Precise Distance Measurements with Dimetix Laser Sensors

D-Series Dimetix Laser Distance Sensors provide accurate and reliable measurements for a wide range of applications. With a measurement range of up to 500 meters and an accuracy of up to 1 mm, these sensors are ideal for both indoor and outdoor use.

Laser distance sensors, such as the Dimetix D-series, are highly accurate and reliable devices that can measure distances with precision and speed. These sensors use a laser beam to emit light towards an object, which then reflects back to the sensor. The time it takes for the light to travel to the object and back is used to calculate the distance between the sensor and the object.

Applications with laser distance sensors

The Dimetix D-series laser distance sensors are specifically designed for industrial and automation applications, where precise distance measurements are required in challenging environments. Dimetix laser sensors are ideal for a wide range of applications, including:

  • Construction and surveying: These sensors are used to measure distances and heights in construction and surveying applications.
  • Mining: They can be used to measure the height of rock faces and the distance between mining equipment.
  • Robotics: They are used in robotics for position and distance measurements.
  • Logistics: They can be used for position detection in logistics and warehouse applications.

How Do Laser Distance Sensors Work?

Laser distance sensors work by emitting a laser beam that reflects off a target and returns to the sensor. The time it takes for the laser beam to return is used to calculate the distance between the sensor and the target. The sensor emits the laser beam in a pulsed manner, allowing it to measure distances quickly and accurately.

Dimetix laser sensors use time-of-flight (TOF) technology to measure distances. They emit a laser beam in the near-infrared range, which is invisible to the human eye. The laser beam is modulated in a sinusoidal pattern, allowing the sensor to differentiate between the emitted signal and any ambient light. The reflected signal is then detected by the sensor and the distance is calculated using the TOF principle.

How to Choose the Right Laser Sensor for Your Application

When choosing a laser sensor, it's important to consider the specific needs of your application. Some of the key factors to consider include:

  • Measurement range: Choose a sensor with a measurement range that covers the distances you need to measure.
  • Accuracy: Make sure the sensor provides the level of accuracy you need for your application.
  • Environmental conditions: Consider the temperature, humidity, and other environmental factors that may affect the sensor's performance.
  • Output options: Choose a sensor that provides the output format you need, whether it's analog, digital, or something else.

Extended applications for laser distance sensors

Measuring the position of lock gates
Dimetix laser distance sensors are being used to monitor lock gates. This ensures that the amount of water discharged is known at any given time. The sensors measure the exact position of the sluice gate down to the last millimetre and are completely non-contact.

Cutting application
Length-splitting devices are often used in the metal industry. However, many standard solutions currently available on the market are not ideal for some companies. Dimetix laser distance sensors offer an affordable specialised model.

Pressurised tunnel monitoring
An automated monitoring system is used inside a pressurised tunnel to measure the penstock's passive bias during the injections. If the limit values are exceeded, a warning light comes on, so the injections can be stopped.

Monitoring railway infrastructure
Precise distance measurement is vital when rail infrastructure is being built, whether for new construction or maintenance. High-speed trains of the latest generation travel at maximum velocities of more than 300 km/h. In order to maintain the rolling stock at such speeds, millimetre-precise measurement is essential. 

Monitoring of rock formations above railway tracks
Dimetix sensors are being used to monitor debris flow activity. These rocks can cause the build-up of a mountain stream, which may lead to the flooding of a railway line. Two additional lasers are used to monitor a large rock that's moving downhill and alert communities that may be in danger.

Movement of large structures
For moving large structures, such as bridges and buildings, the PolyDist system is the perfect solution. Using up to four Dimetix sensors, the movement procedure is continuously monitored so that the structure can be accurately moved and repositioned.

Truck position measurement
Due to increasing traffic and increasingly complex and time-consuming tasks, a system has been developed to speed up the customs inspection of heavy goods vehicles. This equipment can significantly reduce the time needed to check vehicles by using sensors to determine the position of trucks. Customs uses mobile X-ray equipment to check the contents of lorries and containers. During the scanning process, the movement of the scanner must be accurately determined.

Measurement of silo levels
With Dimetix laser distance sensors, you can measure the level in the silo accurately at any time. The Dimetix sensors measure on different surfaces, such as stones, sand, grains or dark surfaces.
