1.0 OVERVIEW
The Smart Laser Sensor (SLS) is a self-contained unit intended to be used to
make non-contact speed measurements from rotating targets at distances
up to 65 feet (19.8 m) or to provide non-contact reference points to balancing
equipment. Refer to Section 6.0 for an overview of operation. The unit will
output one (TTL Compatible) pulse per revolution and has the ability to
compute the RPM internally and output the ASCII values to any equipment
capable of receiving an RS232 input. For best performance use reflective
tape for the target.
2.0 INDICATORS AND SWITCHES
1.
On Target
LED
Lit whenever the sensor is receiving a
reflected signal back from the target. As the
frequency increases, it will be on solid unless
the measured frequency is not stable. This is
useful in setting up the unit.
