Feb. 4, 2010 - PRLog -- Parker Hannifin, the global leader in motion and control technologies, has announced its MS300 in-line moisture sensor for hydraulic and lubricating systems has had its ATEX approval re-confirmed. Parker’s manufacturing processes have been found once again to comply with with BS EN 13980, allowing the MS300 to maintain its certification as Intrinsically Safe Electrical Apparatus. As a result, the device can continue to be used to provide fast, reliable and accurate moisture detection in hazardous applications for effective preventative maintenance.

The MS300 moisture sensor features the capabilities of Parker’s successful MS100 and MS200 models, with the ability to monitor and report Relative Humidity (RH) moisture content in oils, and making it easy for maintenance engineers to check if water contamination remains safely within the oil’s absorption range. The unit offers the additional option of programmable outputs to suit the needs of specific applications.

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.

The MS300’s renewed ATEX approval follows a successful annual visit by the auditor appointed by SIRA, confirming that Parker is authorised to continue to make and certify the MS300 4-20mA Current Loop Moisture Sensor to SIRA 07ATEX2255 and IECEx SIR 07.0089. SIRA is a world leader in the conformity assessment solutions field, specialising in explosion safety of equipment used in potentially explosive atmospheres (ATEX & IECEx). SIRA is accredited for these activities by the United Kingdom Accreditation Service (UKAS) and is appointed as a ‘notified body’ by the UK Government under European Directives.

The MS300 is part of Parker’s increasing range of products for hazardous areas, which also includes the ACM20 Z2 ATEX approved particle analyser, a proven solution for testing for contamination particles in fuel in explosive and hazardous areas, and the IcountPD Z2 particle detector for use in similar environments and applications, which will be launched globally later this year.
