Application of HMT310
Reliable Vaisala HUMICAP® Technology
The HMT310 incorporates the latest generation Vaisala HUMICAP® Sensor.
The Vaisala HUMICAP® Sensor is a capacitive thin-film polymer sensor.
It features high accuracy, excellent long-term stability and negligible hysteresis.
It is insensitive to dust, particulate dirt and most chemicals.
Several Outputs, One Connector
The HMT310 is powered up with 12 ... 35 VDC. It has two analog outputs and an RS-232 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 calibraton intervals and it involves heating the sensor to remove harmful chemicals.
The function can be initiated manually or programmed to occur at set intervals.
