Amplified Variable Reluctance Sensors
Digital Magnetic/VRS Pickups
These active sensors include a built-in amplifier in a Variable Reluctance Sensor. A digital output (square wave signal) is produced at the same rate as targets passing by. They are used in a wide range of applications for speed sensing of ferrous targets. Flowmeter turbine blades, power transmission and timing gears, engine flywheels, bolt heads, and shaft keyways are typical targets.
Low drag versions are available for use with flow metering of low viscosity fluids and gases. Intrinsically Safe and Explosion/Flame Proof versions are also available for Hazardous Locations. In many other cases, this sensor type can be replaced by a Hall Effect Zero Speed Sensor.
