Features
Description
The
7033 laser tachometer is used in conjunction with the 7034
wireless accelerometer. The laser tachometer projects a visible laser beam
which can be directed to gear teeth, timing belts, or rotating shafts to
measure running speed. The system requires a diffused reflective strip on
the component to be measured, which allows the laser tachometer to detect
the time between strip passings, converting this into CPM.
The
laser tachometer is assigned to a workgroup of wireless accelerometers. The
laser tachometer measures the running frequency whenever a wireless
accelerometer within its work group transmits vibration data combining it
with the vibration data at the network access point.
The 7033 is an
extremely reliable wireless device. Handshaking, packet framing, collision
avoidance, packet encoding, and error checking are all performed
automatically. For maximum confidence, the 7033 performs periodic
self-test diagnosis of power fluctuations, low battery, or harmful internal
temperatures. Should operating parameters be exceeded, the unit will either
alert the operator wirelessly or self-initiate a system reset.
