Description

Originally developed to meet the needs of automotive testing professionals, the Dynamic Measurement System (DMS) was designed for monitoring the drive and handling characteristics of vehicles. The DMS may be used in almost any application where triaxial angular rate and acceleration data is required. This inertial sensor provides both angular rate and acceleration outputs in analog and digital formats. The DMS features six accelerometer outputs. The X, Y, and Z axis outputs represent the accelerations in the plane of the vehicle body, while the second set of three outputs measure the acceleration aligned with an earth-level coordinate system. This allows forward and lateral acceleration measurements that are essentially free of gravity influences. The triaxial sensor set allows software alignment of sensors, greatly reducing any alignment errors. The serial interface is highly configurable and provides access to almost all operational parameters.

The DMS-EGP02 is designed for vehicle applications where accurate heading is required, but a magnetic compass is infeasible. This sensor is equipped with a dual GPS antenna system that provides heading data even when the vehicle is not is motion. The addition of the GPS antennas also gives vehicle velocity data to the DMS which enhances the unit’s performance during highly dynamic maneuvers such as sharp turns. This makes the DMS-EGP02 inertial gyro sensor a more complete system since it does not require velocity information to be supplied from an external sensor.

The DMS-EGP02 is useful in automotive testing, vehicle dynamics, and marine applications. This sensor can be used as a replacement for the discontinued Watson IMU-E604, and is most useful in applications where strong magnetic fields make heading data from a fluxgate magnetometer unreliable.
