Wuhan Zhongdi Hengda - Universal Crack Gauge
(1) Product Introduction
The PLF01 Universal Crack Gauge has built-in displacement sensors, tilt sensors, and acceleration sensors, and is suitable for monitoring work in various working scenarios such as landslides, dangerous rock collapses, and dams. Its small size, low power consumption, and easy installation meet the monitoring needs in complex field environments. The device supports setting early warning thresholds, and once the threshold is exceeded, it can automatically activate the acoustic-optic alarm function.
(2) Product Features
1) Small size, multi-function, no need for integration, high precision, and high stability;
2) Simple installation and rapid deployment; suitable for harsh environments;
3) Good long-term stability;
4) Supports remote upgrades, early warning, and parameter configuration, and supports encrypted data collection;
5) Real-time data upload, adjustable reporting frequency, automatic additional reporting when thresholds are triggered, and local early warning is activated in real time when thresholds are reached;
6) Has perfect lightning and overvoltage protection, good waterproof sealing, with a protection level of ≥IP67;
7) Can realize local networking with early warning broadcast;
8) Supports protocols such as HTTP and MQTT of the Technical Guidance Center for Geological Hazards.
