CXM543 (High Speed Digital Orientation Sensor)

High Speed Digital Orientation Sensor, CXM543

High Resolution Fluxgate Magnetometers
MEMS Accelerometers
± 1.5° Accuracy in Azimuth (Heading)
± 0.5° Accuracy in Inclination and Roll
Accurately Senses Through All Orientations
Computes Heading, Roll, & Pitch
Applications

Magnetic Compassing for Land or Marine Use
Vehicle Orientation
Remotely Operated Vehicles
Magnetic and Gravity Field Measurements
 
The CXM543 is design to measure the 3-axis orientation of a platform or vehicle to which it is attached. The CXM543 determines inclination and roll angles using a 3-axis accelerometer to measure the direction of earth's gravity. The azimuth angle is determined by measuring the earth's magnetic field using a 3-axis magnetometer subsystem. An internal hard iron calibration program is provided to reduced the effects of magnetic distortion from the mounting environment.

CXM544 (Micro Orientation Sensor)

Micro-Orientation Sensor, CXM544

High Accuracy – Operates to 70°C
Calculates and Outputs Roll, Pitch, Yaw Data
Miniature Size: 0.80" x 0.80" x 4.6"
Digital Serial Output
Contains a 3-axis Magnetometer and a 3-axis Accelerometer
Applications

Borehole Logging
Buoy Orientation
Magnetic Compassing
Towed Sonar Arrays

The CXM544 sensor detects the Earth's magnetic field using a 3-axis magnetometer. The sensor computes a continuous measure of orientation using the 3-axis accelerometer as a gravitational reference field. The product uses the SoftSensor® architecture to compensate for temperature drift, alignment, and other errors. The CXM544 finds applications in oil well logging, marine systems, and magnetic compassing.
