Description

Discontinued Product

The IMU-E604 is a complete inertial gyro system. It features three angular rate gyros, three accelerometers, and a fluxgate magnetometer all in a compact, durable package. With this sensor suite, the Watson Inertial Measurement Unit has the capabilities of an AHRS and a DMS combined. It has full attitude outputs – bank, elevation, and magnetic heading – along with triaxial leveled accelerometer data. This allows the IMU-E604 to be used in a wide range of applications, almost any in which an AHRS or DMS might be used. This makes the inertial measurement unit a superb general purpose instrumentation package for research and automotive testing facilities.

The IMU-E604 inertial sensor outputs data via an RS-232 serial link. This allows users to easily view data from the unit. It also allows users to easily change operational parameters for the inertial measurement unit, such as the output data channel selection. In addition to the standard attitude outputs, the IMU is capable of providing triaxial rate, acceleration, and magnetometer data to the user. Watson Industries provides free software for magnetic heading calibration that can be used once the IMU is installed.
