Technical specification
(Silicone oil in the filling, 316L stainless steel diaphragm, under the condition of Range Rate 1: 1)

Accuracy:
1, Digital Signal: 0.1%
2, Analog Signal: 0.1%~0.2%
3, Micro-Range(≤1.5kPa): 0.2%

Ambient temperature influence / 28 C
Range Rate 1: 1 to 10: 1: ≤0.2%
Micro-Range(≤1.5kPa): 0.5%

Static pressure influence(differential pressure transmitter)
1, Zero error(Can eliminate under the static pressure status)
Static pressure from 0~13.7MPa: 0.2%/6.9MPa
Static pressure over 13.7MPa: 0.5%/6.9MPa
2, Range error: 0.25%/6.9MPa

Positive and negative transfer
Max positive transfer is 500% than min adjustment range.
Max negative transfer is 600% than min adjustment range.
After positive and negative transfer, the upper limit range, lower limit range didn't over the limit range.

Stability

(0.2%FS/year range rate 1: 1)

The impact of the installation location

The most influence of zero is 250Pa, Adjustable zero amendment, no range influence.

Vibration(besides micro range)

Carried out in any direction at 15 to 2000Hz of vibration is less than 0.2%FS
