Overview and use the product in a common internal mechanical separation to a electrical components, can be converted into mechanical power output of displacement, so that it can make use of mechanical measuring dial indicators (machine), while another sensing effect (electrical). Machine and electrical data comparison check of each other, and a separate application, does not affect their work performance. It implements the mechanical separation of telemetry, and as more displacement measurement data acquisition creates conditions, large relief operations staff of labor productivity.
The high precision products, small, easy to use, it can be widely applied in civil engineering and architecture, and hydropower, railway bridge, aerospace, aviation, shipbuilding industry, mining, mechanical engineering, construction and testing of teaching and scientific research.
Structure and principle of measuring rod and machine testing of gear and and electrical components, cantilevered connection bar when logging, measuring rod displacement through the spring to cantilever the Reed on the strain gauges and a resistance to change, produces output. (See Figure 1)
