Spot supply of the old model Yokogawa EJA130A high static pressure differential pressure transmitter
The Yokogawa EJA130A high static pressure differential pressure transmitter is a high static pressure differential pressure transmitter under the A series of the Chongqing Chuan Instrument Yokogawa EJA transmitters. It uses a digital sensor - a single crystal silicon resonant sensor, which outputs a pair of differential digital signals, directly eliminating external interference in the sensor part, creating a new era for transmitters. It is used to measure the level, density, and pressure of liquids, gases, and steam, and then converts these measurements into a 4-20mA current signal output.

Detailed introduction
1. Product Overview:The Yokogawa EJA130A high static pressure differential pressure transmitter is a high static pressure differential pressure transmitter under the A series of the Chongqing Chuan Instrument Yokogawa EJA transmitters. It uses a digital sensor - a single crystal silicon resonant sensor, which outputs a pair of differential digital signals, directly eliminating external interference in the sensor part, creating a new era for transmitters. It is used to measure the level, density, and pressure of liquids, gases, and steam, and then converts them into a 4-20mA current signal output. The Yokogawa EJA130A can also communicate with the BRAIN handheld device or CENTUM CS/μXL or Rosemount HART475 handheld device for settings and monitoring. The product has higher accuracy (±0.075%), higher stability, and reliability, and has received widespread acclaim since its market launch.
Here are the key features of the Yokogawa EJA130A High Static Pressure Differential Pressure Transmitter:
High Static Pressure Capability: Handles up to 4,500 psi working pressure, with a burst pressure of 10,000 psi—ideal for demanding process environments.
Superior Accuracy: Delivers ±0.065% of span accuracy, ensuring reliable measurements even under extreme conditions.
Long-Term Stability: Maintains ±0.1% of URL over a 5-year period, minimizing calibration needs.
Digital DPharp Sensor: Uses Yokogawa’s patented digital resonant sensor technology for precise, real-time diagnostics and error detection.
Communication Flexibility: Supports BRAIN, HART, FOUNDATION™ Fieldbus, and PROFIBUS PA, offering seamless integration with various control systems.
Wide Rangeability: With a 100:1 turndown ratio, it adapts well to fluctuating process conditions.
Compact and Rugged Design: Engineered for reliable operation in tight spaces and harsh industrial environments.
Self-Diagnostics: Built-in capabilities for continuous performance monitoring and early detection of potential failures.
