Amphenol Advanced Sensors’ T9501 harsh environment RH and Temperature sensor includes a proportional to absolute (PTA) integrated temperature sensor. It has an accuracy rating of ±0.5°C with a ±0.1°C repeatability. The PTA temperature sensor has a response time of ≤600 seconds (63%) with an anticipated long-term drift (under normal conditions) of <0.05°C/year. The complete outline of temperature specifications are shown in the included table and graph.
