LC-2100 Spatial Filter Type Speed Detector

The LC-761 Sideslip Testing System measures the vehicle’s speed with respect to the ground and the sideslip angle. Since it outputs the vehicle’s straight-line speed, lateral speed, and sideslip angle, the motion aspects during operational and stability tests can be continuously monitored. The LC-1100 detector is designed for the measurement of straight-line speeds, and the LC-2100 for the measurement of lateral speeds. Minute detector mounting angle errors have appeared until now as large speed error components in the measurement of vehicle lateral speeds. With the LC-761 system, an auto correction function is provided to correct any mounting angle error in the LC-2100 and thereby ensure accurate lateral speed measurement. Moreover, since the distance pulse output from the LC-5200 can be input as a straight-line speed signal, measurement of the sideslip angle can be performed while saving the straight-line speed data to the LC-5200’s memory.

System Configuration

(* Unable to measure under the condition of mirrored road-surface such as a puddle.)

Features

Simultaneous measurement of the straight-line speed, the lateral speed, and the sideslip angle.
Optimal system for drivability and stability tests.
Unaffected by slip and tire pressure and thereby ensure accurate measurement.
Can be measured within ±10cm of up-and-down movement, centering on the 50 cm above the ground.
Can be easily mounted to a vehicle body with a sucker.
Can be mounted on either backside or side panel of a vehicle.
Various running tests provided.

Options		LC-065 Brake Test Commander When a braking test is performed, the LC-065 inputs a voltage signal (12 or 24 VDC) from the brake lamp and a non-voltage 1a contact signal from the tape switch (provided) or other source, and outputs an external start signal for the LC Series. This enables a voltage input from the vehicle’s brake lamp to be added to the non-voltage 1a contact signal. SF-061 Carrying case for the LC-1100/2100 models LC-0001A Halogen lamp for LC-1100/2100
