The BT Series DRO

The BT-2 is a 2-axis unit
(X and Y)

The BT-3 is a 3-axis unit
(X,Y and Z).

The system includes scales with all mounting hardware, all cables and the digital display unit.

Both BT-2 and BT-3 work by counting the revolutions of a precision pinion on a rack with an optical encoder.

This allows the scales to be shortened by the end user with a hacksaw since it is just a matter of cutting the metal rack. The scale is nominally 0.75 inch in diameter over the cover and the readout head is 1.85 x 1.6 x 2.6 inches.
