Fluxgate Magnetometer FGM-301
The same high precision magnetometer that is an exceptional magnetic heading reference sensor for our AHRS units is also available as a stand-alone analog magnetic sensor. Its high accuracy makes the Watson FGM an ideal choice for inertial navigation, geological mapping, and heading reference.
Features:
- High Accuracy
- High Resolution
- High Reliability
- Low Noise
- Low Power
- Small Size and Weight
- Two Year Warranty
- Engineering Support
Description
The FGM-301 is the best product for measuring DC and low frequency magnetic fields in three dimensions. This is a compact magnetic sensing device suitable for a wide variety of magnetic field measurement applications. Being an analog sensor, the FGM-301 provides high resolution and low signal delay. This product is far more stable and linear than magneto-resistive and magneto-inductive magnetometers.
Watson Industries has been developing state-of-the-art fluxgate magnetometers for almost thirty years to provide the FGM-301. As a result, this magnetometer is relied on for precision measurements in very critical projects around the world, including near the north and south poles.
