Surface Strain Gauge
Measure strain on the structures you can reach
BEAM-SG-W / SG-WX (weldable) · BEAM-SG-S / SG-SX (groutable)
When you need strain from a steel strut, sheet pile, pipeline or exposed concrete face, mount the gauge directly to the structure and let the change in wire frequency reveal the load path.
One sensing element, two ways to mount it
The SG-W arc-weldable gauge is built for structural steel. The SG-S version uses groutable anchors for concrete, rock or timber surfaces.
The same vibrating-wire principle gives you a durable strain signal for construction, service-life monitoring and load testing, with an integral thermistor for temperature correction.
Built for the places where change matters.
Use the sensor where you need a stable, long-term view of the parameter at risk.
Mount to the surface. Capture the change.
For SG-W, weld or bolt the end blocks to the cleaned steel surface at the correct gauge spacing. For SG-S, drill for the groutable anchors, set them and mount the gauge across them before logging a baseline.
Designed for the long read.
- Accurate, long-term stability
- Robust and reliable
- Waterproof O-ring seals
- Manual or remote reading
- Compression or tension range
- Integral thermistor

The instrument is only the beginning.
Connect the sensor to an Ackcio BEAM-VW node and carry the measurement through Mesh to the monitoring view.
Strain-gauge clusters typically suit BEAM-VW-S8. A single check gauge can run on BEAM-VW-S1.

Readings arrive in the Snape dashboard as live time-series data in Micro-strain (με). Check network health, node status and threshold conditions from the same view.

SG-W is the arc-weldable option; SG-S is the surface-mount option for steel or concrete surfaces. X suffixes denote one-piece integrated bodies.
