Concept and Application
The Sensor Calibration System is a tabletop device/ product to be used for Hall sensor IC calibration. The copper wire wound on the setup provides a controlled/adjustable magnetic field when energised with electrical power. The device requires a power source of 25 Volts with 16 Amps. A power consumption of 400Watts. The Hall sensor IC can be calibrated/ programmed to achieve a certain range of sensitivity. However to accurately calibrate/ program the IC ,an external magnetic field is required. The setup combined with a variable power supply of 25 volts 16 amps would allow the user to vary the magnetic field density from 0~140mT. This simply allows the user to calibrate the IC as per their needs.
A Hall effect sensor is a device that is used to measure the magnitude of a magnetic field. Its output voltage is directly proportional to the magnetic field strength through it. Hall effect sensors are used for proximity sensing, positioning, speed detection, and current sensing applications. In a Hall effect sensor, a thin strip of metal has a current applied along it.
