Detailed introduction
The Yokogawa EJA210E flange-mounted differential pressure transmitter is the next model in the Chongqing Chuan Yi Yokogawa EJA transmitter-E series, a smart differential pressure transmitter designed for flange installation. It is also specifically used to measure the density of crystallized or precipitated liquids. It utilizes Yokogawa's unique single crystal silicon resonant sensor technology, making it very suitable for measuring the flow, level, density, and pressure of liquids, gases, or steam. The Yokogawa EJA210E differential pressure transmitter can convert the measured differential pressure into a 4-20mA DC current signal output, allowing for the measurement, display, or remote monitoring of static pressure, with features such as fast response, remote setting, and self-diagnosis. The Yokogawa EJA210E flange-mounted differential pressure transmitter is an upgraded model of the Yokogawa EJA210A and Yokogawa EJA220A flange-mounted differential pressure transmitters.
Here are the key features of the Yokogawa EJA210E flange-mounted differential pressure transmitter:
High Accuracy: ±0.075% of span, ensuring precise level measurements.
Excellent Stability: ±0.1% per year, reducing the need for frequent recalibration.
Fast Response Time: 120 milliseconds, ideal for dynamic process conditions.
DPharp Digital Sensor: Provides superior performance over analog sensors, with built-in diagnostics.
Dynamic Compensation: Real-time correction for temperature and static pressure effects.
SIL2/SIL3 Certified: Certified by Exida and TÜV for use in safety instrumented systems.
Signal Characterizer: Customizes the 4–20 mA output to match specific process needs.
Local Parameter Setting (LPS): Enables configuration without external tools.
Compact and Lightweight Design: Simplifies installation and reduces load on mounting structures.
Fieldbus Communication Options: Supports HART, FOUNDATION Fieldbus, and PROFIBUS protocols.
