Differential Pressure Gauge Calibration
Differential pressure gauges are used to measure the difference in applied pressure of two separate environments. They act as a visual monitor for operators to determine values using a single gauge, rather than relying on a comparison of multiple gauges which independently measure pressure.
There are a variety of differential gauge types, which are used based on the requirements of the application. For example, manometers use a U-shaped tube filled with liquid which measures pressured applied at either end. These are frequently used on fume hoods or paint booths where a constant negative pressure is required for operator safety.
Other gauges measure pressure from similar duel inlets in the gauge, however, utilizing transducers or pressure points rather than a visual gauge. These are frequently used in scenarios with liquid or gas stored in tanks or moving through lines.
Some types of differential gauges even utilize a magnet positioned on the inside of the gauge next to a metal spiral. As the magnet is moved by incoming air pressure, the spiral rotates to follow it, moving the needle of the gauge along its face.
Using NIST traceable master standards, Cross offers differential pressure gauge calibration for a wide range of pressure levels on a variety of types and models. So no matter which type of gauge you are using, Cross can help to ensure your systems are operating correctly, and that your operators are safe.
