You probably already know that free and emulsified water cause problems. But, did you know that water can increase the oxidation rate of your lubricant by more than ten times? That’s why your oil analysis service includes a water-screening test.  Were you aware that bearings could lose 75% of their potential service life due to water before the oil even begins to start to look cloudy? Even in its dissolved state the water is at work, attacking the base stock, the additive package, and the machine. And, water can carry organisms with it that could disable your critical hydraulic systems.

The Moisture range of online sensors puts your oil analysis laboratory on your doorstep telling you exactly how dry your oil is.  Providing % Relative Humidity (RH) and temperature values you can ensure that your oil is always below the saturation point before free and emulsified water starts to form.  The sensor measures the oils percentage Relative Humidity, resulting from the dissolved water within the lubricant, using a combination of proven thin film capacitance sensors, combined with smart algorithms to provide a temperature and % RH value.

Using internal processing power the self diagnostic sensor does not require handheld units to analyse or display results. It can be easily integrated into your existing Condition Monitoring and operating control systems, and results can be reported using standard displays or any PC.  Whether it’s to check on the health of the machine, or an alert of changing moisture ingression rates, the Moisture Sensor from Kittiwake provides instant information, complementing your existing laboratory oil analysis programme, and helping you make informed maintenance planning decisions.

Features Include:
  • Seperate head and sensor body for increased accuracy and reliablility
  • High integrity sealing using standard automotive techniques
  • Smart sensor with internal processing power offers wide interface options
  • Stainless steel housing - Rugged and long life performance
  • Widely used ½” BSP thread - Quick and easy installation to a wide range of machinery
 
The requirement for on-line machinery and oil condition monitoring is becoming evermore apparent as maintenance costs increase and production capacity and equipment performance is maximised.


While temperature, pressure and vibration sensors all have their part to play in a condition monitoring package, early detection of changes in oil and lubricant condition and regular, consistent monitoring of wear metal debris in rotating plant provide greater insight into the actual condition of vital machinery and equipment.

Kittiwake have developed a range of innovative and practical on-line sensors for wear metal debris and oil condition detection and monitoring.

The ANALEXrs range is designed to provide plant engineers and maintenance managers with real time, continuously monitored testing and analysis data for critical plant and equipment.

Suitable for use with slow, medium and high speed diesel engines, gas turbines, gearboxes, compressors, generators, vehicles and other oil filled plant, these sensors help to increase productivity, reduce costs and improve profitability.
