Digital Differential Pressure Transmitter
Brief Introduction
- Widely used for measuring differential pressure (or pressure), level, density of liquid, gas or steam and convert the value of above into current signal output or digital protocol output.
- The pressures are directly applied to the isolating diaphragm that provide isolation and resistance against process fluid corrosion.
- Being microprocessor based, the electronic circuit is extremely versatile and accurate.
- Combined with the sensor precision, it provides the high accuracy and range ability.
- Transmitter performance is improved by continuous monitoring of the sensor temperature and corresponding corrections.
- A local display permits easy reading and writing of data.
Wiring Diagrams
Connect the bench equipment as shown in Figure, and turn on the HART-based communicator by pressing the ON/OFF key. The communicator will search for a HART-compatible device and will indicate when the connection is made. If the communicator fails to connect, it will indicate that no device was found.
