Product details
4-20mA HART Differential Digital Hydraulic Pressure Air Sensor



Product feature of the pressure transmitter  

1 Adoption of microprocessor enhances its flexibility and function;

2 Have strong self-diagnostic capability;

3 Without mutual effect between zero adjustment and range adjustment;

4 Complete function of remote & local setting and calibration;

5 Two-wire systems, conforming to HART protocol and be capable of uninterrupted output with HART protocol terminal communication;

6 To compensate for temperature and static pressure by adopting digitized compensation technology;

7 Good stability, high accuracy, adjustable damping and good single-track overload ability;

8 Without mechanical drive parts, little maintenance work, strong resistance to vibration;

9 All general parts satisfy to the convenience of maintenance.

Pressure technical performance of the pressure transmitter

Using: liquid, gas or steam

Output signal: 4~20mA DC Output, overlay HART protocol digital signal (two-wire system)

Power supply: external power supply 24V DC, power supply range 12V~45V

Temperature range:

                Electric circuit board work at -40~85℃; 

                Sensing element work at -40~104℃
