BXY6001- Differential Pressure Transmitter
The BXY6001 differential pressure transmitter is used to measure the liquid level, density, pressure, and flow rate of liquids, gases, or vapors, and then convert it into a 4-20mADC HART current signal output. BXY6001 can also communicate with RST375 handheld terminal or RSM100 Modem for parameter setting, process monitoring, etc.

Range limit
Within the upper and lower limits of the range, it can be adjusted arbitrarily.
It is recommended to select range codes with the lowest possible range ratio to optimize performance characteristics.
Zero point setting
The zero point and range can be adjusted to any value within the measurement range in the table, as long as the calibrated range is ≥ the minimum range
Installation position impact
The change in installation position parallel to the film surface will not cause zero drift. If the installation position changes by more than 90 ° to the film surface, there will be zero drift within the range of<0.4kPa, which can be corrected by adjusting zero. No range impact.
output
2-wire system, 4-20mADC, selectable for digital communication with HART output, with options for linear or square root output.
Output signal limit: Imin=3.9mA, Imax=20.mA
Alarm current
Low alarm mode (minimum): 3.7 mA
High alarm mode (maximum): 21 mA
No alarm mode (hold): maintain the effective current value before the fault
Alarm current standard setting: high alarm mode
response time
The damping constant of the amplifier component is 0.1s; The sensor time constant is between 0.1 and 1.6 seconds, depending on the range and range ratio. The additional adjustable time constant is 0.1~60s.
The impact on nonlinear output (such as square root function) depends on that function and can be calculated based on it.
Preheating time:<15s
ambient temperature
-40-85 ℃
When equipped with LCD display and fluororubber sealing ring, -20~65 ℃
Storage temperature/transportation temperature
-50-85 ℃; With LCD display: -40~85 ℃
working pressure
The rated working pressure is divided into three levels: 16MPa, 25MPa, and 40MPa
Static pressure limit
From an absolute pressure of 3.5kPa to the rated pressure, the protective pressure can be greater than 1.5 times the rated pressure and applied to both sides of the transmitter.
Unidirectional overload limit: Unidirectional overload can reach rated pressure
