Cement and Mineral Industries Use Laser Rangefinders to Profile Rotary/Clinker Kilns

The AR2700 High-Speed Long Range Sensor has two main advantages over other laser rangefinders at long distances: first of all, its measurement speed, and secondly, accuracy at that speed.

These advantages are especially useful in situations where ambient temperature near the target is high. Such is the case with profiling rotary kilns.

The AR2700 can be mounted up to 230 ft. (70 m) away* from a rotary or a clinker kiln. With a maximum measurement frequency of 40,000 Hz, the AR2700 can give a detailed profile of the shape and runout of the kiln in real-time as it is turning. This gives cement and mineral companies the data they need to ensure the equipment is in good shape. Problems can be caught early so repairs and modifications can be made to keep production up and ensure the kiln’s safe operation.

Several cement and mineral companies are currently using our AR2500 sensor for this application. The AR2700 is our updated and improved version of the same sensor. It is smaller, faster, and a bit more rugged. The full output rate of 40 kHz can be collected with a RS232/422 serial connection or 4-20 mA analog output. Finally, the AR2700 uses an invisible, Class 1 infrared laser which is completely eye-safe so you don’t have to trade one safety concern for another.
