Technical parameters:
1. Basic error: ± 0.075%, 0.25%, 0.5%.
2. End-base consistency error: ± 0.25%.
3. Repeatability error: 0.25%.
4. Return error: 0.25%.
5. Stability: within the range of measurement, the basic error is not exceeded within one year.
6 temperature influence: for DP, GP class, range code 4 ~ 8, error < ± 0.15% /10ºC, the maximum range limit; For other types and other ranges, the error is doubled.
7. Constant current performance: variation < 0.075%.
8. Insulation performance: Power supply resistance to earth >400M ω.
9. Response time: when power-on starts, the response time is less than 2 seconds.
10. Sensitivity: lower limit and range variation < 0.01%.
11. Supply voltage change: lower limit and range change < 0.02%.
12 steady state change: short interruption of power supply, change < 0.02%.
13. Over the limit: lower limit and range variation < 0.05%.
14. Static pressure error: DP class, for 14MPa, the change of the lower limit value is < ± 0.3%; HP class, for 32MPa, the change of the lower limit value is < ± 0.5%.
15. Influence of external magnetic field: in 400A/m(root mean square) magnetic field, the variation is less than 0.05%.
16. Mechanical vibration: vibration frequency: 50Hz, full amplitude: 0.2mm, vibration lasted for 2 hours, residual lower limit and range variation < 0.075%.
17. Installation position influence: when the sensor center measurement diaphragm is not vertical, may produce no more than 0.24kPa zero system error, but this error can be eliminated by adjusting the zero pressure fine tuning, has no impact on the range.
18. Structural materials: pressure chamber, joint, relief valve, isolation diaphragm and other parts contacting with the medium, please refer to the selection sample for details.
19. Pressure guide connection: the connection hole on the pressure chamber is 1/4-18NPT, and the connection hole on the pressure guide joint is 1/2-14NPT. The center distance can be changed by adjusting the connection head.
20. Electrical connection: the transmitter housing has two M20 x 1.5 or 1/2-14NPT screw holes for connecting cable conduits. The housing has a terminal and a test gasket. If connected with a communicator, it can be fixed on the test gasket.
21 volume absorption: < 0.16C square meters.
22. Weight: 3351 about 4kg; EBJA is about 3.5kg (excluding accessories).
23. Flameproof: flameproof Exd II BT 4; Intrinsically safe Exia II CT6.
