T9501 Harsh-Environment Temperature and Humidity Sensor

Amphenol Advanced Sensors' IP67-rated Modbus digital-output temperature and humidity sensor

Image of Amphenol Advanced Sensors' T9501 Harsh-Environment Temp and Humidity SensorAmphenol Advanced Sensors’ T9501 harsh-environment temperature and humidity sensor is IP67-rated, meaning that is completely protected against the ingress of dust and airborne particles, as well as water and liquids, up to and including immersion in up to one meter of water. The design is based on Amphenol Advanced Sensors’ capacitive polymer sensor chip and ASIC, integrated into an easy-mount OEM package as two external mounting tabs are molded into the sensor’s enclosure and can be easily attached utilizing two #10/M5 bolts/screws (or equivalent). The T9501 measures temperature utilizing an onboard proportional-to-absolute temperature sensor.

Each sensor is individually calibrated and tested at the factory prior to shipping. As a result, the T9501 arrives ready to install without further calibration or temperature compensation.

The T9501 is rated for operating conditions of -30°C to + 70°C and 0% to 100% relative humidity (non-condensing). The temperature and humidity sensor is precise and accurate and is rated for ±2% RH at 20% to 80% and ±0.5°C temperature accuracy at 14 bits. The sensor is provided with varying lengths of cable (depending on the model number, refer to the ordering information for more details) and a Deutsch sensor connector housing is standard. The sensor output is Modbus digital RS485-configurable, with a 115,200 baud-rate (with fault-protection). The sensor is powered with an 8 VDC to 32 VDC (12 VDC) power supply with polarity protection. The sensor has a low-power consumption of <10 mA average when in bus Rx-mode, and peaks at 70 mA when in bus Rx-mode/heat. And, the T9501 is provided with a 12-month factory warranty.
