Cosworth’s 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 of 900μs. 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 un-terminated flying lead.
Drop out suppression: If the laser is interrupted or a measuring errors occur, the analogue output will stay on the last valid output value for a maximum time of 200 ms. Any valid measurement will immediately update the output. If no valid measurement is made for 200 ms, then the output will drop to 0V.
Teaching the sensor new distance settings: Cosworth’s laser 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. Teaching the sensor a new measurement range is a simple process;
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. If the optional AS connector is fitted, the teach connection is held to ground, and it will not be possible to teach the sensor without connector modification.
