Survey Grade Fiber Optic Gyroscope 1.5 deg/h Bias for Geophysical Borehole Survey Equipment
The MFOG-24 is a survey-grade fiber optic gyroscope optimized for geophysical borehole survey and downhole measurement applications. Its slim phi24x39mm cylindrical form factor fits standard survey tool housings for oil and gas well logging.
Utilizing Sagnac effect technology, the MFOG-24 provides 1.5 deg/h bias stability essential for accurate borehole trajectory measurement. The solid-state design withstands the high shock and vibration environment encountered during downhole deployment operations.
- 1.5 deg/h bias stability for accurate borehole trajectory measurement
- Angular rate range: +/-500 deg/s covers all downhole rotation scenarios
- Slim phi24x39mm form factor fits standard MWD and gyro survey tools
- Operating temperature: -40 to +65 deg C (extended range available)
- 20g vibration resistance for harsh downhole deployment conditions
- Low 1.5W power consumption extends battery life in downhole tools
