EJA440E High-Performance Pressure Transmitter
The EJA440E High-Performance Pressure Transmitter adopts single-crystal silicon resonant sensing technology and is suitable for measuring the pressure of liquids, gases, or vapors. The EJA440E converts the measured differential pressure into a 4–20mA DC current signal for output, and features functions such as fast response, remote setting, and self-diagnosis.
Functional Characteristics of the EJA440E:
- Accuracy: ±0.055%
- Stability: ±0.1% URL per 10 years
(Note: “URL” stands for “Upper Range Limit”, a professional term in the instrumentation field, referring to the maximum value within the transmitter’s measurement range.)
- Response time: 90 milliseconds
- Certifications: TUV and Exida SIL 2 / SIL 3
(Note: “SIL” is short for “Safety Integrity Level”, a standard for evaluating the safety performance of industrial control systems, with SIL 3 representing a higher safety level than SIL 2.)
- Local Parameter Setting (LPS)
- Supported communication protocols: HART 5/7, HART (1~5V DC) low-power type, FF Fieldbus, PROFIBUS PA, and BRAIN.
