Dual Gauge Manifold Pressure Systems

Contact Instruments’ Dual Gauge Manifold Pressure System has become an industry standard due to its unique ability to detect the slightest change in low pressures and monitor low and high pressures without destroying the low pressure gauge.

By using a specially designed shut off valve we are able to direct low pressure (typically 1000 psi) to a low pressure gauge that makes the manifold pressure readings much more accurate. Once the pressure reaches the low pressure gauge maximum the pressure is then shut off to the low pressure gauge and directed to the high pressure gauge. The Dual Gauge Manifold Pressure system consists of two 6″ Simple Pressure gauges (one for low pressure readings and the other for high pressure readings), Contacts’ automatic pressure shut off valve (Pressures are set in our factory to correspond with pressures in the gauges ordered), CD106 Diaphragm Protector or CD136 Piston Isolator, 25′ High Pressure hose (other hose lengths available), Dual Gauge wall mounting bracket, Instrument Hand Pump and 1 Litre of All Weather Instrumentation fluid.
