SK-SP Vibrating Wire Steel Plate Strain Gauge
Short Description:
Overview
The Enviko SK-SP vibrating wire steel plate strain gauge monitors strain on steel structures such as pipelines, steel frames, steel sheet piles and bridges. It is fixed to the steel with welded mounting bases and measures strain as the stress in the steel changes. A built-in temperature sensor records ambient temperature, and a smart chip can be added on request.
Key Features
- Stainless steel construction with integrated bellows strain body
- Resistant to rotation, bending, impact and drops
- Follows the deformation of the steel without disturbing the original stress field
- Sealed design with grounding for lightning protection
- Optional carbon steel or stainless steel protective cover
- Built-in temperature sensor; optional smart chip
Applications
- Steel structures of hydraulic and other buildings
- Pipelines
- Steel sheet piles
- Steel bridges
