WxS981T-4030N1 NB-IoT Manhole Tilt Sensor
Safeguard your urban underground utility networks with the Polysense WxS981T-4030N1 NB-IoT manhole tilt monitoring sensor, engineered for long-term, maintenance-free deployment inside manhole covers
.
This robust NB-IoT sensor is built to operate on global cellular NB-IoT bands: B1/B3/B5/B8/B20 — the primary NB-IoT frequency band widely adopted, delivering stable, reliable cellular connectivity deep beneath pavement, even in challenging underground signal conditions.
Designed for the harshest subsurface environments, the WxS981T-4030N1 features an IP68 fully sealed enclosure. It reliably detects manhole cover tilt, shift and unauthorized opening over a 0° to 180° measurement range, with high precision of ±1°, instantly pushing alarm notifications to your cloud platform once abnormal movement occurs.
Ultra-low power consumption is at the core of this design. Powered by lithium battery, the sensor achieves an impressive battery lifespan of 3 to 5 years, eliminating frequent field battery replacement and cutting your on-site OPEX dramatically
Key features:
- Connectivity: NB-IoT cellular
- Supported Bands: B1, B3, B5, B8, B20
- Operating temperature: -20℃ ~ +70℃
Integrated FPC antenna for compact, easy mounting inside manhole chambers
Fully compatible with EN124 standard manhole cover installations
Ideal for water utilities, sewer networks, municipal road management, local councils and smart city integrators. Deploy this sensor to proactively identify displaced or stolen manhole covers, prevent road accidents, reduce public safety hazards, and transform reactive underground infrastructure maintenance into predictive, data-driven management.
