July 27, 2017 – Servomex has launched the AquaXact 1688: a moisture sensor that can be used as a standalone 4-20mA loop-powered device, or digitally interfaced to Servomex’s AquaXact control unit, SERVOPRO MonoExact DF310E oxygen analyzer or forthcoming SERVOPRO MultiExact 4100 multi-gas analyzer.
Using a film technology Aluminum Oxide replaceable sensor element, the AquaXact 1688 enables dew point and ppm H2O measurements in various process applications, including glove boxes, air separation units, natural gas processing and instrument air.
The sensor tip is user-replaceable, using any of the controller options to load the associated calibration file.
Because it has been designed to complement the next generation of Servomex industrial gas analyzers that includes the MonoExact DF310E and MultiExact 4100, the AquaXact has the option of integrating with the products via a remote digital interface. The color, icon-driven 5” touchscreen display offered by these analyzers enables navigation of the software features; a dedicated AquaXact 1688 digital controller, also using the color touchscreen, is also available.
Housed in a stainless steel, weatherproof casing (which is IP65/NEMA4x certified) the AquaXact 1688 operates in ambient temperatures ranging from -10oC to +70oC. With a dew point range from -100oC to +20oC (ppmv ranges are also available), the sensor offers an accuracy of ±3oC and repeatability within 0.5oC.
