Precision automatic pressure verification system

  Gjml700 automatic pressure verification system can replace the manual piston pressure gauge verification
The operation is convenient and simple
There is no need for manual operation in the verification process
Even those without working experience are qualified to calibrate pressure instruments
The verification work is scientific and standardized, with automatic data recording, automatic error analysis and automatic generation of verification report, so as to improve work efficiency, Realize scientific verification management
If this system is adopted, some other manual calibration tables do not need to be configured or can not be configured
The built-in Hart function can replace the Hart manual operator, set or calibrate the range of the Hart transmitter, force the output current of the Hart transmitter to be at a fixed value (such as 20mA, 12mA, 4mA), set the linear or square function, and can Hart reset the pressure sensor of the transmitter
It is more convenient to use than the Hart manual operator * gjml700 technical features: ● working medium: air, There is no need to connect external high-pressure air source and exhaust air during verification
High pressure adopts hydraulic pressure and has its own pressure making system ● pressure module range: see the table below ● user defined verification range: any value within the range
● the diameter of the internal pipeline is relatively large, and a gas-liquid separator is set, so it is not afraid of being carried with water or oil by the calibration meter
● measurement unit: kPa MPa
● pressure display resolution: 5 bits
● accuracy grade: pressure: grade 0
02 or 0
05, and the module below 1kPa is grade 0

● voltage control accuracy: touch screen display: & plusmn; Five words
● standard inspection * *: 0%, 25%, 50%, 75% and * * of the range, automatic return
The connection computer can be set arbitrarily
● custom check * *: 20 seconds, arbitrary
● check * * automatic voltage stabilization time: (10 ~ 240) seconds, adjustable
● whole process time of transmitter automatic verification (9:00 voltage stabilization): about 5 minutes
● verification time of pressure switch: about 2 minutes
● with HART manual operator function
(Hart picture is as follows) technical features of gjml701: ● working medium: transformer oil or purified water is used
There is no need to connect external high-voltage air source and exhaust air during verification

The display screen is at the side end, which will not damage the touch screen due to the falling of tools such as wrench
The fully automatic verification pressure transmitter is convenient and reliable, can print and export data, has fast voltage stabilization speed and low noise
