SDA DC LARGE-CURRENT SENSOR SERIES SYSTEM INTRODUCTION
I Introduction
SDA DC large-current sensor is an checking and measuring device for large direct current with independent property right of intellectual and inter-checking function. We adopt technology of constant temperature on key parts to greatly bring down the effect that the temperature on the performance, and technology of hall effect to directly measure the checked current with fast response and fine linearity, as well as structure of unique magnetic circuit to prevent quality change for overload. It has been demonstrated by national department of technological authority and users’ feed-backs that its main performance index is leading the demotic industry.
The output signal from product series of SDA DC large-current sensor could directly match the second meter and feedback control circuit, with characteristic of high precision, dependable performance, small power expenditure, fast response, pleasant and reasonable structure, convenience of installation and maintenance. It’s widely used in constant checking, measuring and controlling of large direct current in realm of metallurgy, chemical industry, electric transmission and drive, and so on. It’s ideal equipment for large direct current checking and measuring, and for realization of optimizing control to economize on energy.
II Basic Principles
See to Fig.1.Electric busbar P cross iron core T of sensor. When the checked current crosses P,a magnetic field B will appear in T proportionally to the checked current,and a pressure signal V will appear proportionally to magnetic field B in Hall parts of magnetic induction in T air gap. This signal will be transmitted to output amplifier A1 and A2 of second grade power after having been disposed by balanced amplifier. Finally two groups of output pressure V1 and V2 proportional to the checked direct current will be output.
Figure .1 The working principle of figure
III Working Conditions
The sensor work normally under the condition of environment temperature of -50
℃~55℃ and relative humidity less than or equal to 80%.
The installation spot should lack serious active gases, dust and other explosive and corrosive medium. If devices of antisepsis and damp proof are needed in chemical industry, please make it clear in contract.
Then sensor’s power supply is alternating current with pressure of 220V±10%
and frequency of 50HZ.
