Performance of general purpose oem 4 20ma flange mounted different water liquid capacitive air differential pressure transmitter:

1. Reference conditions: Zero is the lower limit and does not migrate, the temperature is 25 ° C, atmospheric pressure, 24 VDC power supply, silicone oil, isolation diaphragm 316 stainless steel, the data setting range is the same as the upper and lower limits of the range.
2. Accuracy: ±0.1% of the adjusted range is not less than 0.1URL; ±[0.05+(0.005URL/range)]% of the adjusted range is not greater than 0.1URL, not less than 0.025URL; ±[0.01+(0.006URL/range)]% of the range is not greater than 0.025URL, not less than 0.01URL.
Note: The accuracy indication already includes the effects of linearity, hysteresis, and repeatability.
3. Stability: ±0.1% URL/year
4. Temperature effect: ± (0.05% URL + 0.15% range) / 20 ° C
5. Static pressure effect: zero error: 0.1URL/6.9MPa
6. Vibration effect: It can withstand vibrations up to 200Hz in any axial direction, resulting in an error of ±0.05% URL
7. Power supply effect: less than 0.005%/V of the adjusted range
8. Load impact: no load impact
9. Installation position impact: roughly 250Pa zero point migration, can be eliminated by calibration, no range effect.
10. RF interference effects: The drift is ±0.1% of the adjusted range at a frequency of 30-1000MHz and a maximum field strength of 10V/m.
