You may have probably heard about laser sensors if you like driving. Thissafety sensor device can measure distance and displacements without physical contact or touching the target. It only needs an electrical signal. The leading industry that highly takes advantage of laser sensors is automobile manufacturing. They use various types of sensors for quality assurance and testing applications.
HOW DO LASER SENSORS MEASURE DISTANCES?
1. D=ct/2.
The most typical way laser sensorsmeasure position is by calculating the speed of light, amount of time, and metre of the target. This formula can compute large or small distances.
2. Triangulation.
Another effective technique for measuring distance is triangulation. However, with this geometric method, laser sensorscan only compute distances between one (1) millimetre to hundred kilometres.
3. Pulse measurements.
This method is also known as flight measurement, as it measures distance by basing the time of each laser pulse. Pulse measurements for laser sensors work best for calculating short distances.
WHAT ARE THE DIFFERENT TYPES OF LASER SENSORS?
LASER DISTANCE METRE PD
The good thing with laser sensorsis their sturdy power and range while having a simple look. Most automobile industries use this laser type, as it can measure distances from 0.35 to 200 metres quickly and accurately.
ROTATING LASER
Rotating laser sensorswork best for rough road or site conditions. It is shock-absorbent and regularly comes with head-mounted bumpers.
LONG-DISTANCE MEASURING LASER
This safety sensor type is ideal for road measurements, such as bridges, railway tracks, or highways. Due to its perfectly-paralleled laser beams, it can measure long-range distances.
As technology continuously progresses each day, many companies introduce numerous devices and gadgets that can help provide people and industries convenience. One of which is the discovery of laser sensors. Other innovations for automobile industries today are an acceleration sensor, rotary encoder, and many more.
