Overview

The Yokogawa EJA120A micro differential pressure intelligent transmitter is used to measure small differential pressures and then convert them into 4-20mADC current signals for output. EJA120A can also communicate with each other through the BRAN controller, CENTUM CS/μ XL, or HART 275 controller for setting and monitoring purposes.

feature

-	Performance and stability
	The EJA series adopts monocrystalline silicon resonant sensor technology. Monocrystalline silicon does not exhibit hysteresis in response to changes in pressure or temperature, making it an ideal material. Monocrystalline silicon resonant sensors minimize the effects of overvoltage, temperature changes, and static pressure, providing long-term stability.

-	Small and lightweight design
	Due to the use of ASIC amplifier design to reduce packaging size, as well as the miniaturization of membrane box structure and flanges, the weight of this model has been reduced to half of the original model. ASIC design not only reduces the number of parts, but also improves the reliability of the amplifier.

-	Fieldbus communication capability
	Fieldbus is a bidirectional digital communication system, an innovative technology for configuring instrument control systems, and also a promising replacement product for the widely used standard 4-20mA analog communication in field instruments. The EJA series offers two fieldbus modes, FOUNDATION ™ Fieldbus low-voltage mode and PROFIBUS PA equipment are used to achieve collaborative work between Yokogawa Electric and other suppliers. In terms of software, the EJA series uses two AI function blocks to calculate differential pressure and static pressure, thereby achieving flexible instrument configuration.
