Rotational speed sensor Greenline EX series

variable reluctanceair

The Greenline EX Series variable reluctance (VR) speed sensors are certified for use in explosive atmospheres. They consist of an iron core, an inductive coil, and a permanent magnet. Sensor Type : Speed Sensor Speed Sensor Features : Variable Reluctance Principle : Variable Reluctance Sensor Housing Material : Stainless Steel Target : Metal A ferrous pole wheel passing the sensor face changes the magnetic field strength, resulting in an AC voltage being induced in the coil. The frequency of the output signal is proportional to the speed of the moving target. The amplitude of the signal depends on speed, air gap, geometry of target, magnetic properties of target material, and the electrical load. VR sensors, also known as passive or electromagnetic sensors, do not require an external supply.
