Pressure gauge calibration
Barometer calibration is one of the simplest calibration methods. Barometers are pressure gauges that typically consist of pressure gauges made of Bourdon tubes as pressure gauges.
There are different types of barometers based on different products, so calibration methods also change. Let’s look at some calibration methods.
-
Adjust the button at the bottom of the barometer
Just remove the lock and calibrate the pressure gauge.
-
Adjust the screw in the pressure gauge mechanism.
Some manufacturers provide a calibration screw on the gauge plate (as shown in the figure below. Close to the pointer) to adjust the screw for calibration.
-
Adjust the screw on the gauge needle marker itself.
Some manufacturers of pressure gauges offer calibration screws on the indicator. Adjust the screw for calibration.
-
Open the pressure relief glass (or plastic cover) and then remove the needle.
5. Open the pressure gauge to calibrate and set zero and spam. Opening the Glass by Craftsman 2 pc 16 ”Rubber Strap Wrench Using the marker pull, pull the marker and adjust the spam pressure by applying pressure by the hand pump or any other device.
The main method of calibrating the pressure gauge
- Connect the equipment specifications for pressure calibration as shown above.
- Apply pressure 0. (zero setting)
- Adjust the zero screw or set the indicator to 0.
- Apply 100% pressure (opening adjustment)
- To correct the sign, the arm of the section is increased or decreased
- Apply pressure ٪ 50 (linear adjustment)
- Adjust the length of the link or use the link to drag the pointer and place it in the correct spot.
- Check the results at 0%, 25%, 50%, 70% and 100%.
- Repeat these steps to get the correct values.
