How to detect the pressure value displayed
Test method one:
Because of the pressure switch display table receiving signal, the sensor broken on the need for digital display table different corresponding to the input signal.The ammeter and resistor connected to the circuit, now began to adjust the resistance value, ammeter display input digital display table standards on current value, and then record the standard pressure value, the corresponding standard pressure value calculation, comparing with digital display table, if the gap is bigger, is not qualified, should be readjusted
Method two:
Make pressure switch power supply disconnect and remove the shell and internal pressure sensors will disconnect terminals, USES own instrument for testing, if similar, is a new instrument just meets the requirements of his own.
The above: The definition of pressure switch
