The differential pressure (ßow) transmitter can measure high accuracy within the
measurement range of 0.1~40000kPa. Migration of positive and negative zero
point is not necessary for linearity adjustment.
(2) Excellent environmental adaptability
Smart static pressure compensation and temperature compensation protect the
transmitter from effects of temperature, static pressure and overpressure, and
minimize on-site comprehensive measurement error.
(3) Flexible range compression
◆ Micro range (0...6kPa) ratio: 3:1
◆ Medium range ratio: 10:1
◆ Maximum range ratio: 10:1
(4) Excellent operability and ease of use
◆ 5 digits with backlit LCD digital display
◆ Multiple display functions (Pa, kPa, MPa, %, psi)
◆ Built-in three-button shortcut operation in-place adjustment function
◆ Available in various anti-corrosion materials
◆ Comprehensive self-diagnosis function

Note: A standard (250 Ω) load resistor is required to communicate with the
handheld communicator.
◆ Power supply:
General purpose DC10.5~45V
Intrinsically safe explosion-proof DC10.5~26V
◆ Communication line conditions: Line length: up to 2km (0.75~1.25mm2 control
instrument cable, use twisted pair cable for more than 1km)
Load resistance: 250~600Ω
(DC 24V, including cable resistance)
Load capacitance: below 0.55mF
Load inductance: 3.3mH with power line spacing: 15cm or more
(Please avoid parallel wiring)
◆ Saturation current: upper limit 20.8mA
Lower limit 3.8mA
◆ Alarm current: upper limit 22.8mA
Lower limit 3.6mA

from the top three buttons of the outer casing or can be adjusted remotely by
using conÞguration software.
◆ Zero migration: Can migrate within the range of -20% to +20% of the
maximum range
◆ Output mode: linear output
Square root output
(May achieve remote adjustment via conÞguration software)
◆ Ambient temperature: -40~+85° C

◆ Square root output accuracy
Output Accuracy
≥50% Same as the reference accuracy
50%~Dropping point Reference accuracy x 50
Square root output (%)
◆ Power supply impact: ±0.005%/1V
◆ Installation position influence: Installation position changes in the direction
parallel to the diaphragm will not cause zero drift. If the installation position and
the diaphragm surface change by more than 90° , zero drift within the range of
0.4KPa can be corrected by zero adjustment.
◆ Response time: 90ms
◆ Damping: Time constant can be adjusted within 0~99.9 seconds
