Vibrating Wire Joint Meter - Displacement Type for Engineering Monitoring Instruments
It is long-term 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 long-term 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.

Product Features
Compact structure with an outer diameter of only Ф20mm, making it applicable to a wider range of spaces; High sensitivity output, with full-scale output up to 4000 counts; High-quality design and manufacturing ensure long-term stability and reliability of the product; All-stainless steel structure with high waterproof performance; Adopts a more stable and reliable vibrating wire working principle, with digital output, and the measurement value is not affected by cable length; Can also measure the temperature at the embedding point, and the measurement value can be accurately corrected;
Notes
1Vibrating Wire Joint Meter - Displacement Type for Engineering Monitoring Instruments should operate within the rated measurement range;
2 The lead cable of the instrument can reach 1000 meters (purchased separately). If no instructions are given when ordering, the product will be delivered with a 1.5-meter cable;
3 When extending the cable according to on-site needs, ensure the waterproof sealing at the joint is reliable;
4 If the instrument is stored unused for more than 12 months, it should be recalibrated before use
