PERFORMANCE SPECIFICATIONS
| Reference Accuracy of Calibrated Span: | ±0.075%，±0.1% （If TD>10(TD=URL/SPAN), ±(0.005×TD)%）
(includes terminal-based linearity, hysteresis, and repeatability) The square root accuracy is 1.5 times of reference accuracy of calibrated span. |
| Ambient Temperature Effects： | -20℃~65℃：±(0.075×TD+0.025)%×Span
-40℃~-20℃ & 65℃~85℃:±(0.1×TD+0.025)%×Span Every 10℃ is ±0.04% ×Span (TD=1) |
| Static Pressure Effects： | ±(0.025%URL+0.05%Span)/10MPa |
| Over pressure Effects： | ±0.05%×Span /10MPa |
| Stability： | ±0.1%×Span /3 years |
| Power Supply Effects： | ±0.001% /10V (12~42V DC) |
| Output： | Two wire 4~20 mADC output with digital communications, linear or square root programmable.
HART FSK protocol are superimposed on the 4~20 mADC signal. Output range: 3.9 mA to 20.5 mA. |
| Failure Alarm (the mode can be selected): | Low Mode (min): 3.7 mA High Mode (max): 21 mA
No Mode (hold): Keep the effective value before the fault. Note: The standard setting of failure alarm is High Mode. |
| Response Time: | The amplifier damping constant is 0.1 sec; The sensor damping constant is 0.1~1.6 sec, it depends on the range and range compression ratio. Amplifier damping time constant is adjustable from 0.1 to 60 sec by software and added to response time. |
