EJA510A/530A adiabatic/pressure transmitter uses ASIC amplifier design to reduce packaging, as well …
Description:
A small, lightweight design: The EJA510A/530A absolute pressure / pressure transmitterThe 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: The EJA510A/530A absolute pressure / 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.
Three, product application: <strong style="font-family: 微软雅黑, Arial, Helvetica, sans-serif; font-size: 14px; line-height: 24px; white-space: normal; margin: 0px; padding: 0px; border: 0px; background-color: rgb(255, 255, 255);"> The EJA510A/530A absolute pressure / pressure transducer</strong> for measurement of gas, liquid and vapor flow, liquid level, density and pressure, and then transforms it into 4-20mADC current signal output.EJA510A/530A can also use a BRAIN manipulator or CENTUM CS/ XL or HART275 communicator to communicate with each other, setting and monitoring through them.
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.
