About the Diaphragm Pressure Gauge

These pressure gauges use mechanical principles with axles to transfer pressure from the diaphragm through to the movement. To this end, the gauge is suitable for all liquid and gaseous media, suspended solids and other viscous media.

Purpose

Basically, the diaphragm pressure gauge you will buy from Viking Instrument and Control LTD can be used to measure pressure in fluids. You can also use it to record the strength of vacuum in vacuum pumps, measure atmospheric pressure, and monitor pressure in a gas canister among others.

Basic Mechanics

The basic diaphragm pressure gauge from Viking Instrument and Control LTD has flexible membranes with 2 sides. One side contains an enclosed capsule with air or another fluid with a predetermined pressure while the other side is either screwed in to the system to be measured or left open. The diaphragm is also attached to a meter showing how high the pressure gets.

Detecting Pressure

To measure pressure, a fluid pushes and bends the flexible membrane. Pressure is measured by how hard the fluid pushes the membrane. If the outside preference is low, then the reference pressure will bend out the membrane. With an increase in outside pressure, the membrane will be pushed back and bended the other way. When you measure how far the membrane was bent, the gauge can be used to detect outside pressure.

Measuring Pressure

Using the dynamic pressure gauge from Viking Instrument and Control LTD, you can measure pressure in a number of different ways. The simplest of these is to connect the gauge to a needle. With a pressure increase, the needle will be pushed and moved up and down the dial, showing the pressure.

The other way involves using an electric resistant strain gauge. This uses an electric resistor strip (which resists electric flow) attached to the diaphragm. When the diaphragm bends, it will stretch the resistor out, thereby increasing resistance.

An electric current runs through the resistor. An increase in resistance and diaphragm bending causes the current to drop. When you measure the electric current, the diaphragm pressure gauge will measure the extent to which the diaphragm has bent and the amount of pressure created by outside air.
