Our Bulletin 45CPD Long-range Measurement Laser Sensors are ideal for several long-range, non-contact measurement applications including: error proofing, inspection, distance measurement, verifying material position, stack level, thickness measurement, roll diameter, web winding/unwinding, long standoff distance (hot or limited space), level monitoring, and box width measurement.
The long range laser sensors are optoelectronic sensors designed for non-contact measurement of distance, displacement and speed. They feature a large measuring range from 0.5m to 3000m. This enables measurement of critical surfaces such as hot objects, which requires measurement to be taken from a safe distance. The Acuity AR1000 laser distance sensor can measure up to 30 meters on natural targets and up to 150 meters with a retroreflective target with an accuracy of ± 3 mm. This rugged sensor is built for tough, industrial environments and applications such as fill level measurement and material height monitoring.
Laser distance measurers work by sending pulses of laser light. The light reflects off a solid surface, and the measurer calculates the amount of time it takes for the reflection to return to the device. An internal processor calculates distance based on how long it takes the reflection to return. A laser sensor is an electric device that uses a focused light beam to detect the presence, absence, or distance of an object. The light that a laser sensor emits is a small bright dot, similar to a laser pointer. This dot is bright enough to be easily seen even in direct sunlight.
