Humidity Sensors Humidity Sensor HIH-3610 Series FEATURES Molded thermoset plastic housing with cover Linear voltage output vs %RH Laser trimmed interchangeability Low power design High accuracy Fast response time Stable, low drift performance Chemically resistant TYPICAL APPLICATIONS Refrigeration The HIH-3610 Series humidity sensor is designed specifically for high Drying Metrology volume OEM (Original Equipment Manufacturer) users. Direct input to a Battery-powered systems controller or other device is made possible by this sensors linear voltage OEM assemblies output. With a typical current draw of only 200 A, the HIH-3610 Series is ideally suited for low drain, battery operated systems. Tight sensor interchangeability reduces or eliminates OEM production calibration costs. Individual sensor calibration data is available. The HIH-3610 Series delivers instrumentation-quality RH (Relative Humidity) sensing performance in a low cost, solderable SIP (Single In-line Package). Available in two lead spacing configurations, the RH sensor is a laser trimmed thermoset polymer capacitive sensing element with on-chip integrated signal conditioning. The sensing element s multilayer construction provides excellent resistance to application hazards such as wetting, dust, dirt, oils, and common environmental chemicals.

Extended exposure to 90% RH causes a reversible shift of 3% RH. 2. This sensor is light sensitive. For best results, shield the sensor from bright light. 2 Honeywell Sensing and Control For application help: call 1-800-537-6945
