Supplier EJA210E Flange Mounted Differential Pressure Transmitter

WWW.DISTRIBUTORALATINDUSTRI.COM | The Yokogawa EJA210E is a high-performance flange-mounted differential pressure (DP) transmitter specifically designed for liquid level measurement in tanks and vessels, particularly for liquids that may solidify, precipitate, or contain suspended materials. It uses Yokogawa’s DPharp silicon resonant sensor technology to provide stable and accurate differential-pressure measurement. The transmitter converts the measured differential pressure into a standard output signal and can also measure static pressure.

The capsule and flange specifications above are configuration-dependent. For example, Yokogawa lists the EJA210E with M and H capsules, while process connections include 1½”, 2″, 3″, and 4″ flange sizes and JIS, ANSI, JPI, or DIN flange standards.

MEASURING PRINCIPLE

The EJA210E measures the differential pressure between the high-pressure (HP) and low-pressure (LP) sides. In level applications, the differential pressure generated by the liquid column is used to determine the liquid level inside a tank or vessel.

The flange-mounted diaphragm seal provides direct contact with the process while isolating the transmitter sensing system from the process fluid. This makes the instrument particularly suitable for viscous, corrosive, solidifying, or precipitating liquids.

PROCESS CONNECTION

The EJA210E is available in several flange configurations:

  • Flush Type: 1½”, 2″, or 3″ flange
  • Extended Type: 3″ or 4″ flange
  • Flange Standards: JIS 10K/20K, ANSI 150#/300#, JPI Class 150/300, DIN PN10/16 or PN25/40

The exact flange size, rating, and extension length must be selected according to the tank nozzle and process conditions.

OUTPUT & COMMUNICATION

Depending on the model code, the EJA210E can be supplied with:

  • 4–20 mA DC + BRAIN
  • 4–20 mA DC + HART 5/HART 7
  • FOUNDATION Fieldbus
  • PROFIBUS PA
  • 1–5 V DC + HART 7 (Low Power)

The HART 5/HART 7 version is a common configuration for integration with PLC, DCS, and SCADA systems.
