PD-750W single flange extended differential pressure transmitter
Standardmechanical engineering, automation controlOf multiple parametersMeasurement
PD-750W single flange extended differential pressure transmitterCombined with the new expanded monocrystalline silicon sensing element with HART protocol and temperature compensation as standard, converting pressure changes into linear standard current or voltage signals, withExtremelyHigh accuracy and repeatability, vibration resistance, wide measuring range, suitable for variousmechanical equipment and engineering projects Fluids, gasesMedium pressure, liquid level, density measurement, equipped withOn-site programming and display functions, Multiple output options, meeting different process requirements.
PD-750W single flange extended differential pressure transmitterConverts the physical pressure of gases and liquids sensed by the measuring element into standard electrical signals (e.g. 4-20 mA, HART) for indication, recording and process control by secondary instruments. Widely used in industrial automation across hydropower, rail transit, intelligent buildings, production automation, aerospace, defense, petrochemicals, oil wells, power, shipbuilding, machine tools and pipelines.
■ Fully sealed, fully isolated monocrystalline silicon pressure sensor.
■ 24-bit CPU achieves high precision and fast response, the display module can be rotated 360°, and the button parameter operation function is friendly
■ The rugged metal electrical housing withstands demanding environments.
■ Fully isolated magnetic induction structure meets explosion-proof requirements and on-site operating specifications.
■ Strong and high-quality stainless steel process flange and ultra-thick reinforced structure are powerful guarantees for high static pressure and high overload.
