The Model 545 series sensors utilize a solid state “strapdown” configuration that avoids the performance limitations of typical gimbaled systems and offers improved reliability.

A 3-axis fluxgate magnetometer and a 3-axis MEMs accelerometer are combined with digital signal processing electronics and fully integrated within a small diameter pressure rated housing.

The digital signal processor samples and converts the internal sensor signals to 16-bit digital data and automatically compensates for any temperature and misalignment effects.

Factory calibration of scale factor, bias and misalignment angles is achieved by placing the instrument in high precision fixtures that apply rotation and magnetic fields. Scale factor and bias coefficients are measured over the operating temperature range of the sensor.

The calculated roll, pitch and azimuth angles are provided on a bi-directional RS232 serial data link and is user programmable for data transfer rates of up to 38400 baud.
