Background
The electric contact pressure gauge is used as an indication control type pressure instrument, is suitable for being installed on equipment with automatic control of upper and lower limits of pressure, and is widely applied to industries such as petroleum, chemical engineering, metallurgy, electric power, machinery and the like. The electric contact pressure gauge is periodically verified according to verification rules of 'elastic element type general pressure gauge, pressure vacuum gauge and vacuum gauge' of JJJG 52-2013, and the verification period is half a year. On one hand, when the electric contact pressure gauge is detected, a detector needs to use a universal meter to determine the public end, the upper limit end and the lower limit end of the electric contact pressure gauge in advance by 3 wiring terminals; on the other hand, in the verification process, a checker needs to use the multimeter to judge the on-off state of the wiring line of the electric contact pressure gauge and read the instant indication value from the detected electric contact pressure gauge, so that the verification efficiency is low.
In the current practical work, when a public end of the electric contact pressure gauge is judged, a verification worker uses two positive and negative interface ends of a multimeter to respectively connect every two of the 3 wiring terminals of the electric contact pressure gauge in an initial state of the pressure gauge, finds out a lower limit end and the public end according to the communication relation, re-uses the two positive and negative interface ends of the multimeter to respectively connect every two of the 3 wiring terminals of the electric contact pressure gauge after pressurizing the electric contact pressure gauge, finds out an upper limit end and the public end according to the communication relation, and thus judges the public end, the upper limit end and the lower limit end of the electric contact pressure gauge.

In a word, the verification method shows that the corresponding relation can be judged only by repeatedly testing the terminal of the pressure gauge at least 2 times, and the verification speed is influenced. If an electric contact pressure gauge fault occurs, when an output signal is not communicated, further trouble is caused for the judgment of verification personnel, and the verification efficiency is greatly influenced.
