1. Electric contact pressure gauge is actually gauge control circuit switch, is only one more on normal pressure gauge electric contact signal device, as a result, the pressure of calibration and verification of ordinary pressure gauge is the same, only a partial certified pressure, still need to increase the verification for the electric contact signal device.

2. Steps for verification of contact pressure gauges

Install the pressure gauge on the calibrator and set the two signal contact Pointers outside the upper limit and lower limit respectively with the needle extractor. Certified value, the upper and lower limits of the signal contact pointer is scheduled for more than three different check point, slowly increase or reduce the pressure, until the signal instantaneous, the standard pressure gauge readings and signal pointer value, the deviation between the absolute value of basic error must not exceed the allowed.
