Product Description

The EJX130A high static pressure differential pressure transmitter adopts single crystal silicon resonant sensor  technology, which is suitable for measuring the flow rate, liquid level, density, and pressure of liquids, gases, or  vapors. The EJX130A 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. Ultra high precision: Differential pressure measurement accuracy ± 0.04% (URL), static pressure accuracy ± 0.2%.

2. Ultra long stability: 15 years of long-term stability with ± 0.1% URL, significantly reducing calibration and      maintenance costs. Yokogawa Electric Corporation.

3. Ultra high pressure tolerance: Maximum working pressure (MWP) of 4500 psi (approximately 31 MPa), suitable for      high static pressure conditions

4. Fast Response: Response time of 150 ms, suitable for dynamic flow and pressure monitoring.

5. Safety Certification: Certified by Exida & TÜV for SIL 2/3 functional safety, compliant with IEC 61508.

6. Multiple Communication Protocols: Supports HART 5/7, BRAIN, FOUNDATION Fieldbus and PROFIBUS PA, compatible with      mainstream control systems.

7. Intelligent Diagnosis: Multi-sensing technology can detect abnormalities such as impulse line blockage and heat      tracing faults for early warning.

8. Local Operation: Equipped with backlit LCD display, supports Local Parameter Setting (LPS), and allows      configuration without a handheld device.

Working Principle

EJX130A adopts a monocrystalline silicon resonant sensor to simultaneously detect differential pressure, static  pressure, and temperature. It dynamically compensates for the effects of temperature and static pressure through  digital signal processing, and directly outputs high-precision digital signals without analog-to-digital conversion  errors, ensuring stable and reliable measurement under all operating conditions.
