Vaisala The HMT310 incorporates the latest generation Vaisala HUMICAP sensor. The sensor is a capacitive thin-film polymer sensor providing high accuracy, excellent long-term stability and negligible hysteresis.
♦ Accuracy ±1
♦ Latest generation Vaisala HUMICAP® sensor for excellent accuracy and stability
♦ Full 0 ... 100 %RH measurement, temperature range up to +180 °C (+356 °F),
depending on model
♦ Small size, easy to integrate
♦ Insensitive to dust and most chemicals
♦ NIST traceable calibration (certificate included)
The HMT310 is powered up with 10 ... 35 VDC. It has two analog outputs and an RS232 serial output. The output signal and the supply power travel in the same cable, the only cable connected to the unit.
Chemical purge helps to maintain measurement accuracy between calibration intervals. It involves heating the sensor to remove harmful chemicals. The function can be initiated manually or programmed to occur at set intervals.
