Relative Humidity Moisture Transmitters

Panametrics relative humidity transmitters use a proven polymer capacitive sensor to provide a humidity measurement in the range of 0 to 100% RH. The sensor consists of a hygroscopic polymer sensing layer whose dielectric properties change depending on the amount of water vapor in contact with the sensing surface. This causes a change in the capacitance of the sensor which is then converted into a relative humidity reading. 

Benefits: 

• Good resistance to chemical vapors
• Ability to function at high temperatures (>100 °C)
• Fast speed of response
• Ability to recover from condensation or full water immersion
