Model LT 81

The Next Generation in Non-Contact Gauging  for High Speed Blade Tip Grinders

The Lasertalk LT 81 series Rotor Gauge measures the length of turbine and compressor rotor blades, lands, and seals during and after the grinding process using state-of-the-art non contact
laser technology.

An LT 81 series system consists of a servo positioned laser probe assembly, a magnetic index sensor, and a PC for the user/machine interface. The laser probe uses a triangulation technique, operating at a 50 degree angle, to determine the distance from the probe to the rotating turbine blades, compressor blades, lands, or seals. The computer uses the distance information to produce the pertinent information needed for the grinding process. These measurements are displayed, and used to drive the digital outputs for in-process control.
