Features of PANDAS-3R®

Ultra-Low Power Wireless Accelerometers

The heart of our system, these 3-axis wireless accelerometers are designed for longevity, only requiring battery replacement once every two and a half years.

Precision GPS Location Stamps

Every reading is accompanied by an accurate GPS stamp, enabling maintenance personnel to identify problematic locations in the third rail infrastructure.

User-Adjustable Thresholds

Two levels of threshold limits ensure timely alerts and comprehensive data. Low threshold captures impact events, while the high threshold sends immediate alerts for more significant impacts.

Near-Instantaneous Alerts

Critical impact events trigger real-time alerts sent via email and/or SMS, ensuring stakeholders stay informed.
