Pressure Indicator is any instrument that indicates pressure. Pressure Gauge is also a type of pressure Indicator. It is a mechanical device. Pressure indicators can work on mechanical deflection (in case of pressure gauge) or Piezo electric effect, change in capacitance, change in inductance etc. These are generally digital type instruments.

What is the difference between normal pressure gauge and differential pressure gauge?
A pressure gauge indicates actual pressure and a differential pressure gauge indicates the difference in pressure.
What are you measuring when you measure air preasure?
The difference in pressure between absolute and gauge pressure.
What does a compound pressure gauge measure in?
The Compound Gauge measures above and below atmospheric pressure (in psig and inches of mercury).
How do you protect a pressure gauge from pressure surges?
a sertain way
100 mm WG equals?
mmWG is a pressure unit. its something like mm Hg, however in mmWG, W refers to water and G refers to gauge pressure. Hence, mm WG refers to the gauge pressure in terms of milimeters of water.
What is the difference between normal pressure gauge and differential pressure gauge?
A pressure gauge indicates actual pressure and a differential pressure gauge indicates the difference in pressure.
What are you measuring when you measure air preasure?
The difference in pressure between absolute and gauge pressure.
Is gauge pressure is the sum of true pressure and atmospheric pressure?
No, it is the DIFFERENCE between the true and atmospheric pressures.
Can you see the difference between a wet and a dry standpipe system?
Yes you can. A dry standpipe system has an air pressure and a water gauge the air pressure gauge is normally found on the top or the (pressure side) the water gauge is normally located on the bottom under the air pressure gauge or the (supply side)
What is micro manometer?
A manometer is a pressure gauge. A micro manometer is either a really small pressure gauge, or a pressure gauge used to measure really small pressure difference.
Difference between pressure gauge and vacuum gauge?
A pressure gauge measures the pressure of a fluid or gas relative to atmospheric pressure, while a vacuum gauge measures pressures below atmospheric pressure. Pressure gauges typically have a positive scale, while vacuum gauges have a negative scale. Both gauges provide crucial information for monitoring and controlling pressure systems.
What gauge measures both vacuum and pressure?
Gauge pressure usually refers to the pressure difference between ambient, atmospheric pressure and the pressure in a vessel or line. A gauge pressure of zero would mean that the vessel or line was at atmospheric pressure. Normally the pressures of interest are ABOVE atmospheric so the gauge pressure is positive. Vacuum gauge pressure measures how far BELOW atmospheric pressure a vessel or line is. As such vacuum gauge pressure may be measured as a negative number - or for convenience it may be reported as a positive number with the caveat that it is "vacuum gauge pressure", meaning that the reported pressure is how far atmospheric pressure is above the pressure in the vessel or line.
What is a oil sending switch?
This is a pressure sensitive switch that controls the oil pressure indicator (light or gauge) on the dash board in the vehicle
Water pressure can be measured in PSI is ther any other way?
Yes, there are many ways to measure pressure. * pascal (Pa) * bar * technical atmosphere (at) * atmosphere (atm) * torr (Torr) * pound-force per square inch (psi) * psia (pounds-force per square inch absolute) --- gauge pressure plus local atmospheric pressure. * psid (psi difference) --- difference between two pressures. * psig (pounds-force per square inch gauge). * psivg (psi vented gauge) --- difference between the measuring point and the local pressure. * psisg (psi sealed gauge) --- difference between a chamber of air sealed at atmospheric pressure and the pressure at the measuring point. Check out the links for MUCH more information.
If the absolute pressure of gas is 550.280 kPa it's gage pressure is?
The gauge pressure is the difference between the absolute pressure and atmospheric pressure. If atmospheric pressure is approximately 101.3 kPa, then the gauge pressure would be 448.980 kPa (550.280 kPa - 101.3 kPa).
How many gauge glasses on large boiler?
Steam would have a gauge 0-15 Hot water Tri indicator Temperature /pressure /altitude
What is a oil sending unit switch?
This is a pressure sensitive switch that controls the oil pressure indicator (light or gauge) on the dash board in the vehicle
