Multi-Layer Ambient Sensors

August 1, 2008

Saelig (Pittsford, NY) has released the UPSICAP™ line of passive and active sensors that measure ambient temperature and relative humidity. The 9 × 8-mm passive elements vary capacitance with humidity and resistance with temperature, and are interchangeable without recalibration. The sensors feature a fourlayer construction, which makes them resistant to water immersion and condensation. The sensors can operate from 0 to 100% relative humidity, and from -90° to 85°C. They are designed for use in weather measurement, aeronautics, and military applications.
