Gauges

Pressure gauges measure the pressure of a fluid or gas relative to atmospheric pressure, while vacuum gauges measure pressures below atmospheric pressure.

The accuracy of a gauge depends on several factors, including the type of gauge, the quality of the materials and manufacturing process, and the conditions in which it is used. Higher-quality gauges with tighter tolerances will generally be more accurate.

Consider the type of fluid or gas being measured, the pressure range required, the size and location of the gauge, and any specific features or functions needed for your application.

A gauge isolator is a device that protects gauges from pressure spikes and pulsations in the system being measured. It works by separating the gauge from the process fluid with a diaphragm or piston, allowing the gauge to respond to changes in pressure without being damaged.

Mechanical gauges use a physical mechanism, such as a bourdon tube or diaphragm, to measure pressure or vacuum. Electronic gauges use sensors and digital readouts to provide more precise and consistent measurements.

A temperature gauge measures the temperature of a fluid or gas. It works by using a bimetallic strip or other mechanism to convert changes in temperature into mechanical movement, which is then displayed on a dial or digital readout.

Gauges can be calibrated using a reference gauge or a calibration standard. Follow the manufacturer’s instructions for your specific gauge and use the appropriate tools and procedures to ensure accurate calibration.

The operating range of a gauge refers to the range of pressures or temperatures that the gauge can accurately measure. Consult the manufacturer’s specifications to determine the operating range of your gauge.
