High precision wear-resistant linear resistance is used as the core component of PT124B-LF Crack Meter. The main body is a strip linear resistor and the moving part is a metal conductor with low resistivity. Displacement is measured by measuring the position of the metal conductor on the linear resistor.
- Small size and easy installation;
- Single unit, no separate parts;
- No additional data converter needed;
- Easy maintenance;
The crack meter is used to measure displacement of building, tunnel, subway, wind tower and signal tower constructions and maintenances.
