Yokogawa Transmitter
Yokogawa Transmitter EJA115 Low Flow Transmitter
The EJA-A series is Yokogawa’s most successful pressure transmitter line. First released in 1991, it continues to offer high performance and high reliability for any application. With an installed base of over 4-1/2 million EJA-A transmitters worldwide, it has a proven track record that makes it a true industry workhorse.
The EJA115 is Differential Pressure Transmitter in the series that is optimized for low flow applications with the addition of an Integral Flow Orifice (IFO).
EJA115 features include:
- 5% Flow Span (Accuracy)
- External Zero Adjust

Yokogawa Transmitter EJA115 Low Flow Transmitter
The model EJA115 Low Flow Transmitter is a flowmeter comprised of a differential pressure transmitter. It outputs a 4 to 20 mA DC signal corresponding to the measured flow.
The orifice is available in six types with a bore ranging from 0.508 mm to 6.350 mm. The combination of the bore selection of the differential pressure transmitter enables a wide range of very small flow measurement.
The model EJA115 also features remote setup and monitoring through communications.
Features:
- Excellent performance and stability
The EJA series uses a formed from monocrystal silicon, a perfect material, which has no hysteresis in pressure or temperature changes. The sensor minimizes overpressure, temperature change, and static pressure effects, and thus offers unmatched long-term stability.
- Compact and light-weight design
Half the weight of conventional models thanks to miniaturization of the casing with the amplifier ASIC, pressure cell structure, and flange. The ASIC uses the minimum number of parts and improves the reliability of the amplifier.
- Fieldbus communication capability
Fieldbus is a digital two-way communication system. It is a revolutionary technology for configuring instrumentation control systems and a promising successor to the standard 4 to 20 mA analog communication used in most field instruments today.
EJA series offers two types of fieldbus models, FOUNDATION fieldbus Low Voltage Mode and PROFIBUS PA devices, which ensure interoperability between and other manufactures. As for software, the EJA series incorporates two AI function blocks that compute differential and static pressures to allow flexible configuration of instrumentation.
