Hall Effect Speed
Sensors
Provide zero speed sensing and are available in
both oriented and non-oriented models. The target can be
either ferrous, such as a gear, sprocket, etc. or
magnetic (discrete or multi-pole). Standard MSI
Hall Effect sensors have unique safeguards built
into their circuits to prevent damage from incorrect
hookup and can be obtained in models that produce the
most popular digital outputs.
Variable Reluctance (VR) Speed
Sensors Designed for all types of environments and user
specifications. Options include hermetically sealed,
cryogenic, high temperature, intrinsically safe and
explosion proof. In addition to the more common VR
sensors, MSI also offers inductive type sensors for
applications where magnets, rather than ferrous metal,
will be sensed.
Offer low speed
response, no drag, large air gaps and sensing
characteristics which enable them to sense non-ferrous
metals like aluminum or nonmagnetic stainless steel in
addition to ferrous metal. Unlike their VR counterparts,
RF sensors are not passive devices and require signal
conditioners/preamplifiers to operate. These devices
produce a digital square wave output versus the analog
sine wave of the VR sensors.
Combine high sensitivity amplifiers
and signal conditioners with either variable reluctance
or modulated carrier (RF) transducers. Unique features
include near zero velocity (2 Hz) speed sensing, large
air gap capability and several choices of pulse
output.
Similar to Hall
Effect sensors, MR sensors are highly sensitive devices
that can detect very small changes in magnetic fields
caused by a passing target (ferrous or magnetic), and
convert this into a digital output. Versions are
available for quadrature (bi-directional) or single
direction
sensing.
