1. Performance specifications
Zero benchmark calibration range, under reference conditions, filled with silicone oil and 316L stainless steel isolation diaphragm. )
1.1. Reference accuracy
± 0.1% calibration range

1.2. Stability:
6 months, ± 0.1% URL
1.3. Environmental temperature impact
Zero point error: ± 0.2% URL/56 ℃
Overall error: ± (0.2% URL+0.18% calibration range)/56 ℃
1.4. Vibration impact:
In any axial direction, the vibration effect at 200Hz is ± 0.05% URL/g
1.5. Power supply impact:
Less than ± 0.005% output range/volt.
1.6. Load impact:
There is no load impact unless there is a change in the power supply voltage.
1.7. Electromagnetic interference/radio frequency interference (EMI/RFI impact)
When the field strength reaches 30V/M from 20 to 1000MHz, the output drift is less than ± 0.1% of the range.
1.8. Installation location impact
When the liquid level diaphragm is installed vertically, the zero drift is at most ± 0.25kPa. When installing the liquid level membrane horizontally, the zero drift is at most 1.25 kPa plus the extension length of the protruding part. All zero drift can be corrected without affecting the range.
