Alerton Humidity Sensors
Alerton/ACI Relative Humidity Sensors utilizes a thermoset polymer capacitive sensing element with a factory fitted hydrophobic filter to improve its moisture resistance.
Overview
Alerton/ACI Relative Humidity Sensors utilizes a thermoset polymer capacitive sensing element with a factory fitted hydrophobic filter to improve its moisture. The Humidity Transmitters utitilize a capacitive sensing element to deliver a proportional analog output. This series features on board DIP Switches which allow user to select the desired output signal. In addition, field calibration can be performed by using the on board increment and decrement DIP switches. These enhancements provide increased flexibility and outstanding long term performance. Duct and outside air configurations feature conformally coated circuit boards for moisture resistance. Several RTD and Temperature sensing elements are available in this seriesCertifications:
- CE, ROHS
