The weight of the EJA210A differential pressure transmitter has been reduced to half of the original…
Description:
A small, lightweight design: EJA210A 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. Two, field bus communication ability: EJA210A differential pressure transmitterThe fieldbus 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. The EJA210A series provides two kinds of fieldbus, FOUNDATION fieldbus? Low voltage mode and PROFIBUS PA equipment, software, using two AI function block calculation of differential pressure and static pressure, so as to realize flexible instrument configuration Third, excellent performance and stability: EJA210A differential pressure transmitterUsing 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. Four, main features: Silicon resonant sensor. High accuracy: + 0.075%; 5 years of continuous work without adjustment; The temperature effect is negligible; The static effects can be ignored. Effect: 100 thousand consecutive unidirectional voltage unidirectional overvoltage after the experiment affect the amount of less than 0.03%; The function of two-way communication (BRAIN/HART protocol, FF bus). Self diagnosis function perfect; A small, light weight (standard 3.9kg); The static effect is negligible: When a static pressure (pressure), resonant beam deformation two shape, size and material identical to the same, so the frequency change is consistent, so the deviation automatically cleared (figure similar formula and temperature influence). Excellent characteristics of unidirectional overvoltage: The liquid membrane and the membrane using corrugated box body processing technology of the original, so that the external pressure increases to a certain value, the film can fully contact with the body, silicone oil is transferred to the sensor pressure no longer increase with the increase of external force, so as to achieve the protective effect on sensor.
