Vibrating Wire Jointmeters
The JM jointmeters consist of a vibrating wire displacement transducer inside a telescoping stainless steel housing. Jointmeters are mounted onto or embedded in a structure, such that its active gauge length spans the crack or joint to be monitored. The JM-S surface jointmeter is attached to the surface of the structure using groutable or bolt-on anchors. It is attached to the anchors with ball joints at the ends of the sensor, which compensate for any anchor misalignment. The JM-E embedment jointmeter is embedded in concrete structures such that its active gauge length spans the construction joint to be monitored.
