High-speed Wireless Transmission Inclinometer
The High-speed Wireless Transmission Inclinometer series is a compact, intelligent tilt monitoring solution designed for long-term structural health and industrial equipment monitoring. Supporting multiple wireless communication options—including 4G, proprietary wireless, and ultra-low-power LoRaWAN—the series delivers reliable 3-axis tilt (and optional acceleration) data with long battery life, remote configuration, and stable transmission for distributed, real-time measurement applications.
The DTFG-WM400 is a 4G-enabled wireless inclinometer that outputs 3-axis tilt and 3-axis acceleration, powered by a large-capacity lithium battery (with optional rechargeable version). With an upload rate of once per hour, it operates continuously for up to 3 years. It supports 4G full-network transmission, cloud connectivity via TCP/UDP, and remote configuration for sleep timing and reporting intervals, making it ideal for long-distance, real-time monitoring.
