Detailed introduction
1. Product Overview:The Yokogawa EJA430A pressure transmitter uses global silicon resonant sensors and microelectronic processing technology to convert pressure and differential pressure into frequency signals transmitted to the CPU, which are then converted into a 4~20mADC current signal. With its excellent performance, it is favored by a wide range of users. The Yokogawa EJA430A intelligent pressure transmitter can also communicate with the BRAIN handheld device or CENTUM CS/μXL or Rosemount HART 475 handheld device for settings and monitoring.
2. Features of the Yokogawa EJA430A Pressure Transmitter:
1. Accuracy and Stability: Generally ±0.065%, high precision: 0.075%, and continuous operation for five years without calibration;
2. Self-diagnosis: Multi-parameter monitoring;
3. Signal-to-noise ratio: MEMS technology reduces interference and transmission noise, especially when performing A/D conversion on the same chip, which further improves the signal-to-noise ratio.
4. Product Parameters:
