Amphenol Advanced Sensors’ T9501 harsh environment RH and Temperature sensor is built around the Telaire ChipCap 2, which is a capacitive polymer sensor chip with an integrated PTA temperature sensor. The ChipCap2 is overmolded in an IP67-rated housing to create the T9501. The T9501 is fully calibrated and temperature-compensated allowing for a highly accurate RH and Temperature sensor with a long-term drift (under normal conditions) of <0.5% RH/year. The T9501 has an accuracy rating of ±2.0% in the 20% - 80% operating range. The complete outline of RH specifications are shown in the included table and graph.
