NTRODUCTION
RST's RSTAR Affinity Tilt Logger is a high precision autonomous 3 axis
inclinometer capable of detecting deflections as small as 0.0005°.
NOTE: In the context of RSTAR Affinity Tilt Logger, "tilt" and "inclination" are
interchangeable.
Constructed with a robust and compact design featuring IP68 weatherproofing,
the Affinity Tilt Logger is an ideal choice for a variety of challenging geotechnical
environments.
The Logger uses a primary triaxial MEMS accelerometer sensor that captures
accurate tilt and inclination data. Additionally, it is equipped with a secondary
sensor for event detection, which intelligently adjusts the data sampling rate in
response to significant, sudden external events such as earthquakes,
landslides, and other severe structural failures.
RST provides two sensor options: high vibrations railways and standard. The
high vibration sensor is used in environments where there are intense, short-
duration vibrations. This includes scenarios such as installation next to railway
tracks or near activities like sheet piling. The high vibration sensor is designed
for compliance with high vibration and shock environments, while maintaining
high tilt precision and temperature offset performance.
Providing both measurement and data logging capacity, the Affinity Tilt Logger
integrates seamlessly with the RSTAR Affinity Data Platform, enabling real-time
data insights, analysis, and alerting. Data from the Affinity Tilt Logger is
wirelessly transmitted to the RSTAR Affinity Gateway via LoRa technology and
stored in the cloud, allowing users to access their data from anywhere in the
world. The Logger is equipped with a long-lasting battery and can operate for
years autonomously. If necessary, the battery is field-replaceable without losing
measurement continuity.
With options for internal and external antennas, as well as horizontal and
vertical mounting, it provides flexibility to suit diverse monitoring requirements.
At 40mm (1.6 in) height, it is also well suited for applications requiring a low-
profile sensor.
The Affinity Tilt Logger is perfectly suited for applications requiring careful
monitoring of structural stability or machinery alignment, providing crucial data
that supports technical assessments and decision-making.
