Fully portable precision pressure verification system

  Introduction: the full-automatic pressure calibration platform includes pressure generation, pressure measurement, electrical signal measurement and HART communication functions
It is suitable for verifying pressure transmitter, pressure switch (pressure controller), pressure indicator, etc
The portable full-automatic pressure calibration bench can be built with HART function instead of Hart manual operator, set or calibrate the range of Hart transmitter, force the output current of Hart transmitter to be at a fixed value (such as 20mA, 12mA, 4mA), set linear or square function, and reset the pressure sensor of the transmitter with Hart
It is more convenient to use than Hart manual operator * functional features: 1
It can automatically verify the pressure transmitter, pressure switch and pressure indicator
2
Verification of pressure transmitter: ● standard verification * *: 0%, 25%, 50%, 75% and * * of the range, automatic return
Custom check * *: any pressure value
● check * * default voltage stabilizing time: 20 seconds, which can be set arbitrarily between (10 ~ 240) seconds
● whole process time of automatic verification (9:00): about 5 minutes
● built in HART protocol, which can be used as a hart manual operator of an intelligent transmitter
3
Verification of pressure switch: it can automatically detect the action value and reset value of pressure switch, and detect the contact resistance of pressure switch
