteresis, and negligible temperature dependence.
- All solid-state construction, digital electronics
