Stainless steel pressure gauges are mainly used for pressure testing in industrial sectors such as metallurgy, power, petroleum, chemical, light industry, and machinery. Stainless steel pressure gauges rely on measures such as internal filling with damping oil and supporting buffering devices. Has good shock resistance performance. Suitable for situations where the pressure of the tested medium undergoes strong pulse changes or pressure shocks, and where it is often suddenly unloaded during production processes, as well as places with large environmental vibrations. The instrument can measure the average pulsating pressure of gases and liquids. To overcome the damage caused by strong medium pulses and environmental vibrations to the instrument, ensuring the accuracy of readings.
To prolong the service life of stainless steel pressure gauges, it is necessary to properly calibrate the indication error, return error, and tap displacement. Let's take a look together below:
The method for verifying the indication error of stainless steel pressure gauges is carried out according to the division line marked with numbers. During the verification, the pressure is gradually and steadily increased (or decreased). When the indication reaches the upper limit of the detection, the pressure source is cut off, the pressure is withstood for 3 minutes, and then the original verification point is smoothly decreased (or increased) in reverse order for verification.
Return error refers to the allowable error values specified in Table 1 for the same point calibration during both boost (or buck) and buck (or boost) calibration.
Lightly tap the displacement, and for each point during the boost (or buck) and buck (or boost) calibration, the change in indication caused by the lightweight case shall not exceed 1/2 of the allowable error value specified in Table 1.
Indication error, for each calibration point, Aichi Mall reminds you that during the boost (or buck) and buck (or boost) calibration, the difference between the front and rear indications of the lightweight watch case and the standard instrument indication should meet the requirements.
So that's all for the above introduction on the calibration of stainless steel pressure gauges. I hope it can be helpful for your understanding.
