DESCRIPTION The HIH-4000 Series delivers instrumentation-quality RH The HIH-4000 Series Humidity Sensors are designed (Relative Humidity) sensing performance in a competitively specifically for high volume OEM (Original Equipment priced, solderable SIP (Single In-line Package). Manufacturer) users. Available in two lead spacing configurations, the RH sensor is Direct input to a controller or other device is made possible by a laser trimmed, thermoset polymer capacitive sensing this sensor's near linear voltage output. With a typical current element with on-chip integrated signal conditioning. draw of only 200 A, the HIH-4000 Series is often ideally suited for low drain, battery operated systems. The sensing element's multilayer construction provides excellent resistance to most application hazards such as Tight sensor interchangeability reduces or eliminates OEM wetting, dust, dirt, oils and common environmental chemicals. production calibration costs. Individual sensor calibration data is available. FEATURES POTENTIAL APPLICATIONS Molded thermoset plastic housing Refrigeration equipment Near linear voltage output vs % RH HVAC (Heating, Ventilation and Air Conditioning) Laser trimmed interchangeability equipment Low power design Medical equipment Enhanced accuracy Drying Fast response time Metrology Stable, low drift performance Battery-powered systems Chemically resistant OEM assemblies Table 1.
