Performance Features
PD-750W single flange differential pressure pressure transmitter can convert gas, liquid and other physical pressure parameters sensed by the pressure measuring element sensor into standard electrical signals (such as 4~20mA, Hart, etc.), which can be used to supply secondary instruments such as alarm device, recorder and regulator for measurement, indication and process adjustment. Widely used in a variety of industrial automatic control environment, involving water conservancy and hydropower, railway traffic, intelligent buildings, production automatic control, aerospace, military, petrochemical, oil Wells, electric power, ships, machine tools, pipelines and other industries.

■ Fully sealed, fully isolated monocrystalline silicon pressure sensor.

■ 24-bit CPU to achieve high precision and fast response, display module can rotate 360°, button parameter operation function is friendly

■ High strength metal electric protective shell to meet the harsh environment application.

■ Fully isolated magnetic induction structure, meet the requirements of the field operation specifications.

■ Strong quality stainless steel process flange, super thick reinforced structure is a strong guarantee of high static pressure, high overload
