1、 Product Overview
EJA110AThe high-performance differential pressure transmitter is suitable for measuring the flow rate, liquid level, density, and pressure of liquids, gases, or vapors, and then converting them into4~20mA DCThe current signal output.EJASeries supportBRAINTheHARTandFOUNDATION™Fieldbus orPROFIBUS PACommunication protocol.
2、 Characteristics
☆ Performance and stability
EJAThe series adopts single crystal technologySilicon resonant sensor technologyMonocrystalline 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 adoption ofASICThe amplifier design reduces the size of the packaging, as well as the miniaturization of the membrane box structure and flange, resulting in a weight reduction of half of the original model.ASICThe 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 standards in field instruments4~20mASimulate communication.
EJAThe series offers two fieldbus modes,FOUNDATION™Fieldbus Low Voltage Mode andPROFIBUS PAEquipment to achieve collaborative work between Yokogawa Electric and other suppliers. In terms of software,EJAThe series uses twoAIFunction blocks calculate differential pressure and static pressure to achieve flexible instrument configuration.
