Product Description

The  EJX210A  flange mounted differential pressure transmitter adopts single crystal silicon resonant sensor technology, which is  suitable for measuring the liquid level and density of liquids that are prone to crystallization or precipitation.  EJX210A  converts the measured differential pressure into a 4-20mA DC current signal output, which can measure, display, or  remotely monitor static pressure. It has functions such as fast response, remote setting, and self diagnosis.

Key Features

1. High-precision Measurement: Differential Pressure Accuracy ±0.075% URL, Static Pressure Accuracy ±0.2%.

2. Long-term Stability: ±0.1% URL per year, reducing calibration frequency and lowering maintenance costs.

3. Fast Response: Response time of 120 ms, suitable for dynamic liquid level and pressure monitoring.

4. Functional Safety Certification: Certified by Exida & TÜV SIL 2/3 and compliant with IEC 61508.

5. Multi-communication Support: Standard with HART 5/7, optional BRAIN, FF and PROFIBUS PA, compatible with      mainstream DCS/PLC systems.

6. Intelligent Diagnosis: Multi-sensing technology can detect faults such as impulse line blockage and abnormal heat      tracing to provide early warning.

7. Local Operation: Equipped with backlit LCD, supports Local Parameter Setting (LPS), and configuration can be      realized without a handheld communicator.

8. Flange Isolation: Direct flange mounting design with isolating diaphragm to prevent clogging, suitable for      viscous/crystallizing media.

Working Principle

EJX210A adopts a monocrystalline silicon resonant sensor, which can simultaneously measure differential pressure,  static pressure, and temperature. It dynamically compensates for temperature drift andstatic

pressure effects through digital signal processing, directly outputting high-precision digital signals without  analog-to-digital conversion errors, ensuring stable and reliable performance under all operating conditions.
