Yokogawa Comprehensively Upgrades DPharp EJA Series Pressure/Differential Pressure Transmitters to Capture No.1 Share of Global Sensor Market
The enhanced DPharp EJA series transmitter
Yokogawa Electric Corporation announces that it will release an enhanced version of the DPharp EJA series pressure/differential pressure transmitters, one of its core sensor products, on June 20.
While remaining in the same price range, the enhanced DPharp EJA series transmitters will now offer significantly improved performance and functionality, bringing great cost benefits to our customers. As standard features, they will have the same high-speed response and multi-sensing functionality available with the high-end DPharp EJX series.
Development Background
Pressure/differential pressure transmitters are typically used in the oil, petrochemical, and chemical industries to measure liquid, gas, and steam flow rates as well as liquid levels in tanks.
DPharp EJA series transmitters are compact, multipurpose sensors with a large installed base: five million units have been sold since this series was launched in 1994. The DPharp EJX, Yokogawa's high-end transmitter series, has self-diagnostics and other advanced functions that help plants to reduce workload and improve maintenance efficiency.
Yokogawa has enhanced its DPharp EJA series transmitters to give them the same high response speed and multi-sensing functionality found in the DPharp EJX series. These enhanced transmitters retain the high measurement precision that is characteristic of all DPharp series products.
Yokogawa will continue to make enhancements to its sensor and analyzer lineup with the aim of strengthening sales and capturing the No.1 share of the global sensor market.
Product Features
- Multi-sensing
The enhanced EJA series transmitters will be able to simultaneously measure differential and static pressure. A single enhanced EJA transmitter will thus be able to measure both the liquid level and the pressure in a tank. Previously, this could only be done with two EJA transmitters.
- High-speed response
The response time has been brought down to 90 ms, which equals the capability of the EJX series transmitters. Specifically, this is the time from the detection of pressure to the output of an electric signal. The faster response time will now allow the enhanced EJA series transmitters to be used in high-speed applications such as turbine steam volume control.
- Compact/lightweight design, with a larger indicator
The improved EJA series transmitters weigh 30% less and have indicators that are nearly twice the size of those on the non-enhanced version.
- Safety standard compliance/certification
The enhanced DPharp EJA series transmitters now comply with the International Electrotechnical Commission's (IEC) IEC61508 international safety standard on the functional safety of electrical/electronic devices, and are certified for use in safety integrity level (SIL) 2 applications as stipulated by the IEC.
About the FA-M3 Series-->
Takashi Nishijima, Director, Senior Vice President of the Industrial Automation Platform Business Headquarters, says, "We are proud to release the enhanced DPharp EJA series, which has features equivalent to those of our high-end series, while maintaining high performance and excellent stability. We firmly believe that this product series, which provides improved performance and functionality while remaining in the same price range, is significantly more cost effective. Our DPharp series of industrial pressure/differential pressure transmitters are revolutionary high-precision measurement devices that were the first ever to use a monocrystal silicon resonant sensor and micro-electro-mechanical systems (MEMS) technology in the pressure detector, which is the heart of a transmitter. We will continue to expand our pressure/differential pressure transmitter business based on our extensive lineup of EJA and EJX series products."
Major Target Markets
