2-axis tilt sensor / digital / wireless SenSpot™

Product catalog summary

Overview
SenSpot™ is a wireless, high-resolution 2D inclination/tilt sensor designed for structural integrity monitoring. It is particularly useful in applications such as bridge health monitoring, aerospace engineering, and automation technology. The device offers ultra-low power precision sensing and wireless communication, making it ideal for long-term, maintenance-free operation.

Benefits

Long battery life of up to 10 years.
Wireless communication eliminates the need for wiring.
Lightweight and easy to mount using flange or adhesive tape.
Adjustable sampling intervals ranging from 18 seconds to 10 minutes.
Long communication range of up to 1.0 km in free space.
2D measurement capability for comprehensive surface tilt monitoring.

Specifications

Operating range includes narrow, mid, and regular tilt measurements with varying degrees of precision and linear range.
High resolution and repeatability, especially in narrow and mid-range high-resolution tilt (HRT) modes.
Weatherproof with IP65 ingress protection, suitable for harsh environmental conditions.
Operates in temperatures ranging from -40°C to +65°C.
Compact dimensions for both transmitter and assembly.

Description
SenSpot™ offers a scalable solution for distributed structural integrity monitoring using proprietary technology for accurate measurement and wireless synchronization. It requires minimal installation effort and no maintenance for at least 10 years. The sensor is capable of detecting minute structural movements and temperature-induced expansions or contractions.

Installation and Dimensions
The SenSpot™ unit includes built-in tilt sensors that transmit data wirelessly to SeniMax™. Installation is recommended using screws and anchors, although VHB tape can be used on smooth surfaces. However, adhesive tape may affect measurement accuracy due to environmental changes. The device measures pitch and roll orientations, with specific dimensions provided for installation guidance.

Data Visualization
SenScope™ software displays high-resolution tilt measurements, providing detailed insights into structural movements.
