Humidity Sensors Humidity Sensor
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 * Drying * Metrology * Battery-powered systems * OEM assemblies
HIH-3610 Series
The HIH-3610 Series humidity sensor is designed specifically for high volume OEM (Original Equipment Manufacturer) users. Direct input to a controller or other device is made possible by this sensor's linear voltage 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.
