Product Description

Intelligent Differential pressure transmitter


Differential Pressure Transmitter is designed to be used with dry, clean air and gases. Perfect for VAV systems, filter monitoring, HVAC fan control, building pressurization, and leak detection systems.



Real time sensor trim during operation

The pressure signal can be linear corrected

Protective circuit and fold back circuit can minimize the incident.

The configured parameters keep same after stored in E PORM

High precision and high stability

Rough and anti-vibration components and plug-in PCB

Explosive proof configuration

Sensor trim, zero trim and damp can be adjusted



Measurement range:

Pressure Range

Maximum Static pressure

0  ~(0.125~1.6 )kPa


0  ~ (1.3~8) kPa


0  ~ (6.2~40) kPa


0  ~ (31.1~250) kPa


0  ~ (0.117~1) MPa


0  ~ (0.345~2.5) MPa



Zero trim and sensor Trim: Push buttons on device to trim or using HART operators.


Output current: DC 4-20mA, HART communication protocol

Output type: Linear, Square root (remote adjust)

Damp time: 0.1 second to 32 second, can be adjusted

Ambient temperature: -40 to 85 (without LCD); -20 to 70 (with LCD)

Operating temperature: -40 to 104

Storage temperature: -40 to 85

Ambient humidity: <95%RH

Volume change: < 0.01in or 0.16cm,

Accuracy:   ± 0.1 % FS @ Range ratio 5:1:

                      ± 0.25 % FS @ range ratio 5:1

Stability:  ± 0.5%URL within 6 month

Ambient temperature effects:  -29 to 85 (Error on zero point: 0.5%URL/56℃,                   Overall error: (0.5%URL+0.2%Rd) /56)

Vibration effects: 0.2%URL/g @ 200Hz on any axis.

Power supply:  1236VDC

Installation position effects: The zero drift is less than ± 0.25kPa, all zero drift can be tare off, no effects for range.
