Product Description

The  EJA440E  high-performance pressure transmitter adopts monocrystalline silicon resonant sensing technology, which 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 output, and has functions such as fast response, remote setting, and self diagnosis.

Core Advantage

1. Ultra-high Accuracy: Reference accuracy up to ±0.055% span, delivering stable and reliable measurement under high      pressure.

2. Ultimate Stability: Long-term stability of ±0.1% URL over 10 years, greatly extending the calibration cycle and      reducing maintenance costs.

3. Fast Response: Standard response time of 90 ms, suitable for dynamic high-pressure process control.

4. Safety Certification: Standard SIL 2 (Exida/TUV) safety level, supports redundant SIL 3 applications, compliant      with ATEX/IECEx/FM explosion-proof standards Yokogawa Electric Corporation.

5. Digital Sensing: Directly outputs digital signals without analog-to-digital conversion errors, featuring strong      anti-interference capability and excellent repeatability. Yokogawa Electric Corporation.
