FTJN-3 Engineering Structure Deflection and Settlement Tester (Non-contact, CCD Acquisition)
Working Principle
The FTJN-3 engineering structure deflection and settlement tester is fixed on the tested structural body. An industrial CCD is installed inside the tester. Use a thin steel wire with a diameter of 0.3~0.6㎜ to pass through the tester, and at the same time, pull and fix both ends of the steel wire with constant force on the stationary objects that do not displace outside the tested body. Adjust the gap so that the steel wire passes through without touching the tester. Taking the steel wire as the stationary reference benchmark, the internal CCD of the deflection tester is used to collect the relative displacement change between the steel wire and the tester, so as to measure the deflection value of the tested structural body.
Main Technical Parameters
1.Measuring range: ±30mm (can be expanded according to user needs);
2.Minimum resolution: 0.01mm;
3.Indicating error: ±0.1mm;
4.Repeatability accuracy: ≤±0.05mm;
5.Communication method: RS485/RS232/CAN/Wireless transmission;
6.Working environment: Temperature: -40~+60℃; Humidity: <90% RH;
7.Working voltage: DC+8~+18V.
Advantages: The deflection tester uses CCD non-contact measurement of the stationary steel wire, which reduces the instrument error caused by the change of the steel wire position due to contact friction and other transmission mechanisms, and its accuracy is far higher than that of similar products.
