Product Description
Differential Pressure Transmitter (CX-PT-3051A )

Brief introduction
  1. 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.
  2. The pressures are directly applied to the isolating diaphragm that provide isolation and resistance against process fluid corrosion.
  3. Being microprocessor based, the electronic circuit is extremely versatile and accurate.
  4. Combined with the sensor precision, it provides the high accuracy and range ability.
  5. Transmitter performance is improved by continuous monitoring of the sensor temperature and corresponding corrections.
  6. 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.
