Relative Humidity Sensors

Climatronics' capacitive relative humidity sensors (P/N 102273 and 102425) are specifically designed for meteorological monitoring systems. Very low power consumption makes these relative humidity sensors ideal for integration with data acquisition systems operating at remote locations. Both sensors provides a linear 0 to 1 VDC output signal corresponding to 0 to 100% relative humidity. The sensors require a minimum of maintenance or calibration and features exceptional resistance to contaminants. Repeatability is also excellent, even after complete sensor saturation. The P/N 102273 sensor maintains its accuracy over the full range of humidity, even in conditions close to condensation. This is accomplished by electronic temperature compensation of the humidity element. The moderately priced P/N 102425 sensor does not have the high overall accuracy of the P/N 102273 and an increase in error at the upper and lower 10% of its range.
