HIH-4602-A/C Series Humidity Sensors DESCRIPTION HIH-4602-A/C Series Relative Humidity (RH) sensors combine both relative humidity and temperature sensing in a TO-5 housing with a hydrophobic sintered stainless steel filter. The laser-trimmed, thermoset polymer capacitive sensing elements have on-chip integrated signal conditioning. The temperature sensor is thermally connected with the RH sensor making the HIH-4602-A/C often ideal for measuring dew point and other absolute moisture terms. FEATU.

HIH-4602-A/C Series Humidity Sensors DESCRIPTION HIH-4602-A/C Series Relative Humidity (RH) sensors combine both relative humidity and temperature sensing in a TO-5 housing with a hydrophobic sintered stainless steel filter. The laser-trimmed, thermoset polymer capacitive sensing elements have on-chip integrated signal conditioning. The temperature sensor is thermally connected with the RH sensor making the HIH-4602-A/C often ideal for measuring dew point and other absolute moisture terms. FEATURES • Near linear voltage output vs %RH • Laser-trimmed interchangeability • Enhanced accuracy, fast response • Chemically resistant www.DataSheet4U.com • Stable, low drift performance • Built-in static protection • Often ideal for dew point and absolute moisture measurements • TO-5 housing POTENTIAL APPLICATIONS • Refrigeration • Drying • Meteorology • Battery-powered systems • OEM (Original Equipment Manufacturer) assemblies The HIH-4602-A contains an integral thermistor, while the HIH4602-C contains an integral precision RTD. Factory calibration data supplied with each sensor allows individually matched downstream electronics and ±3.5 %RH total accuracy. HIH-4602-A/C Series TABLE 1.
