HIH-4602-A/C Series Humidity Sensors
The HIH-4602-A/C Series Relative Humidity (RH) sensors integrate both relative humidity and temperature sensing within a TO-5 housing, featuring a hydrophobic sintered stainless steel filter. These sensors utilize laser-trimmed, thermoset polymer capacitive sensing elements with on-chip signal conditioning. The temperature sensor is thermally coupled with the RH sensor, making the HIH-4602-A/C series ideal for measuring dew point and other absolute moisture terms. The HIH-4602-A includes an integral thermistor, while the HIH-4602-C incorporates an integral precision RTD. Factory calibration data provided with each sensor enables individually matched downstream electronics and 3.5%RH total accuracy. Key advantages include near linear voltage output, laser-trimmed interchangeability, enhanced accuracy, fast response, chemical resistance, stable low drift performance, built-in static protection, and suitability for dew point and absolute moisture measurements. Potential applications span refrigeration, drying, meteorology, battery-powered systems, and OEM assemblies.
