Magnehelic Gauges

Magnehelic gauges use extremely high accuracy sensing elements to accurately measure low pressures. Using the simple friction-less Magnehelic movement, they quickly indicate low air or non-corrosive gas pressures - either positive, negative (vacuum) or differential. Widely used to measure fan and blower pressures, filter resistance, air velocity and clean room pressures. 

Magnehelic gauges are suitable for use in medical, HVAC and production applications. They are also suitable for incorporation into other machinery.

Gauges can be fitted with electrical contacts and analogue outputs for interfacing with other machinery or components. 

Magnehelic gauges are often used to measure differential pressure between clean and non-clean rooms in medical and production environments. We are able to supply all hoses and connections if required.

Magnehelics can be eith surface or panel mounted. We can also supply a range of wall brackets and enclosure to suit your application.

For complete clean room monitoring, GNW are able to build full control panels with Maghehelic gauges as local indicators, and other instrumentation to control other equipment such as fans, air conditioning units, door locks etc.
