New real time moisture sensor for condition monitoring in hydraulic and lubricating systems
Keywords: Lubrication, Sensors, Moisture
Parker Filter Division Europe has announced the introduction of the new MS100 moisture sensor that provides a compact, real time solution to continuous water contamination condition monitoring in hydraulic and lubricating systems used throughout manufacturing industry (Plate 5).
Water enters hydraulic and lubricating systems from a variety of sources: atmospheric ingression of water vapour, as well as internal heat exchanger leaks, thus creating unfavourable operating conditions. The Parker MS100 moisture sensor will operate with petroleum/synthetic hydraulic and lubricating oil and, in addition, a phosphate ester version can also be specified. It has been designed to provide real time, accurate and repeatable results reported as percent saturation of water.

Percent saturation is a useful measurement that offers the user a simple, quantitative method of determining how wet or dry an hydraulic or lubricating system may be.
In contrast, PPM and percent water by volume measurements provided little information about fluids free or dissolved water condition. However, percent Saturation can be converted to PPM as long as the fluid's saturation point is known at the system operating temperature.
Available from Parker's dedicated Condition Monitoring Centre in Thetford, the MS100 moisture sensor is designed for maximum operating pressure of 420 bar (6,000 psi), measures just 106 mm long by 50 mm diameter, and will operate at temperatures from -40 to 85°C (-40 to 185°F). Input supply voltage is 8-30 V dc.
Simple LEDs provide local Go/No-Go indication. A blue LED will indicate when the oil's water concentration reaches >80 per cent saturation (end-user adjustable) and trigger a corresponding voltage output. The unit also features an analogue output proportional to per cent saturation with a dynamic range of 0.85-4.05 V. An optional indicator display is available for local or remote display reports of 0-100 per cent saturation.
