High Temperature Industrial VRS Magnetic Speed Sensors DESCRIPTION The output signal of a VRS sensor is an ac voltage that varies High Temperature VRS sensors are designed for use in in amplitude and wave frequency as the speed of the applications where the sensor is exposed to temperatures up monitored device changes, and is usually expressed in peak to to 260 ”C [450 ”F]. Sealed Front-End versions are available for peak voltage (Vp-p). applications where the sensor is exposed to fluids, lubricants or adverse environmental conditions. One complete waveform (cycle) occurs as each target passes the sensor’s pole piece. If a standard gear were used as a Passive VRS (Variable Reluctance Speed) Magnetic Speed target, this output signal would resemble a sine wave if viewed sensors are simple, rugged devices that do not require an on an oscilloscope. external voltage source for operation. Honeywell also offers VRS sensors for general purpose, high A permanent magnet in the sensor establishes a fixed output, power output, high resolution and hazardous location magnetic field. The approach and passing of a ferrous metal applications, as well as low-cost molded OEM versions. target near the sensor’s pole piece (sensing area) changes the flux of the magnetic field, dynamically changing its strength. This change in magnetic field strength induces a current into a coil winding which is attached to the output terminals.
