VW Crackmeter
The Sanlien VW Crackmeter is designed for precise crack measurement. Comprising a vibrating wire and a stainless steel tension spring, this instrument ensures reliable, long-term monitoring even in harsh conditions.
With a special 4-core shielded cable, the VW Crackmeter maintains accuracy, unaffected by variations in cable length. As cracks open or close, the connecting rod shifts within the transducer body, altering the spring tension and modifying the resonant frequency of the wire to deliver precise readings.
