The Yokogawa EJA120E High-performance Differential Pressure Transmitter is your ideal solution for demanding industrial applications. This high-tech emitter uses single-crystal silicon resonant sensor technology to give very accurate flow, level, density, and pressure readings. This device always gives the right results in the petroleum, chemical, and power generation businesses because its 4–20 mA DC current flow and high performance.

With its new appearance and high-tech features, the EJA120E really stands out from the crowd. You get the most accurate standard precision in the business at ±0.2%, and it stays reliable over time. You can quickly see any changes in the process thanks to the quick 150-millisecond response time, which helps you keep the best level of control.
This unit's DPharp digital sensor technology is what makes it stand out. This system continuously sends frequency readings even when pressure doesn't change, unlike standard sensors. This means you find sensor problems right away instead of thinking they are changes in the process.
The strong pressure retention system with four bolts protects your investment. The 316L stainless steel structure with Teflon coating means you get a longer working life. You can trust the double closing system in tough settings because it meets the ANSI/ISA 12.27.01 standards.

Your processes need tools that can handle things that don't go as planned. The Yokogawa EJA120E High-performance Differential Pressure Transmitter provides multiple layers of protection. The DPharp sensor design automatically protects itself from the effects of overpressure. Extra mechanical safety inside the diaphragm helps to prevent valve operation mistakes and sudden increases in pressure.
The Back-Check self-diagnostic method, which is trademarked, works all the time. It checks the quality of the signal by doing calculations in the opposite direction as the signal is being received. This means you find possible problems before they get in the way of your process control.
Your business follows safety rules. This device meets the IEC 61508:2010 and IEC 61511:2004 practical safety standards. If you have a single unit, you get SIL2 approval. If you have a redundant setup, you get SIL3. This flexibility lets you meet both safety and business needs without needing any extra tools.
The transmitter's efficiency and dependability are confirmed by independent certification from TÜV Rheinland and EXIDA. You can use these passwords for your important apps.
The EJA120E adapts to various industrial needs. You can use it for:
Its versatile design works with liquids, gases, and vapors across different temperature and pressure ranges.
The easy-to-use design helps you save time and money. With remote setting options, you can still adjust settings without having to go to the field. The self-diagnostic features lower the need for upkeep and downtime that can't be planned.
The 10:1 range ratio lets you use different measurement ranges without having to change the gear. This setting of standards makes your stock of extra parts and training needs easier to manage.
