All models provide accurate and reliable dew point measurements over a wide range for energy management and process applications.
Accuracy for the series is +/- 0.5ºC (+/- 1ºF). Dew point may be measured over a range of -40º to +58ºC (-40º to +136ºF).
The wall mount version is also available with an optional air temperature measurement capability over the same range.
In the Dew-10 sensor, a miniature heat pump cools a metallic mirror. When the mirror temperature reaches the dew point of the surrounding air, a thin dew layer condenses on the mirror surface.
This condensation is optically detected. A feedback loop keeps the mirror at the exact dew point by continuously controlling the mirror temperature.
A precision RTD (Resistance Temperature Detector) is imbedded just beneath the surface of the mirror, allowing the dew point temperature to be accurately measured.
Maintenance is easy. Ambient temperature effects, hysteresis, and calibration drift with age are virtually non-existent.
Filter replacement and cleaning the mirror with a cotton swab restores the transmitter to its original condition.
