Structural Characteristics
It features cylindrical housing, rotating digital display head, threaded process connection, top cable entry and local zero/span adjustment.
Working Principle
Process pressure acts on the silicon piezoresistive sensor, causing a resistance change proportional to pressure. The microprocessor conditions the signal, applies temperature compensation, and produces a 4-20mA output with superimposed HART digital communication.
Installation Requirements
Install in process line with appropriate thread adapter. Pressure seal with appropriate sealing washer. Wire 2-wire 4-20mA loop. Configure range and damping via HART communicator. Vent gas or prime liquid after installation.
