180 Differential Gauge

180 Microvar Differential Gauge Budenberg Australia @ Procon Instrument Technology

Micravor Diaphragm type Differential Pressure Gauge

The Budenberg model 180 differential pressure gauges have been 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.

The 180 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.

The Budenberg Micravor Gauges can be used for a number of applications including:

  1. Liquids use the 180A or 180B
  2. Gases use the 180AM or 180AB (not for oxygen)

Equalising Valves Budenberg recoomends the use of needle type isolating or equalising valves for use with this instrument, as quick operating valves can cause harmful pressure surges.
Snubbers If pressure surges or fluctuations cannont be eliminated we can offer guages with an internal snubber which gives a delay of up to 20 seconds.
