Product Specification

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.

    The HIH-4602-A contains an integral thermistor, while the HIH-4602-C contains an integral precision RTD.

Specific Notes:

1. Device is calibrated at 5 Vdc and 25 ºC.

2. Non-condensing environment.

 

General Notes:

Sensor is ratiometric to supply voltage.

Extended exposure to >90% RH causes a reversible shift of 3% RH.

Sensor is light sensitive. For best performance, shield sensor from bright light.
