Product overview

The Archimedes Innovation ANF-301B MEMS North Seeker continuously measures changes in inclination, tool face and azimuth, together with the carrier’s angular and linear motion parameters. Designed for resource exploration applications including coal mining and petroleum, it incorporates shock absorption and high-temperature resistance for operation in harsh environments. Zero-bias compensation helps maintain heading accuracy over time, while configurable homing time and installation misalignment angle compensation support its measurement functions.

The ANF-301B combines a ±200 °/s gyroscope measurement range with a ±30 g accelerometer measurement range. Its body measures Φ31.8 × 85 mm and weighs 145 ± 10 g. Operating from a 5~12 V supply, it consumes ≤2 W in steady state, starts in ≤2 s and supports a maximum update rate of 200 Hz. Its operating temperature range is -40 to +120 °C, with shock resistance of 500 g / 1ms.
