Tiltmeter

The Worldsensing Tiltmeter is a 3-axis wireless sensor engineered to measure relative inclination changes, either on the ground or in structures. It provides a cost-effective and reliable solution for monitoring track geometry in railway projects in combination with other geospatial monitoring techniques.
With battery life of up to 25 years and a communication range reaching 15 km, the Tiltmeter ensures long-term, maintenance-free performance in remote or hard-to-access sites. Its robust design and high precision make it ideal for continuous monitoring of structural deformation, ground movement, and differential settlement across slopes and infrastructure.
