Well, darling, pressure gauges don't give a hoot about altitude when it comes to calibration. They just want to be accurate wherever they are. So yes, pressure gauges do need to be calibrated for altitude because atmospheric pressure changes with altitude, and if you want reliable readings, you better make sure that gauge is properly calibrated.
yes for every 5000 feet of elevation your bourdon tube type of gauge will increase by 2 psi. even though the sealed vessel you are checking remains at the same psi.
example if i have a sealed tank at sea level and it is reading 12 psi. at 5000 feet the same tank and gauge will now read 14 psi. and at 10000 feet 16 psi. the tank pressure has not changed but the gauge is now out of whack because there is less pressure pressing on the bourdon tube. less atmospheric pressure easier for the gauge to go up.

What does a compound pressure gauge measure in?
A compound pressure gauge measures both positive and negative pressure in a system. Positive pressure is the pressure above atmospheric pressure, while negative pressure is the pressure below atmospheric pressure. This type of gauge is commonly used in applications where both types of pressure need to be monitored, such as in HVAC systems or industrial processes.
How many bar of pressure to lift 1 ton?
To lift 1 ton (equal to 2,000 pounds) with a hydraulic system, you would need to apply 2,000 pounds of force. Since pressure is force divided by area, and the area of a typical hydraulic cylinder is around 1 square inch, you would need 2,000 pounds per square inch (psi) of pressure to lift 1 ton. In other words, you would need a hydraulic system capable of generating 2,000 psi to lift 1 ton.
How do you Convert pounds of chlorine to gallon?
You need to know the density of the chlorine which is affected by the temperature and pressure at which the chlorine is. Once you know the density, you can convert it using: density = mass/volume → volume = mass/density. You'll need to know the density in pounds per gallon.
What is the compression ratio of 600 PSI?
"600 psi" is not a compression ratio; it's a pressure. For a RATIO, you need to compare TWO different numbers.
What measures the pressure of a gas or vapor?
Gas pressure can be measured using several different instruments including:Hydrostatic gauges - like a manometer or barometerPiston gauges - like tire pressure gaugesMechanical gauges - which use deflection of diaphragm, a capsule, or a set of bellows, which will change shape in response to the pressure of the region in questionBourdon tube - a type of mechanical gauge that uses a coiled tube (Bourdon tube) that deflects with pressureElectronic - including:Piezo resistive Strain GageCapacitiveMagneticPiezoelectricOpticalPotentiometricResonantThermal conductivity (conductivity of gasses changes with density - has to be calibrated to the gas)Ionization (best for low pressure gases - has to be calibrated to the gas)
Why don't your fuel battery coolant and oil pressure gauges on your 88' ford work?

Does the pressure dial indicator on a air compressor need to be calibrated?
Almost anything involving compressed air with a dial indicator would need to be calibrated or checked once in awhile. Pressure at the magnitude could be very harmful if not properly handled by someone who knows what they are doing.
How do you calibrate an oil pressure gauge?
you need to check it against another gauge that is accurate which should be calibrated by a pressure calibration lab. So at least you know that the gauge you use to test your oil gauge is right. Then just "tee" in the "master" gauge into your oil line and check the two gauges against each other when the engine is running.
What are air brake gauges for?
Most air brake systems are fail-safe. This means that if there is a failure in the pressure system the brakes will lock on. You need gauges to show that you have sufficient pressure to proceed and to know your brakes are not dragging as this would cause them to overheat.
When evacuating a refrigeration system what is the easiest way to tell if all the liquid refrigerant has left the system?
What you need to do first is read the pressure gauges and see if the gauges read 0 psi
Do you need to increase the cooling system relief valve setting at altitude to compensate for lower atmospheric pressure?
no, but check your tire pressure
How do you calibrate compound gauges?
To calibrate compound gauges, you will need a calibration pump and a pressure calibrator. Connect the compound gauge to the calibration pump and apply pressure using the pressure calibrator. Compare the readings on the compound gauge with the readings on the pressure calibrator and make necessary adjustments to bring them into alignment.
Does a wheel alignment machine needs to be calibrated?
Yes, wheel alignment machines do need to be calibrated.
Why Celsius scale is calibrated?
Scales that aren't calibrated are unreliable.
How do you see if a 2008 Town and Country Touring mini vans air condition needs freon?
You need a set of pressure gauges to hook up.
Where can one purchase a spare water pressure gauge?
Water pressure gauges can be purchased at all of the home improvement stores. Home Depot, Lowe's, and Berry Home Centers all carry them. Walmart even has them on their website.
