1. What is the measuring range of this gauge?

It has a measuring range of 0 to 300 psi (pound-force per square inch.

2. What are the advantages of Stainless Steel 304?

Stainless steel 304 has good corrosion and vibration resistance and is suitable for a wide range of industrial environments.

3. What does radial connection mean?

Radial connection means that the connection interface of the pressure gauge is perpendicular to the dial.

4. What is the accuracy grade?

The accuracy level is usually ±1.0%, ±1.6%, ±2.5%, etc. The specific accuracy level may vary from product to product.

5. What is the ambient temperature?

Generally speaking, the ambient temperature range is from -40℃ to 70℃ (with liquid in the shell) or -25℃ to 70℃ (without liquid in the shell.

6. How do I select a pressure measurement point?

When selecting the pressure measurement point, the following points should be noted: to be selected in the measured medium straight flow of the pipe section part, do not choose in the pipeline corner, bifurcation, dead end or other easy to form a vortex; measurement of the pressure of the flowing medium, the pressure point should be perpendicular to the direction of flow, to remove the drilling burr; measurement of the pressure of the liquid, the pressure point should be in the pipeline, so that the pressure-conducting tube does not accumulate gas, gas measurement, the pressure point should be in the pipeline above, so that the pressure conduction tube When measuring liquid pressure, the pressure point should be at the lower part of the pipe so that no gas can be accumulated in the pressure-guide pipe.

7. What is the reason for the pointer not moving?

Possible reasons are: the valve of the calibrator is not opened; the pointer is loose and one end of the pointer touches the dial; the center hole of the sealing washer of the calibrator connector is blocked, so the working medium can not be transmitted into the gauge; the medium in the oil cup of the calibrator is too dirty, which clogs the spring tube or the transmission channel; the rubber skin at the top of the screw rod of the calibrator is damaged or the spring tube is ruptured, which leads to a large amount of oil leakage.

8. What is the reason for the pointer to fall back?

There may be oil leakage from the calibrator or the needle valve of the pressure gauge oil cup is not smooth resulting in poor sealing, or there may be cracks in the spring tube.

9. What is the reason for the needle skipping phenomenon?

The teeth of the sector gear may be corroded, worn, or stained, or the pointer shaft is tilted or bent to rub against one side of the dial.

9. What are the reasons for the needle not returning to zero?

The return error and tap displacement may be overshooting, the hair spring is not sufficiently coiled or tensioned, or the pointer is loose.
