Description:
Productoverview: EJA110A intelligent differential pressure transmitterFor the measurement of gas, liquid and vapor flow, liquid level, density and pressure, and then turn it into a current signal output 4-20mADC.EJA110A can also use a BRAIN manipulator or CENTUM CS/ XL or HART375 communicator to communicate with each other, setting and monitoring through them. Two, field bus communication ability: EJA110A intelligent 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. The EJA series provides 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. Three, excellent performance and stability: EJA110A intelligent 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. Four, main features: The world's first - silicon resonant sensor 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.
