EJA310E High-Performance Absolute Pressure Transmitter
The EJA310E High-Performance Absolute Pressure Transmitter adopts single-crystal silicon resonant sensing technology and is suitable for measuring the pressure of liquids, gases, or vapors. The EJA310E converts the measured 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 EJA310E:
- Accuracy: ±0.1%
- Stability: ±0.2% 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 assessing the safety performance of industrial control systems, where SIL 3 indicates a higher safety level than SIL 2.)
- Maximum operating pressure: 3,600 psi
(Note: “psi” is the abbreviation of “pound-force per square inch”, a pressure unit widely used in industrial scenarios; 1 psi is approximately equal to 6.895 kPa.)
- Local Parameter Setting (LPS)
- Supported communication protocols: HART 5/7, HART (1~5V DC) low-power type, FF Fieldbus, PROFIBUS PA, and BRAIN.
