Bourbon tube gauge |
Indicate pressure changes by its response to volume changes or to pressure changes |
|
|
Simplex bourdon tube gauge |
Simplex bourdon gauge are commonly used to measure fluid or gas pressure above atmospheric pressure such as steam pressure, water pressure, fuel pressure, oil pressure, and compressed air pressure |
|
|
Duplex bourdon tube gauge |
Measures to separate pressures at the same time, commonly used to measure the pressure drop ( pressure differential) across filters or strainers |
Two bourdon tubes and two separate gear mechanisms |
|
Vacuum bourdon tube gauge |
, use in a vacuum sewage system in air conditioning and refrigeration systems |
|
|
Compound bourdon tube gauge |
Commonly used to measure pressure is above atmospheric pressure and pressure is below atmospheric pressure (vacuum). They are collaborating using two different units of measurement, (PSIG) AND (HG) |
|
|
Differential bourdon tube gauge |
Measure the pressure drop ( pressure differential) across filters are strainers. Calibrated in pounds per square inch (psig or psi) |
Two bourdon tubes but only one pointer |
|
Liquid filled gauge |
Liquid within the gauge face protects a needle internal components from excessive vibration from the outside sources such as running in your rooms. Liquid also acts as a pressure snubber and prevent damage to engage from excessive pulsations from the system |
|
|
Pressure snubber |
Installation of pressure snubber Upstream of gauge will greatly reduce the magnitude of the pressure fluctuations (hydraulic shock). Damping or snapping actions occurs through metering fluid through this number |
Excessive wear to the drive mechanism, rapid pointer oscillation, possible premature failure to the gauge |
