Description

The BWSENSING LWHD-WM400 Wireless Tilt Sensor employs a high-stability MEMS accelerometer core to provide precise three-axis inclination measurements. Its advanced signal conditioning ensures minimal temperature drift (±0.001°/°C) and cross-axis error, delivering reliable data for structural health monitoring. The sensor outputs data via a wired interface at up to 100Hz or transmits wirelessly via LoRaWAN at configurable intervals down to 0.1Hz.

Engineered for harsh environments, the unit features a ruggedized enclosure with excellent electromagnetic compatibility (EMC) and high shock resistance, making it suitable for permanent installation on bridges, tunnels, towers, and retaining walls. The integrated LoRaWAN module facilitates integration into wide-area networks (WAN) for centralized data collection and analysis, eliminating the need for complex cabling.

Key Features

  • Triaxial MEMS inclinometer with ±60° full-scale range on X, Y, and Z axes.
  • Industry-leading 0.005° to 0.007° accuracy and 0.001° resolution.
  • Dual-output capability: high-speed wired output (up to 100Hz) and low-power LoRaWAN wireless transmission.
  • Robust construction with 2000g shock rating and compliance with GBT17626 EMC standards.
  • Ultra-low power design supporting a typical operational lifespan of up to 10 years on a single battery.
  • Integrated magnetic switch for convenient device wake-up and configuration.
  • High insulation resistance (≥100 MΩ) for safe operation in electrically noisy environments.
  • Compact form factor (105.2 x 85 x 67 mm without antenna) for versatile mounting.

Applications

  • Structural health monitoring (SHM) for bridges, dams, and high-rise buildings.
  • Tilt and settlement monitoring of tunnels, retaining walls, and slopes.
  • Precision alignment and inclination measurement for industrial machinery and platforms.
  • Remote monitoring of transmission towers, wind turbine foundations, and solar tracker structures.
  • Geotechnical instrumentation for landslide early warning systems and infrastructure projects.

Frequently Asked Questions

What is the communication protocol and range of the LWHD-WM400 sensor?

The sensor uses the LoRaWAN protocol for long-range, low-power wireless communication. Its effective range depends on the local gateway network and environmental factors but typically covers several kilometers in open areas. It supports standard LoRaWAN network servers for integration into wide-area monitoring systems.

How is the sensor powered and what is its expected operational lifespan?

The LWHD-WM400 is powered by an internal, long-life battery designed for up to 10 years of operation. This is achieved through ultra-low-power electronics and configurable, low-frequency data transmission rates via LoRaWAN. The device also features a magnetic switch to conserve power during transport or storage.

Can this sensor provide real-time data, and what are its output data rates?

Yes, it offers dual output modes. For real-time, high-speed data, the wired interface supports output frequencies up to 100Hz. For wireless monitoring via LoRaWAN, the transmission rate is configurable but is typically set to a lower frequency (e.g., 0.1Hz) to optimize battery life, making it ideal for periodic remote monitoring rather than high-speed streaming.

Is the sensor suitable for permanent outdoor installation on civil structures?

Absolutely. The LWHD-WM400 is built with a rugged industrial design, featuring high shock resistance (2000g) and compliance with electromagnetic compatibility (EMC) standards. Its housing is designed for outdoor use, protecting the internal electronics from environmental factors, making it ideal for permanent installation on bridges, towers, and other critical infrastructure.

What is the process for calibrating and configuring the sensor?

The sensor is factory-calibrated, and its high-stability MEMS design minimizes long-term drift. Field configuration, such as setting the LoRaWAN transmission interval or device parameters, is typically performed via a dedicated configuration tool or software provided by BWSENSING, often utilizing the integrated magnetic switch for mode entry.
