The
industry-unique, patented Model 299
LASETACH® II is a noncontact optical speed sensor that operates reliably in
both industrial lighting and outdoor sunlight. It supplies speed and phase reference to
all ACES Systems' analyzers for on-wing trim balancing of turbine engine fans,
propellers, and rotors and can be wired directly into test cell systems. The Model 299
will detect prop or turbine speeds from 5 to 100,000 RPM. Sensitivity/gain is controlled automatically by the Model 299
LASETACH II to produce the best results for the environment it is being used in. There are
no manual adjustments to be made by the operator. When the Model 299 strikes the
target, all adjustments are automatically made and the unit is ready for use.
The Model 299 LASETACH II can be mounted directly to
the wing, fuselage, or skids up to 30 feet from the target, allowing you to obtain an
accurate RPM reading without the need to remove probes, sensors, or access panels to place
the optical speed sensor close to the target.
The Model 299 uses a semiconductor diode to produce a
high intensity laser light at a wavelength of 670 nanometers. The red light is directed
through a lens which collimates it into a narrow beam. The beam dissipates
very little over the operational distance and is concentrated on the target area where a
normal optical speed sensor cannot be. The optimal distance for a typical speed sensor is
12 to 18 inches from the target, the Model 299 functions effectively at up to 30 feet from
the target.
The laser beam is projected to a retroreflective
target on the rotating component. Each time the target passes the laser, the beam is
reflected back to the LASETACH II where it produces an electrical pulse. The pulse is then
passed to the analyzer where it is displayed as a number of pulses (revolutions) received
in one minute (RPM). |
