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 audible and visual alarm function.
(2) Product Features
1) Small size, multi-function, no need for integration, high precision, and high stability;
2) Easy installation and rapid deployment; suitable for harsh environments;
3) Good long-term stability;
4) Supports remote upgrading, 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 comprehensive lightning surge protection, good waterproof sealing, and protection level ≥ IP67;
7) Can realize local networking with early warning broadcasting;
8) Supports protocols such as HTTP and MQTT of the Technical Guidance Center for Geological Disasters.
