Principle Of Operation - SKF TKBA 10 Instrucciones De Uso

2. Principle of operation

The TKBA 10 and TKBA 20 consist of two units that attach magnetically
to the side of each pulley. The transmitter unit emits a laser line that is
projected onto the relector unit. The relector unit has a target area with a
central reference line. The laser line is then relected to the transmitter unit
for a reading on the second target area, greatly increasing the accuracy.
Depending on the position and orientation of the laser line projected on the
target areas, it is possible to determine the type of misalignment and
how to correct it. Belt alignment is easily performed by adjusting the
moveable machine(s) until the laser lines coincide with the reference lines on
both units.
