Enhance structural monitoring with the VW Crackmeter— a durable solution designed for precise crack measurement. Comprising a vibrating wire and a high-quality stainless steel tension spring, this instrument ensures reliable, long-term monitoring.   With a special 4-core shielded cable, the VW Crackmeter maintains accuracy, unaffected by variations in cable length. Ideal for embedding in harsh conditions, it excels in prolonged monitoring periods. As cracks open or close, the connecting rod shifts within the transducer body, altering the tension on the spring and modifying the resonant frequency of the wire.
