Technical indicators
1.Technical Parameters
Accuracy: DP, GP transmitter sensor full scale reference accuracy ±0.075% ±0.1%.
Stability: do not exceed the upper limit of transmitter ±0.2% within 12 months.
Temperature influence :Total error < ±0.3 maximum range limit, every change of 10ºC; For other transmitters and other ranges, the above error value will be doubled.
Influence of static pressure:
Class DP: For 14MPa, ±0.25% maximum range limit or ±0.5% (range code 3), corrected by zeroing at pipeline pressure.
HP class: ±0.2% maximum range limit, for 32MPa, corrected by zeroing at pipeline pressure.
Vibration impact: 0.1% maximum range limit, 10 ~ 55HZ, S = 0.15mm, in any direction.
Power supply impact: less than 0.005% output range /V.
Installation position influence: when the working diaphragm is not vertical, the zero position system error may not be greater than 0.2kpa, but this error can be eliminated by adjusting the zero position, no impact on the range.
Pressure guide connection: the connecting screw hole on the pressure chamber is 1/4-18NPT, and the connecting screw hole on the leading pressure joint is 1/2-14NPT. The center distance can be changed by changing the connecting block (51, 54, 57mm).
Electrical connection: the transmitter housing has 2 M20×1.5 screw holes for connecting the cable pipe, and there are wiring ends and measuring gaskets in the housing for testing. If connected to a communicator, it must be fixed to the measuring gasket.
2.Function Parameters
Medium used: liquid, gas and steam.
Power supply: the power supply ranges from 12 to 45VDC. Generally, the working power supply is 24VDC.
Load: The maximum load resistance RL of the circuit board is: RL = (VS-12V) 0.023A, where RL: the maximum load resistance ω, and the maximum RL during communication is 600ω; VS: power supply voltage V.
Fault alarm: The self-diagnosis program detects the fault, the analog output is higher than 22mA or lower than 3.9mA alarm, alarm high and low signs can be selected through the electronic component switch.
Transmitter STATE WRITE protection: Toggle switches on electronic components to prevent changes in the transmitter configuration.
Temperature range: Electronic circuit: -40 ~ +85ºC Sensitive element (filled with silicone oil) : -40 ~ +104ºC (filled with inert oil) : - 184 ~ + 71 ºC.
Damping: The electrical damping is 0 ~ 16s, which can be adjusted by 0.1s interval. The inherent time of the sensitive element (silicone oil filling) is 0.2s, and the damping time of the range code 3 is 0.4s.
The installation
Warning: In order to ensure the safety of the operator and the plant, it is important to have trained personnel follow the model Technical data for installation.
Installation Precautions
(1) The compression pipe should be as short as possible and avoid sharp bending.
(2) The installation slope of the compression pipe should not be less than 1:12, so as not to cause precipitation.
(3) Before connecting the pressure pipe to the transmitter, it must be blown with compressed air, and it is best to rinse with the measured medium.
(4) If the medium is liquid, the compression pipe should be completely emptied.
(5) The layout of the compression pipeline should make the bubbles in the measured liquid or the sediment in the measured gas flow back into the process pipeline.
(6) There shall be no leakage during the installation of pipelines.
Electrical connections
Check whether the working voltage is consistent with that specified on the nameplate. Power box output signals share an object line. Electrical
connections are available through The NPT1/2 or M20 x 1.5 cable inlet is connected to the terminal. The wire connection terminal can connect
to a wire with a cross-sectional area less than 2.5mm.
