The direct measurement of water vapor pressure is accomplished easily and effectively in both gases and liquids by the M Series aluminium oxide moisture sensor.
M Series probes are designed to be located at the process, exactly where the measurement is needed. Cable length between the probe and hygrometer may be 2000 ft (610 m) or more. Pressure range is from vacuum up to 5000 psig (345 bar) with no minimum flow requirements. Sample cells make M Series probes easy to install, and the cells are available in general purpose, Type 4 weatherproof, and Type 7 explosion-proof housings.
Remote installation of the probe and wide operating parameters minimize measurement lag time and the potential for sample contamination associated with long sample runs back to an analyser. This feature is extremely important in the measurement of very low moisture content or where rapid changes occur.
