The HIH-4602-A/C series relative humidity (RH) sensors are housed in a TO-5 package with a water-proof sintered stainless steel filter mesh that senses relative humidity and temperature. The RH sensor is a laser-corrected, thermoset polymer capacitive sensing element with an embedded signal processing unit. The HIH-4602-A/C is a combination of temperature sensor and RH sensor that is ideal for measuring dew point or other absolute humidity. The HIH-4602-A contains a thermistor, and the HIH-4602-C contains a precision RTD. Factory calibration data is provided for each sensor to achieve ±3.5%RH accuracy.
The HIH-4602-A/C series is a relative humidity sensor with integrated temperature compensation, designed for HVAC and industrial applications. It offers high accuracy (±3.5 %RH), low drift, and fast response in a TO‑5 package.
The document includes performance parameters, calibration data, NTC and RTD temperature‑sensor characteristics, typical output curves, mechanical dimensions, and recommended electrical connections for both the HIH-4602‑A and HIH-4602‑C variants. This manual is written in Chinese.
