EST4300 Smart Pressure Transmitters (Remote Seal)

EST4300 Smart Pressure Transmitters Remote Seal type is microprocessor-based measuring instrument. With advanced microprocessor technology-enabled temperature and nonlinear compensation, EST4300 Remote Seal features higher measurement accuracy, better temperature characteristic, and stability and reliability. EST4300 Smart Pressure Transmitters Remote Seal, which is compatible with HART 475 field communicator, is used to measure the level, density, and pressure of liquid, gas, and steam, convert it to 4-20mAdc current signal outputs.

EST4300 Smart Pressure Transmitters Remote Seal type is designed for reliability in even the toughest applications, and is capable to guard against hot and cold, corrosive or erosive processes. The seal system features a variety of solutions, including industry-specific seals for difficult processes and provides reliable, remote measurements.

Besides, as the capillary length can be from 3m~10m, special attention must be paid to the installation position of the capillary to ensure the pressure tested is within the measuring scope of the basic sensing element. Compatible with HART 475 field communicator.

For most cases, the measurement can performed with a DP or GP transmitter; however, for any of the following situations, a remote differential pressure transmitter shall be used.

Where the process liquids are prone to solidifying or crystallizing

Where the process liquids are too thick or contains suspended solid

Where the process liquids can easily block the impulse lines

Where the process liquids are hot or corrosive, and cannot be measured directly

Where the process liquids are food or other materials that cannot be contaminated
