flexible strain gauge

Kingmach’s flexible strain gauges use a thin, flexible base that can wrap around small-radius curves – a common headache in tunnel steel arch monitoring or concrete shell measurement. The construction resists moisture and dust, which matters when instruments stay buried in grout or exposed to weather. Typical uses include strain measurement on concrete, steel, and rock surfaces in civil and mining projects. For instance, during tunnel driving, these gauges attach to lattice girders and feed back real-time load changes, while ordinary spot-welded strain foils often fail in damp environments. Bridge expansion joint monitoring is another fit, as the gauge’s flexibility accommodates small structural displacements without cracking. Kingmach supplies different gauge lengths and can customize mounting fixtures for odd-shaped cross-sections. Our engineers help you choose the right configuration and provide data acquisition options – from standalone loggers to cloud-connected systems. With a global distribution network, we support projects from feasibility study to operation, including calibration advice and onsite guidance if needed.
