Budenberg 180 Microvar Diaphragm Type Differential Pressure Gauge

Product Description

The Budenberg 180 Microvar Diaphragm Type Differential Pressure Gauge is manufactured with a stainless steel diaphragm as the measuring element, the strength of which depends on the differential pressure graduation. The element is isolated from the pressure by two Melinex diaphragms so that only clean oil fills the chamber in which the mechanism operates. Melinex is a polyester film (polyethylene terephtalate) that is resistant to all petroleum refining industry fluids. Please consult our technical department to check suitability for other chemicals. This instrument is generally used in applications where the system pressure is very much higher than differential range and can be used for measuring differential pressure in filters , strainers, coolers, pumps, natural gas strainers, orifice plates and venturi tubes. We have an interesting article relating to Pressure Gauge Selection in the Technical section on this website.

Designed and manufactured in the UK.
