Yokogawa EJA120E Draft Range Differential Pressure Transmitter Stainless Steel Enclosure

Details:

The Yokogawa EJA120E is a high-performance micro differential pressure transmitter. It utilizes single-crystal silicon resonant sensor technology and is suitable for measuring the flow, liquid level, density, and pressure of liquids, gases, or steam. The EJA120E converts the measured differential pressure into a 4- 20mA DC signal output, featuring rapid response, remote setting, and self-diagnosis functions. It supports multiple communication protocols such as HART 5/7, HART (1~5V DC) low-power type, FF fieldbus, PROFIBUS PA, and BRAIN
