Hazardous Location VRS sensors are designed for use in locations

where explosion-proof or intrinsically safe sensors are required.

Passive VRS (Variable Reluctance Speed) Magnetic Speed sensors

are simple, rugged devices that do not require an external voltage

source for operation. A permanent magnet in the sensor establishes a

fixed magnetic field. The approach and passing of a ferrous metal

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. The output signal of a VRS sensor is

an ac voltage that varies in amplitude and wave frequency as the

speed of the monitored device changes, and is usually expressed in

peak to peak voltage (Vp-p). One complete waveform (cycle) occurs

as each target passes the sensor’s pole piece. If a standard gear were

used as a target, this output signal would resemble a sine wave if

viewed on an oscilloscope. Honeywell also offers VRS sensors for

general purpose, high output, power output, high resolution and high

temperature, as well as low-cost molded versions.
