Core Technology: DPharp Digital Sensor
The DPharp sensor's ability to measure differential pressure (DP), static pressure (SP), and sensor temperature from a single sensor is a significant advantage. By providing these three crucial pieces of process data, the transmitter can perform real - time dynamic compensation for the DP measurement. It adjusts for temperature and static pressure effects, leading to highly accurate and reliable measurement results. In contrast to analog sensors, which may be damaged during overpressure events and require recalibration or replacement, the EJA110A's DPharp sensor can withstand large overpressure situations. Once the pressure returns to normal operating levels, the transmitter resumes operation within its defined accuracy and stability specifications without the need for recalibration.
Communication Capabilities
The EJA110A supports multiple communication protocols, including BRAIN, HART, Foundation Fieldbus, and PROFIBUS PA. This wide range of protocol support makes it highly compatible with different industrial control systems. In modern industrial setups, where integration of various devices is key, the EJA110A can seamlessly communicate with other components in the control network. For instance, it can transmit real - time pressure data to a distributed control system (DCS) or a programmable logic controller (PLC) for further processing and control. The digital communication capabilities also enable remote configuration, calibration, and diagnostic functions, enhancing the ease of use and maintenance of the transmitter.
Rugged Construction
The transmitter is ruggedly constructed to withstand harsh industrial environments. It has a four - bolt pressure - retaining design, an active DPharp sensor, coated 316L stainless - steel flange gasket, and a dual - seal certified to ANSI/ISA 12.27.01. These design features contribute to its long - term durability, protecting it from mechanical stress, corrosion, and leakage. In outdoor applications or in plants with corrosive atmospheres, the EJA110A's rugged construction ensures its reliable operation over an extended service life.
In conclusion, the Yokogawa EJA110A Differential Pressure Transmitter is a highly versatile and reliable instrument. Its advanced technology, excellent performance features, wide range of communication capabilities, and rugged design make it an ideal choice for various industrial applications, helping plants enhance operations, increase reliability, and simplify maintenance.

Company Profile
Main Product
Valve Positioner: A valve positioner is a crucial control device that precisely regulates the position of control valves in industrial processes. It receives control signals from a controller and compares them with the actual valve position.
Flowmeter: A flowmeter is an instrument designed to measure the flow rate of liquids, gases, or steam within a pipeline or channel.
Transmitter: A transmitter is a device that senses a physical parameter, like pressure, temperature, or level, and converts it into a standardized output signal, usually 4 - 20 mA DC or digital signals.
