SICK long-range distance sensors deliver high performance laser measurement
SICK has pushed the boundaries of long-range laser sensing in outdoor and harsh ambient conditions with the launch of the DT1000 and DL1000 distance sensors for highly accurate measurement and control duties in traffic management.
With SICK’s innovative HDDM+ (High Definition Distance Measurement) technology onboard, users can have confidence in the reliability of the sensor even under adverse conditions such as bright light, bad weather, dust, smoke or mist, which could otherwise obscure or deflect the laser pulses and lead to false signals.
The SICK DT1000 and DL1000 achieve best-in-class real-time repeatability and reliability with a measurement range spanning 0.2m to 1500m and cycling time of less than 1 millisecond.
Providing accurate and reliable measurement of distance to objects that are either static or moving in the sensor’s line of sight, they can also be set up to track the movement of an object across the sensor’s beam. They are therefore ideal for positioning vehicles in applications such as determining free capacity in truck parking rows, or for automated long-range detection tasks such as triggering road toll cameras.
Explains Darren Pratt SICK UK’s Product Manager for Distance Sensors, “Both the DT1000 and DL1000 offer sub-millimetre resolution which means highly-accurate results. SICK’s powerful HDDM+ with multi-echo technology masks out the false signals received from unwanted laser reflections caused by rain, snow, fog or dust. The sensors are also unaffected by bright sunlight.
“The versatile sensors use HDDM+ to offer comprehensive options to adapt the sensor to the individual measuring task with scalable adjustment to optimise distance and measurement cycle time. The sensors can be commissioned quickly and safely by the user using SICK’s SOPAS configuration tool with a graphical touch display and a red alignment laser.”
The class 1 eye safe SICK DT1000 and DL1000 use a 905nm infrared laser for measurement and a visible red laser which is turned on for alignment. The rugged dust-proof, waterproof IP65- or IP67-rated aluminium alloy housing has a heated glass window to prevent condensation and icing.
The SICK DT1000 is designed for distance measurement up to 460 metres on naturally light-coloured objects and even 150 metres for matt black, which enables it to be used on a wide range of surfaces and objects. The SICK DL1000 achieves a range of up to 1500 metres using a suitable reflector for long range control and identification of obstructions. The sensors have an ambient operating temperature range of -40ºC to +55ºC.
As standard all DT1000 and DL1000 sensors feature Ethernet communication, switchable RS422/SSI interface, 4-20mA and Push-pull transistor outputs. The on-board touch-sensitive graphical interface enables easy navigation through the intuitive menu enabling easy set-up of the electrical interfaces, echo selection, maximum and minimum distances and status information. The SICK SOPAS ET free-to-download PC software provides another option for parameterisation but also offers additional visualisation options, data logging and remote parameter configuration
