The high performance Gauge / Absolute pressure transmitter BP-3000 is suitable to measure liquid, gas, or steam flow as well as liquid level, density and pressure. it outputs a 4~20 ma DC signal corresponding to the measured pressure. Its highly accurate and stable sensor can also measure the static pressure which can be shown on the integral indicator or remotely monitored via HART communications. Other key features include quick response, remote set-up using communications, self-diagnostics and optional status output for pressure high/low alarm. |

Reference Accuracy of Calibrated Span:
(includes terminal-based linearity, hysteresis, and repeatability)±0.075%，±0.1%
If TD>10(TD=URL/SPAN), ±(0.005×TD)%
Ambient Temperature Effects
-20℃~65℃：±(0.075×TD+0.025)%×Span Every 10℃ is ±0.04% ×Span (TD=1)
-40℃~-20℃ & 65℃~85℃:±(0.1×TD+0.025)%×Span
Over pressure Effects
±0.05%×Span
Stability
±0.1%×Span /3 years
Power Supply Effects
±0.001% /10V (12~36V DC)
Zero Adjustment Limits
Zero can be fully elevated or suppressed, within the lower and upper range limits of the capsule.
External Zero Adjustment
External zero is continuously adjustable with 0.01% incremental resolution of span. Re-range can be done locally using the range setting switch.
Mounting Position Effects
Rotation in diaphragm plane has no effect. Tilting up to 90℃ will cause Span C zero shift up to 0.25 kPa, others up to 0.15kpa ,which can be corrected by the zero adjustment.
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.
UpTime ＜15s
