Description:
Productoverview: EJA430A intelligent 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, static effects are neglected: EJA430A intelligent pressure transmitterWhen 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). Three, excellent properties of unidirectional overvoltage: EJA430A intelligent pressure transmitterThe 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. Fourth, the 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; The one-way effect overvoltage is equal to or less than 10 million + 0.03% continuous unidirectional overvoltage test; The function of two-way communication (BRAIN/HART protocol, FF bus); Self diagnosis function perfect; A small, light weight (standard 3.9kg). Five, selection table: EJA430A:
