The RHL4 Series is KA Sensors’ latest model for monitoring ride height on the fly. It uses laser triangulation sensors to give an accurate measurement of the ride height, even under race conditions.
By reflecting a laser beam off the track surface to a CCD detector, the device achieves a standard measurement range of between 60.96mm and 264.16mm, a measurement rate of up to 4Khz and 0.1% linearity.
It can withstand temperatures between 0°C and 55°C (32°F and 131°F) and vibration levels of more than 20g. The anodized aluminum housing weighs 48g. The supply voltage is a common 11-30V, which is readily available on most datalogging systems and the analog voltage output is 1-5V. Onboard compensation ensures that different track colors and surfaces are correctly measured without error.
