Yokogawa Eja120e

Yokogawa eja120e is an intelligent differential pressure transmitter often used in industrial process control, which is used for pressure measurement and control of flammable and toxic gases.It can compatible with various types of sensors and controllers with high reliability and accuracy. In addition,  yokogawa transmitter also equipped with an intelligent circuit that can automatically calibrate and diagnose its own functions, making it easier to realize automatic control.

The built-in display table of the EJA120E transmitter can display all measurement data and alarm codes, etc., and can also be programmed according to your needs. In addition, the indicator runs on a separate circuit, independent of, and unaffected by, the output signal.

• It can automatically compensate temperature, pressure and other influencing factors, with high stability;
• Suitable for differential pressure measurement of different media such as liquid, gas and steam;
• Can provide various output signal forms such as current, voltage, digital signal;
•  Adopt digital intelligent design, easy to operate;
• Long service life, easy maintenance and easy operation.

Yokogawa eja120e has 40 self-diagnosis functions, two of which are unique features. One is Back-Check patented technology, which confirms and detects the correctness of calculation through real-time reverse calculation. The second is that diaphragm is an active sensor, even if the input pressure does not change, the sensor will continue to output the corresponding signal. When the sensor signal is interrupted, the transmitter can detect the sensor failure for the first time. However, when the passive sensor has no signal output, it is impossible to judge whether the pressure has not changed or the sensor has failed.
