Dewpoint Transmitters – XDT Series

General description

The dewpoint transmitters are designed as compact, simple and reliable instruments, which will continually monitor air dryer performance, compressed air quality and dry gas moisture, from ambient dewpoint levels to as low as  -100°C (-148°F).

Technical description

The HTF Aluminum Oxide sensor is the product of years of intensive research and has been thoroughly field proven. HTF technology offers significant performance advantages over all other aluminum oxide moisture sensors.

Due to a hyper-thin film and a special pore geometry, sensors have a capacitance change over their full range, several orders of magnitude larger than that of conventional aluminum oxide sensors. Additionally, this change is quasi linear and its sensitivity to temperature is negligible. The advantages of a linear high capacitance response are : better sensitivity, better repeatability and faster response time. Also, the measurement system is less prone to noise and drift, and signal conditioning is kept to a minimum.
