DIFFERENTIAL PRESSURE TRANSMITTER - USER GUIDE
4. Technical Specifications
a. Measuring Range and Limit
*All models support PV reversal (high side / low side) except for the 1500 PSI
model.
b. Standard Specifications and Reference Conditions
Test standard: IEC 60770; zero based-calibration span, linear output,
silicone oil filling, 316L stainless steel isolation diaphragm.
c. Performance Specifications
The overall performance including but not limited to reference
accuracy, environmental temperature affects and other
comprehensive error.
Accuracy: ± 0.075 % URL (± 0.05 % URL optional model)
Stability: ± 0.2 % URL/5 years
d. Reference Accuracy
Standard and reference conditions, including linearity (BFSL),
hysteresis and repeatability.
Calibration temperature: 20 °C ± 5 °C (68 °F ± 9 °F)
Linear output accuracy:
TD = Turndown Ratio
when URV ≥ LRV, TD = URL / URV
when URV ≤ LRV, TD = URL / LRV
URL = Upper Range Limit
URV = Upper Range Value
LRV = Lower Range Value
TD ≤ 10:1, ± 0.075% URL
With a turndown ratio equal to or less than 10:1, the accuracy is
0.075% of URL.
10:1 < TD ≤100:1, ± 0.0075% x TD URL
With a turndown ratio greater than 10:1 but equal to or less than
100:1, the accuracy is 0.0075% times the turndown of the URL.
The square root output accuracy is 1.5 times the linear output
accuracy.
