Applications: SUP-P2051 is a high-precision smart transmitter with high-precision silicon pressure sensor which achieves the field device communication by microprocessor. It is with high accuracy superior stability, and It is suitable to measure liquid, gas, or steam flow as well as liquid level, density and pressure. It widely used in petroleum, chemical, electric power, metallurgy, water, brewing and other industrial fields.
Span/ Range Limits
|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：|
-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)|
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.
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.
