Description

The EJX530A is an in-line gauge pressure transmitter_and is part of the EJX-A series feature single crystal silicon resonant sensor and are suitable to measure liquid, gas, or steam pressure. The EJX530A outputs a 4 to 20 mA DC signal corresponding to the measured pressure. It also features quick response, remote setup and monitoring via BRAIN or HART communications, diagnostics, and optional status output for pressure high/low alarm.

EJX-A series models in their standard configuration, with the exception of the Fieldbus and PROFIBUS types, are certified as complying with SIL 2 safety requirements.

• Accuracy: ± 0.04% of Span
• Response Time: 90 msec
• Stability: ± 0.1% of URL per 15 years

Enhanced Product Quality: The EJX530A with DPharp digital sensor offers the performance needed to run your operations at peak performance. This ensures on-spec product, reduced waste, and improved yield, helping you increase profitability.

Digital Performance:

Other pressure sensor technologies require an analog to digital conversion before the signal can be processed, introducing additional errors. In Yokogawa’s pressure transmitters, the DPharp sensor directly outputs a digital signal, eliminating the need for analog to digital conversion and improving performance.

Tighter Process Control:

Poor performing pressure transmitters can lead to you having to run at a lower than desired set point in your control loop or scrap product that doesn’t meet spec. The DPharp sensor exhibits greater linearity and repeatability with no inherent hysteresis, providing tighter process control.

Reduced TCO: The EJX530A reduces total cost of ownership by having safety as standard, extending calibration intervals, and utilizing a common communication platform for all protocols.

Safety as Standard:

As standard, all Yokogawa transmitters are certified for single transmitter use in SIL 2 safety applications and dual transmitter use in SIL 3 safety applications. The same transmitter can be used for both process control and safety applications. Managing two separate transmitter models is no longer necessary, reducing spares inventory and simplifying daily operations.

Extended Calibration Check Intervals:

Yokogawa EJX-A series pressure transmitters have the long-term stability of ±0.1% per 15 years under all operational conditions, reducing calibration frequencies. As you gain experience with these transmitters, the interval between calibration checks is extended. Long-term this can help reduce your maintenance cost by up to 34%. Spend your time where it is needed.

Standard Communication Protocol:

Yokogawa transmitters support all industry standard field device communication protocols. Interoperability and interchangeability can be ensured. Use all the same tools and work procedures as before. Yokogawa transmitters are available with analog 4 to 20mA signal with either BRAIN® digital protocol or HART® digital protocol; Low Power analog 1 to 5 VDC with HART® digital protocol; or all digital FOUNDATION® Fieldbus or PROFIBUS® PA protocol.

Increased Plant Availability: The proven DPharp technology of the EJX530A increases plant availability with its advanced diagnostics and quicker resolution of maintenance issues through multiple communication options. Verified by independent third parties around the world, our transmitter provides superior reliability and performance.
