Vibrating wire crack meter

Vibrating Wire Joint Meter - Displacement Type of Engineering Monitoring Instrument

It is permanently embedded in or on the surface of hydraulic structures or other concrete structures, used to measure the opening and closing degree (deformation) of expansion joints or peripheral joints of structures, and can simultaneously measure the temperature at the embedding point. By adding supporting accessories, it can form instruments for measuring linear deformation such as bedrock displacement meters, surface crack meters, and multi-point displacement meters.

1. Scope of Application   

The vibrating wire joint (displacement) meter is permanently embedded in or on the surface of hydraulic structures or other concrete structures, used to measure the opening and closing degree (deformation) of expansion joints or peripheral joints of structures, and can simultaneously measure the temperature at the embedding point. By adding supporting accessories, it can form instruments for measuring linear deformation such as bedrock displacement meters, surface crack meters, and multi-point displacement meters.

Technical Parameters

Product Features

Miniaturized structure with an outer diameter of only Ф20mm, making it applicable to a wider range of spaces; High-sensitivity output, with full-scale output reaching up to 4000 counts; Designed and manufactured with high quality to ensure long-term stability and reliability; All-stainless steel structure with high waterproof performance; Adopts a more stable and reliable vibrating wire working principle, with digital output, so the measured value is not affected by cable length; Can also measure the temperature at the embedding point, and the measured value can be accurately corrected;

Precautions

1Vibrating Wire Joint Meter - Displacement Type of Engineering Monitoring Instrument should operate within the rated measuring range;

2 The lead-out cable of the instrument can reach up to 1000 meters (purchased separately). If no special instruction is given when the user places an order, the instrument will be delivered with a 1.5-meter cable;

3 When extending the cable according to on-site needs, ensure the waterproof sealing of the joint is reliable;

4 If the instrument is stored unused for more than 12 months, it should be recalibrated before use
