Model 90413 monitors steering wheel's angle

A Sensor Developments product story
Edited by the Engineeringtalk editorial team Sep 3, 2009

Sensor Developments has designed the Model 90413 Angle Measurement sensor, which tells the manufacturer the angular position of the steering wheel when the vehicle is driven straight on a test track.

The heart of the device is a two-axis MEMS inclinometer used to compensate for steering tilt.

The tilt compensation is performed by an internal microcontroller.

Powered by a 9V battery, the portable sensor mounts to the steering wheel by compressing a spring mechanism, making installation and removal fast and easy.

Since the sensor was designed for production vehicles, it does not damage the steering wheel.

The user may define any length of test between one and 30 seconds.

To operate the sensor, the user holds the steering wheel at the 12:00 position and presses the 'zero' button.

The user drives on the test track so that the vehicle is proceeding in a steady, straight line.

Pressing the 'test' button begins the test.

The sensor measures the angle for a user-specified number of seconds, then displays the average angle on the easy-to-read LCD.
