1. Product Overview:The Yokogawa EJA110A differential pressure transmitter is from Chongqing Chuan Instrument.Yokogawa EJA transmitter-A series is the next commonly used high-performance intelligent differential pressure transmitter. Since its entry into the Chinese market in 1995, it has quickly captured a large share of the market in China due to its high reliability and high precision. After many years of field experience, it has received unanimous praise and positive feedback from a wide range of users. It has now become a trusted assistant in industrial control sites.
The Yokogawa EJA110A differential pressure transmitter uses single crystal silicon resonant sensor technology. Single crystal silicon has no hysteresis effect for pressure or temperature changes, making it an ideal material. The single crystal silicon resonant sensor minimizes overpressure, temperature changes, and static pressure effects, providing unparalleled long-term stability. It is suitable for measuring the flow of liquids, gases, or steam, as well as liquid levels, densities, and pressures, and then converting them into a 4~20mA DC current signal output.
The Yokogawa EJA110A differential pressure transmitter can communicate with BRAIN handheld controllers, HART handheld controllers (375/YHC4150X, etc.), CENTUM CS, and FieldMate, allowing for monitoring and setting of the instrument. The EJA series supports BRAIN, HART, and FOUNDATION™ fieldbus or PROFIBUS PA communication protocols.

　　3. Product Features:
1. Excellent Performance and Stability
The EJA series uses single crystal silicon resonant sensor technology. Single crystal silicon has no hysteresis effect for pressure or temperature changes, making it an ideal material. The single crystal silicon resonant sensor minimizes overpressure, temperature changes, and static pressure effects, providing unparalleled long-term stability.
2. Compact and Lightweight Design
The use of ASIC amplifier design reduces the size of the package, and the miniaturization of the diaphragm structure and flange has reduced the weight of this model to half that of the original model. The ASIC design not only reduces the number of parts but also improves the reliability of the amplifier.
3. Fieldbus Communication Capability
Fieldbus is a bidirectional digital communication system, an innovative technology for configuring instrument control systems, and a promising upgrade product to replace the widely used standard 4~20mA analog communication in current field instruments.
The EJA series offers two fieldbus modes, FOUNDATION™ fieldbus low-pressure mode and PROFIBUS PA devices, to enable collaboration between Yokogawa and other suppliers. In terms of software, the EJA series uses two AI function blocks to calculate differential pressure and static pressure, allowing for flexible instrument configuration.
