Instruments For Moisture

Xentaur Products 

XENTAUR Corporation is a popular name in the field of Moisture Analysis. XENTAUR developed HTF technology which is significantly different from the conventional technology.

The main technology differences are a hyper-thin oxide layer, a well-defined barrier layer and a pore geometry that can arrest the Brownian motion of water molecules. These characteristics result in the following superior features:

1. A three-hundred (300)times larger sensitivity to moisture compared to conventional aluminum oxide sensors.
2. Long-term stability of HTF™ sensors, meaning the elimination of the ageing drift that is inherent with conventional aluminum oxide sensors.
3. A negligible temperature coefficient over the full range.
4. A strong resistance to corrosive substances and other contaminants.

The main advantages of HTF™ sensors in mechanical construction are:-

1. The only materials exposed to the sample are gold and aluminum oxide, a ceramic. Neither reacts chemically with the contaminants typically found in natural  gas  samples.  By  contrast,  conventional sensors expose aluminum, which rapidly corrodes in  the  presence  of  most  corrosive  substances including those found in natural gas samples.
2. Only one electrode is exposed to the sample, pre-venting sensor shorting. By contrast, conventional aluminum oxide sensors expose both electrodes to the sample, which leads to sensors shorting when the sensor gets in contact with conductive materials, such as for example wet glycol, which is typically present in natural gas.

One of the main improvement of HTF™ sensors over conventional sensors is that  HTF™ sensors do not suffer from calibration drift, which is associated with conventional aluminum oxide sensors. The calibration drift of conventional aluminum oxide sensors is the result of metal migration (layer growth) and a gradual relapse of the hygroscopic aluminum oxide structures created by the manufacturer into the non-hygroscopic natural aluminum oxide structure.

With HTF™ sensors, metal migration and the resulting layer growth has been eliminated by a well defined barrier layer. Furthermore,  HTF™ sensors do not rely on hygroscopic aluminum oxide structures, but on a special pore geometry, which is stable. As a result,  HTF™ sensors do not need frequent re-calibration like conventional sensors need.

Self-Calibration system eliminates any drift. Field calibration feature is not available with reputed conventional aluminum oxide sensors technology manufacturers who are present in the market and their sensor needs to be returned to their factory every 6 to 8 months, depending upon application which leads to several issues like down time, to keep "recently calibrated" spare sensor ready in the inventory etc.

Xentaur product range includes Online Dew Point Meters and Transmitters, Process Analyzers and Portable Hand Held Instruments for Moisture measurements.

HTF™ Sensors are rugged and specially well suited for tough applications HTF™ technology is field proven in hundreds of different applications in thousands of installations world wide.
