Oil Condition-Water Content Sensors
Presence of water in a hydraulic or lubrication system is detrimental to system operation as it tends to make oil acidic, hence its necessary that the same is measured and corrective action taken by effective filtration system.
Use of effective water content sensor enables the early detection of water break-in, thus avoiding malfunctions and damage to the system. Reduction in the costs of downtimes and repairs.
Water is present in an operating system either in free or dissolved manner and we offer sensors to measure these both.
The sensor for dissolved water measures the saturation level in percentage, independent of oil type, oil age and temperature - On line. The saturation level indicates what percentage of the maximum possible water quantity is dissolved in the oil. For this, 0% would mean water-free oil and 100% would mean oil which is completely saturated with water.
The sensor for free water measures water contents above the saturation point. It enables the continuous on line monitoring of the water content in percentages (approximately 0.5% to 50%). The signals are transmitted through an evaluator as 4 … 20 MA signals through an RS232 interface or as switching signals.
