Virtual Flux and Frequency Meter

Virtual instrumentation has done revolutionary changes in the field of measurement and control in high power applications. In high power applications, direct measurement with traditional instrument may not be give accurate results and in some cases measurement of some quantities is not possible, due to complexities in the measurement. This paper describes designing of a virtual instrument. This device is used to measure magnetic field produce by electrical sources appliances. For designing of this instrument Hall Effect sensor is used. Complete circuit is designed by designing an amplifier and related circuitry for measuring the flux and frequency. This device is cheap, accurate and easy to operate. The device can also be interfaced with computer through Data Acquisition Devices and measure the frequency and flux with the help of virtual instrument develop in LabVIEW.
