EJA210A/EJA220A flange mounted differential pressure transmitter

The EJA210A and EJA220A high-performance flange mounted differential pressure transmitters can be used to measure the liquid level and density of crystalline or precipitated liquids.

Product Information

The EJA210A and EJA220A high-performance flange mounted differential pressure transmitters can be used to measure the liquid level and density of crystalline or precipitated liquids, and then convert them into 4-20mA DC current signals for output.

The EJA series supports BRAN, HART, and FOUNDATIONTM fieldbus or PROFIBUS PA communication protocols.

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, 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.
