PD-750W clamp block intelligent differential pressure transmitter It 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, regulators, etc. for measurement, indication and process adjustment. Widely used in various industrial automation environments, involving water conservancy and hydropower, railway transportation, intelligent buildings, production automation, aerospace, military, petrochemical, oil wells, electric power, ships, machine tools, pipelines and many other industries.
Field of application:
PD-750W clamp-type smart differential Pressure transmitters are widely used in water plants, oil refineries, sewage treatment plants, construction, light industry, machinery and other industrial fields to achieve multi-parameter measurement of liquids, gases, and steam.
■ Fully sealed, fully isolated single crystal silicon pressure sensor with high accuracy .
■ The 24-bit CPU achieves high precision and fast response, and the display module can 360° rotation, friendly key parameter operation function
■ Powerful personal protection, the safety guard of the transmitter, even if After lightning and thunder, it still maintains stable operation.
