Though a magnetic pickup holds an important job in industrial manufacturing, its design is quite simple. It is a coil that’s wound around a permanently magnetized probe. As ferromagnetic objects like turbine rotor blades, gear teeth, shafts with keyways, or slotted discs move through the magnetic field, they cause a change in the flux density. Each object that passes generates a complete cycle of voltage, so if the objects are evenly spaced, the total rotation will equal the total number of cycles. Magnetic pickups are often used in industrial manufacturing to gauge the speed of engines or turbines.
Monitoring the speed of engines and turbines is critical in industrial manufacturing. These parts are essential to production; any malfunction in them could set companies back days or even weeks in production schedules. A magnetic pickup has the ability to detect changes in the speed of the engine or turbine that are out of the ordinary, and because this information is easily read by computers and motion control devices, it is fairly simple to develop a running log of engine speed. This is helpful when determining when the speed of the engine or turbine changed. A record of speeds also shows the average speed that the turbine or engine maintains, and a change in these trends will be easier to detect.
Magnetic pickups are inherently designed to face the strenuous demands of industrial manufacturing. They are able to withstand the harsh conditions that are present in factories, workshops, and power plants. They work well in wet, oily, and severe environments, and they typically have vibration and shock resistant construction. However, special consideration must be given to the placement of the magnetic pickups in such conditions. A large change in temperature can often affect how well the pickup works; generally a magnetic pickup needs to be placed closer to the gear in order to provide an accurate reading when there is a possibility of an unusually large change in temperature.
