About the 701-2A/2B (4X) Weatherproof Platform Tiltmeter 

– high-precision 2-axis tiltmeter for harsh environments

The 701-2(4X) Weatherproof Platform Tiltmeter is a high-precision analog 2-axis tiltmeter designed for applications where weather protection and measurement stability are critical. With resolution down to 1 µrad (or better) and IP65 / NEMA 4X protection, it is well suited for humid, hot, or corrosive environments.

Thanks to three integrated Invar leveling feet, the tiltmeter can be installed quickly and repeatably on any horizontal surface. Output is a stable ±8 VDC (or ±16 VDC differential)—ideal for accurate data acquisition and long-term monitoring.

Key benefits

• Weatherproof (IP65 / NEMA 4X) for outdoor use and demanding environments
• 2-axis measurement (X/Y) + temperature channel for comprehensive monitoring
• High accuracy: resolution down to < 1 µrad (701-2A) or 1.0 µrad (701-2B)
• Easy installation with 3 Invar leveling legs
• Robust integration: ±8 VDC output (±16 VDC differential), 3 m shielded multicore cable with connectors

Typical applications

• Volcano monitoring
• Geotechnical & structural monitoring (e.g., deformation)
• Bridge deflection monitoring
• Precision metrology
• Radar platform leveling
• Any application requiring enhanced weather protection
