Standardmechanical engineering, automation controlDifferential pressure valueMeasurement


PD-750W clampless differential pressure transmitterCombined with the new expanded monocrystalline silicon sensing elementIt comes standard with HART protocol and temperature compensation technology, converting changes in differential pressure values into linear standard current signals, withExtremelyHigh accuracy and repeatability, vibration resistance, wide measuring range, suitable for variousmechanical equipment and engineering projects Fluids, gasesMedia differential pressure measurement, equipped withOn-site programming and display functions, Multiple output options, meeting different process requirements.





Features

FEATURES

PD-750W clampless intelligent differential pressure transmitterIt can convert physical differential pressure parameters such as gas and liquid sensed by the load cell sensor into standard electrical signals (such as 4~20mA, Hart, etc.) to supply secondary instruments such as indicating alarms, recorders, and regulators for measurement, indication, and process adjustment. It is widely used in various industrial automatic control environments, involving water conservancy and hydropower, railway transportation, intelligent buildings, production automation, aerospace, military industry, petrochemical, oil wells, electric power, ships, machine tools, pipelines and many other industries.


■ Fully sealed, fully isolated single crystal silicon pressure sensor with high accuracy.

■ 24-bit CPU achieves high precision and fast response, the display module can be rotated 360°, and the button parameter operation function is friendly

■ Powerful personal protection, the transmitter's safety guard, still maintains stable operation even after lightning and thunder.

■ The rugged metal electrical housing withstands demanding environments.

■ There are no mechanical moving parts and little maintenance.

■ Fully isolated magnetic induction structure meets explosion-proof requirements and on-site safe operation specifications.

■ Strong and high-quality stainless steel process flange and ultra-thick reinforced structure are powerful guarantees for high static pressure and high overload.
