A new version of the successful M5 Series laser optical triangulation sensor is specifically designed to monitor active body height on moving road or rail vehicles.
Sensors UK has developed a new version of its successful M5 Series laser optical triangulation sensor, specifically designed for use on moving road or rail vehicles to monitor active body height above the under surface, without making contact.
The sensor is attached to the body of the vehicle and projects a fine laser beam down to the surface where it scatters.
Some of the scattered light returns to the sensor and is converged onto a position sensitive diode to produce an analogue output, which is linear and proportional to the vehicle height above the surface.
Bitumen roads surfaces present specific problems, which are eliminated by a special high-gain laser circuit.
Sunlight is an additional influence, and a special light filter fitted to the outer case, together with software, reduces errors from this source.
Measuring ranges available are 100, 200 and 400mm, with resolutions from 300um depending on measurement speed required.
All sensors can be powered from DC supplies normally available within the vehicle.
These sensors have a wide variety of applications throughout the automotive and rail industries, where they are used on product development, test drives, quality control and analysis.
