Core Technologies

The EJA210A's performance is anchored by the DPharp digital silicon resonant sensor. Unlike conventional analog sensors, this technology measures pressure as a frequency, which minimizes signal drift and enhances long-term stability.

The transmitter supports flexible material options for wetted parts, including Hastelloy C-276 and Tantalum, ensuring the device remains resistant to highly corrosive process fluids found in chemical or petrochemical applications.

Frequently Asked Questions

  • Q: Can this transmitter be used in hazardous locations?
    • A: Yes. The EJA210A holds multiple explosion-proof certifications, including FM, ATEX, and IECEx. Always verify that the specific unit’s nameplate matches your facility's hazardous area requirements.
  • Q: How does the "L" range differ from the "M" range?
    • A: The "L" range (Low) is calibrated for fine, low-pressure applications (1–100 kPa), while the "M" range (Medium) is intended for significantly higher pressure applications up to 14 MPa.

Field Installation Guidelines

  • Mounting: Install the transmitter flange directly to the tank nozzle. Ensure that the mounting gasket is suitable for the process fluid chemistry and the flange pressure rating.
  • Calibration: Verify the zero point once the transmitter is installed. When measuring liquid levels, account for the hydrostatic head pressure caused by the liquid density and the specific installation height.
  • Wiring & Grounding: Use high-quality shielded, twisted-pair cabling for the 4–20 mA loop. To maintain the IP67 protection rating, ensure cable glands are tightened properly and the terminal housing cover is sealed. Ground the transmitter using the designated external screw to prevent interference.
