FTLF-5 Intelligent Crack Monitor
FTLF-5 intelligent crack monitor is used for long-term fixed-point monitoring and recording of key crack changes at high altitudes and inaccessible structural locations. The monitor can continuously measure and record the changes of cracks over time and the external ambient temperature. The change value of the fracture clearly reflects the change trend of the crack.
The instrument monitors and stores crack change data in real time. The USB interface can download the stored crack width value and temperature value to the handheld PDA or computer terminal at any time and draw the crack development trend curve by supporting software.
1. Integrated crack sensor, temperature sensor, measuring instrument and memory;
2. Outdoor environment design, well sealed, the instrument shell is sturdy and durable, and no manual intervention is required once it is set to start;
3. The displacement sensor can be installed on hard-to-reach areas or cracks in high places at one time, and its measurement / recording part is connected to the ground or easily accessible position by cable, which is convenient for future parameter setting, real-time data viewing, data download and battery Manual operations such as replacement;
4. The built-in memory in the measurement / recording part can record the width change data of the crack for a long time;
5. The standard USB interface is convenient for directly downloading the recorded data to a handheld PDA or computer terminal, and simple and practical data setting, acquisition and analysis software.
6. Wireless transmission of data can also be realized, making instrument control and data viewing more convenient.
