A field bus communication ability:
EJA130A high pressure differential pressure transmitterProvide 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, SD series uses two AI function block calculation of differential pressure and static pressure, so as to realize flexible instrument configuration.
Two, compact and lightweight design:
EJA130A high pressure differential 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.
Third, 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.
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);
Four, static effects are neglected:
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.
