Product Description
The EJA210A-EHSA1F5B-97DN/FF1/D1/HC/A/N4 is a flange-mounted differential pressure transmitter from Yokogawa Electric Corporation, part of the DPharp EJA series. It provides precision liquid level and density measurement using a silicon resonant sensor, delivering high stability, accuracy, and reliability in demanding process applications.
This model features an extended diaphragm seal for direct vessel flange mounting, eliminating separate impulse piping and minimizing plugging risk in viscous or slurry media. With digital communication capabilities (BRAIN/HART) and a rugged design, it is widely deployed in oil & gas, chemical, and refining industries where accurate process measurement is critical.
Technical Specifications
| Parameter | Specification |

Performance Advantages
The silicon resonant sensor maintains calibration over time, unaffected by static pressure, process temperature, or overpressure. Direct flange mounting reduces potential leak paths and prevents sediment accumulation, improving reliability and reducing maintenance compared to traditional transmitters.
Frequently Asked Questions
Q: What is the benefit of the extended diaphragm seal?
A: It positions the sensor flush with the vessel wall, preventing solids buildup—ideal for heavy sludge or pulp applications.
Q: Can this transmitter be recalibrated on-site?
A: Yes. Zero and span adjustments can be performed via external buttons or digital interface (HART/BRAIN), enabling easy field calibration.
