Deskripsi produk

High Precision Gyrocompass North Finder System for True North Detection and Direction Measurement

The NF701A Fiber Optic Gyro North Finder is a rugged directional survey instrument for underground mining and tunnel boring operations. Its FOG-based north seeking technology provides reliable azimuth data in magnetically noisy underground environments where conventional compasses fail, operating flawlessly from -40 to +70 deg C.

Dimensions

115 x 90 x 110 mm

Technical Specifications

North seeking time: ≤ 3 minutes
North seeking accuracy (1 sigma): ≤ 0.3 deg (NF701A); ≤ 0.5 deg (NF701B)
Horizontal accuracy: ≤ 0.05 deg (1 sigma)
Circumference: ≤ 0.5 deg (1 sigma)
Weight: ≤ 2 kg
Power supply: DC 12V ~ 24V
Power consumption: 15 W (peak)
Interface: RS422
Working mode: Automatic self-check on power-up, controlled north seeking via upper computer

Environmental Requirements

Operating temperature: -40°C to +70°C
Storage temperature: -55°C to +85°C
Humidity: Relative humidity less than 95%

Reliability

MTBF ≥ 1000 hours
MTTR ≤ 30 minutes

Ideal Applications

Tunnel Boring Machine Guidance: Precise heading for TBM navigation in long-distance tunnel projects
Underground Mine Surveying: Magnetic-free north reference for drift and shaft alignment
Coal Mine Development: Reliable azimuth data for ventilation shaft and gallery planning
Subway Construction: Accurate directional control for urban metro tunnel boring
Hydroelectric Tunnel Projects: North reference for water diversion and penstock tunnel construction
