Mainly used to calibrate other dead weight tester, the configuration of the piston main piston displacement system and digital pressure indication and temperature indication system provide convenient for calibration .It has the pressure port to test pressure gauges and pressure transmitters also.
Features Dual Piston pressure balance deadweight tester
1 Piston in the starting range measurement duration, the indicators in full compliance with JJG59-2007 "deadweight", JJG99-2006 "weights" national verification procedures.
2 Piston and cylinder grinding by Seiko, the roundness error and the gap is extremely small, and thus greatly improve piston rotation duration, there is a corresponding decrease in the rate of decline of the piston, increased discrimination.
3There's shut-off valve for the target gauge, can beshut off the pressure between the subject system.
4 Weight has been corrected pressure deformation coefficient and the local acceleration of gravity.
5 Optional digital display: digital temperature, displacement, pressure and other parameters of the display;
6 Measuring range: Nominal Nominal measurement range consistent with the actual measurement range.
7 Piston system can easily take out to calibrate(not to carry heavy main frame).
8The weights unit could be Kg and MPa.
9 Advanced pressurization system, lightweight and durable. Can be easily suppressed to 100MPa.
10 Using weights hanging basket structure, low center of gravity, excellent stability.
11 With fast pressure connections, no leakage.
12 Each were issued northwest measurement test center test certificate
