Diff Pressure Transmitter

 

Pressure / differential pressure sensor using high-precision silicon sensor technology

Electronic modular design

The process connection is flexible and optional

Integrated calibration and temperature supplement

 

 

For monitoring ventilation ducts, filters and fans in HVAC areas as well as for level measurement in closed pressurized tanks.

 

 

The measurement element adopts the world 's leading high-precision silicon sensor technology, ± 0.075% accuracy, signal output 4-20 mA, and superposition HART. The communication protocol is suitable for the measurement of pressure, differential pressure and liquid level in large and medium-sized equipment and production process control The density of the static liquid can be measured together with the orig inal measurement unit The volume or mass of the liquid can be measured together with the orig inal measurement unit With the orig inal measurement matching to measure the flow of gas, steam and liquid.
