This is the same system incorporated in our popular low-pressure membrane dehydrators. Here, it is a stand-alone device, usable independently or downstream of an air dehydrator whose built-in monitor/alarm system is unreliable or obsolete.
The highly-sensitive aluminum oxide sensor is bathed by a continuous stream of air. Its impedance varies with the air’s moisture content, and is read by the dew point alarm controller. The digital display on the front shows the current outlet air dew point.
- A simple, reliable method of measuring the dew point (moisture content) of low-pressure (0 – 150 psig) dry air systems.
- Measurement made by aluminum oxide sensor.
