PNI RM3100 Geomagnetic Sensor
PNI Sensor’s RM3100 Geomagnetic Sensor is the highest performance sensor in its class with over 10 times better resolution and over 20 times lower noise than the leading Hall Effect sensor. It makes precise magnetic field measurements, which enables accurate calculation of heading and orientation.
RM3100 eliminates any “blur”in your magnetic field measurements making distortion error correction a snap, and ultimately allowing you to easily and accurately calculate absolute orientation and heading.
