Profiling rotary kilns for shape and runout

Rotary kilns require preventative maintenanceThe AR4000 laser rangefinder has unique benefits to certain applicaitons that can not be met with other products. Some engineers specify high speed sampling and high accuracy. For these requirements, Acuity offers the AR4000-LIR laser rangefinder.

The AR4000 measures to 54 feet (16.5 meters) with 0.1" (2.5 mm) accuracy to speeds of 770 Hz with RS232 output. Using an optional interface card, the distance measuring device can output 200,000 Hz.

Several global equipment providers to the cement and minerals industries demands the AR4000 for a very special application. They affix the AccuRange distance laser meters to a tripod and aim it at a rotary kiln. clinker kiln measurement.As the large tube turns, they capture its profile to a computer. Back at the office, they re-create the shape of the kiln and diagnose runout and potential shape bulging problems.

Because of the dark colors of the exterior shell, the fast rotational speed, outdoor lighting conditions and long data transmission distances, the best solution was the Acuity AR4000 laser rangefinder with a 20 mW infrared laser diode and an optical bandpass filter.

In a similar applicaiton, engineers measure the position and vibration of steel connecting collars on clinker kilns.
