performance index

Electric air pressure source: electric pressure range: -95 ~ 1000kPa, pressure continuously adjustable.

(two) electric hydraulic source: electric pressure, medium for transformer oil, the pressure range of 0 ~ 60MPa, continuous pressure adjustable.

(three) pressure measuring unit:

1, pressure measurement: -95 ~ 1000kPa accuracy of 0.05%F.S (optional imported inspection instrument accuracy of up to 0.025)

2, current measurement: 0 ~ 25mA accuracy 0.02%F.S

3, the computer display and pressure calibrator display test data, can simultaneously display the pressure value and the current value of the transmitter.

(four) hydraulic pressure measuring unit:

Pressure measurement: 0 ~ 60MPa accuracy 0.05%F.S, the other indicators with the pressure measurement part. The accuracy of the original imported calibrator can reach 0.025

(five) pressure meter automatic reading accuracy: the conventional pressure gauge, each pressure point recognition accuracy can reach the scale line dividing the value of the 1/20, but the pressure gauge line more than 200 when the recognition accuracy is not greater than the scale division value 1/10, and the most eye reading accuracy of 1/5 value scale line.
