Hall Effect Sensor Work. Hall voltage is discovered by Edwin Hall in 1879. You can detect and measure all kinds of things with the Hall-effect using what's known as a Hall-effect sensor or probe. Hall-effect devices are used as proximity sensors and for positioning, speed, and current detection. When mechanical stress or forces are applied to some materials along certain planes, they produce electric voltage. Hi. 3 phase voltage transducer is mainly used for power monitoring, power control and dispatching systems in petroleum, coal, metallurgy, railway and other industries. A piezoelectric transducer (also known as a piezoelectric sensor) is a device that uses the piezoelectric effect to measure changes in acceleration, pressure, strain, temperature or force by converting this energy into an electrical charge.. A transducer can be anything that converts one form of energy to another. This will in turn affect the charge carrier’s mobility and sensitivity of Hall Effect Sensors. Hall effect devicesHall effect devices can be used to:• Measure the velocity of charged particles in a magnetic field (flow meter)• Measure the proximity of magnetic materials (Linear displacement)• Detect pulses of magnetism e.g. The MSA1000 is used for the measurement of AC and DC currents with high galvanic isolation between the current carrying conductor and output of the sensor. Hall Effect is used to measure a.c. power and the strength of magnetic field. Hall Effect is used in an instrument called Hall Effect multiplier which gives the output proportional to the product of two input signals.
