HIH4602-C Datasheet | Honeywell

DESCRIPTION HIH-4602-A/C Series Relative Humidity (RH) sensors bine 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 .. - 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.
