Description:
Productoverview: EJA210A/220A flange mounted differential pressure transmitterThe silicon resonant sensor technology.There is no lag phenomenon for silicon pressure or temperature change, is the ideal material.Silicon resonant sensor voltage, temperature change and the influence of static pressure drop as low as Zui, so as to provide long-term stability of the incomparable. Two, field bus communication ability: EJA210A/220A flange mounted differential pressure transmitterFieldbus is a two-way digital communication system, is the innovative technology configuration of the instrument control system, but also the prospect of upgrading good product updates, for the replacement of standard 4~20mA is widely used in analog communication instrument. Provide two kinds of fieldbus, FOUNDATION fieldbus? Low voltage mode and PROFIBUS PA devices, to realize the collaborative work of Henghe motor and other suppliers.The software, EJA series uses two AI function block calculation of differential pressure and static pressure, so as to realize flexible instrument configuration. Three, compact and lightweight design: EJA210A/220A flange mounted differential pressure transmitterDue to the adoption of ASIC amplifier design to make the packaging becomes small, and the miniaturization of the membrane structure and the flange of the box, this type of weight dropped to half of the original type.ASIC design not only reduces the number of parts, but also improve the reliability of the amplifier.
