ATEX approved moisture sensor

02 March 2009

Parker Hannifin has launched an ATEX approved version of its proven in-line moisture sensor for hydraulic and lubricating systems. The MS300 has been certified as Intrinsically Safe Electrical Apparatus and offers, fast, reliable and accurate moisture detection in hazardous applications for effective preventative maintenance.

The latest MS300 and MS200 moisture sensors have the ability to monitor and report Relative Humidity (RH) moisture content in oils, and make it easy to check if water contamination remains safely within the oil’s absorption range.

The ATEX approved MS300 model is designed for use with category 1G equipment and can be used with galvanic isolators within specified electrical parameters. The MS300 can also be used in Zone 0 hazardous areas and potentially explosive atmospheres, where moisture sensors are typically not allowed without permits.

Both sensors have four main output options of 0 to 3 Volts, 0 to 5 Volts, 1 to 6 Volts or 4-20mA, plus the addition of temperature. Other outputs can be programmed to meet individual user requirements.
