This Laser Ride Height Sensor accurately measures ride height distances from 50mm to 350mm, with a 0.03mm to 0.42mm resolution and a response time <2.0ms. The output from the sensor is a single analogue channel which can be fed to a data logger.
The sensor is supplied with a 1m unterminated flying lead or an Autosport terminated variant.
Drop out suppression
If the laser is interrupted or measuring errors occur, the analogue output will stay on the last valid output value for a maximum time of 200ms. Any valid measurement will immediately update the output. If no valid measurement was made for 200ms, then the output will drop to 0V.
Teaching the sensor new distance settings
The sensor can be taught a specific distance range within the normal operating range. This allows the 0...5V output voltage to work across a smaller measurement range.
To teach the sensor: Connect +12V to the blue wire for 6 seconds.
Within 20 seconds, with the sensor at the required new minimum distance, connect 12V momentarily to the blue wire. Move the sensor to the required new maximum distance and repeat. To reset the sensor: Apply +12V to the blue wire for 20 seconds.
A unique feature of the Cosworth laser is that in the event of damage, the laser window can be replaced so the original sensor can be reused. With most other laser ride height sensors on the market this is not the case and the whole sensor needs to be replaced.
