Oil Filled Air Pressure Gauge. I beleive the compass oil is the same oil [mineral] as supplied for vacuum pumps. i just filled some pumps after service and it was the same spec oil. its clear btw. not like ordinary oil. i asked one of the fitters what was in the damped gauges as a damping fluid and he thought it was silicone oil but it turns out its the same spec as the vacuum oil i use. needless to say there. Low failure rate means less money spent purchasing replacements.

Oil filled gauge helps reduce pointer vibration eliminates corrosion resulting from condensed water when installed in a high humid area applicable for the working environment with strong pulse and large. In today’s more demanding environment. instruments in the oil. natural gas. and chemical industries and processing plants must work under such. If you do decide to refill. dont fill it completely up. leave a small air bubble. as glycerine will expand contract due to temp.

For Use With Oil. Water Or Any Other Liquid Which Will Not Attack Brass Or Bronze. Also Suitable For Air Or Inert Gases Below 25 Bar (Excluding Oxygen Or Acetylene).
Liquid filled pressure gauges available at compressed air systems. Also. because they are built to be durable. you can count on them to last long into the future. The liquid fill lubricates all moving components. dramatically reducing wear of.
Polyconn Offers Pressure Gauges In A Wide Selection Of Pressure Ranges And Case Sizes.
Liquid filling of pressure gauges. Air venturi pressure gauge (manometer) reads up to 6.000 psi and 400 bar; The liquid coats the internal parts and is visible on the gauges face.
The Liquid Fill Dampens Vibration. Mechanical Shock. And Pressure Pulsations. Enabling Easier Pressure Readings.
Pressure build up inside a gauge can happen and is very natural for a liquid filled gauge. The difference between glycerine filled pressure gauge and silicone filled pressure gauge. Its transmission indicating mechanism is a viscous damping fluid. which greatly reduces the impact of mechanical vibration on its work.
