Low Flow Transmitter Eja115 - China

The EJA Series is available with BRAIN, HART, FOUNDATION™ fieldbus or

PROFIBUS PA communication protocols.

The model EJA115 Low Flow Transmitter is a differential pressure transmitter assembled with an integral orifice and excellent for very low flow measurement.

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 with the differential pressure measurement span variation of the differential pressure transmitter enables a wide range of very small flow measurement.

Features

Excellent performance and stability

The EJA series uses a silicon resonant sensor 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 Yokogawa 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.
