Xentaur Mission Critical Dew Point Analyzer for Moisture Measurement
COSA Xentaur's mission critical dew point analyzer for moisture measurement is suitable for a variety of applications:
Using analyzer options, the measurement system is adaptable for every measurement challenge.
Taking advantage of the uniquely strong and quasi-linear response characteristics of its HTF™ aluminum oxide dew point sensors, Xentaur has developed a cost effective solution for demanding and mission critical moisture monitoring applications.
The system has an integrated, fully automatic self-calibration procedure, in which the sensor is periodically exposed to a NIST certified calibration gas and recalibrated. Thus, there can be high NIST traceable confidence in the measurement and sensors do not need to be returned to the factory for calibration.
The advantages of a linear high capacitance response are: better sensitivity, better repeatability and faster response times. Also, the measurement system is less prone to noise and drift, and signal conditioning is kept to a minimum.
This dew point system has proven to produce consistently accurate monitoring results for dew point in natural gas and other difficult hydrocarbon processing applications, where conventional analyzers have failed.
The model XDT uses a Xentaur HTF™ Aluminum Oxide sensor. The breakthrough HTF™ sensor technology represents advances in thin film and metal oxide sciences and offers significant performance advantages over all other aluminum oxide sensors.The operating principle of the HTF™ aluminum oxide sensors is that a hygroscopic layer of aluminum oxide adsorbs or releases water molecules within its pores, depending on the water vapor pressure in its environment. The electrical capacitance of the aluminum oxide layer changes with the surrounding water vapor pressure. The electrical capacitance is measured between the aluminum core of the sensor and a porous conductive gold layer on the outside.The advantages of the HTF sensor technology are a result of the proprietary manufacturing method in which the aluminum oxide layer is made to be hyper thin as well as extremely hygroscopic. This results in a very sensitive sensor with fast response.
