Gauge pressure is zero-referenced against ambient air pressure, so it is equal to absolute pressure minus atmospheric pressure. MANIFOLD GAUGE PLUS
Absolute pressure is zero-referenced against a perfect vacuum, using an absolute scale, so it is equal to gauge pressure plus atmospheric pressure. When distinguishing between these zero references, the following terms are used: In other cases measurements are made relative to a vacuum or to some other specific reference. Other methods of pressure measurement involve sensors that can transmit the pressure reading to a remote indicator or control system ( telemetry).Įveryday pressure measurements, such as for vehicle tire pressure, are usually made relative to ambient air pressure. For very low pressures, a gauge that uses total vacuum as the zero point reference must be used, giving pressure reading as an absolute pressure. However, anything greater than total vacuum is technically a form of pressure. Most gauges measure pressure relative to atmospheric pressure as the zero point, so this form of reading is simply referred to as "gauge pressure". The widely used Bourdon gauge is a mechanical device, which both measures and indicates and is probably the best known type of gauge.Ī vacuum gauge is used to measure pressures lower than the ambient atmospheric pressure, which is set as the zero point, in negative values (for instance, −1 bar or −760 mmHg equals total vacuum). Instruments used to measure and display pressure mechanically are called pressure gauges, vacuum gauges or compound gauges (vacuum & pressure). Many techniques have been developed for the measurement of pressure and vacuum. Pressure is typically measured in units of force per unit of surface area. Pressure measurement is the measurement of an applied force by a fluid ( liquid or gas) on a surface. Visit fieldpiece.Checking tire pressure with a spring and piston tire-pressure gauge 
If you are looking for a manifold gauge, Fieldpiece can help. Additional features such as data logging and strategically placed thermocouple ports are beneficial. When deciding on a manifold gauge to buy, it is important to ensure the manifold gauge is designed to withstand the rigors of field use including heavy duty casing, reinforced hook, water resistance, and impact resistant screen.

Many digital gauges now have Bluetooth built-in for connecting to smartphones. The gauge can be either analog or digital. There are different types of manifold gauges and often a HVACR technician may have multiple sets depending on the type of jobs they have. A HVACR manifold gauge can be used for many different functions such as checking pressure, adding refrigerant, and determining if there is a leak. It is a necessary tool in order to diagnose if the system is correctly charged with refrigerant as well as to help service any issues. An important tool that you will need is a HVACR manifold gauge.Ī manifold gauge is used to check the pressure of refrigerants in HVACR systems.
There are a lot of working parts in a HVACR system that needs to be checked out regularly for maintenance.
