strain gauges

Kingmach offers a range of strain gauges designed specifically for geotechnical and structural monitoring. Instead of one generic model, we supply different types to match the job: embedment strain gauges for concrete and grout, spot-weldable gauges for steel surfaces, and arc-weldable gauges where rugged attachment is needed. Each type is built around a common sensing technology—vibrating wire or electrical resistance—chosen for long-term stability and noise immunity. The vibrating wire models, for example, give frequency-based readings that travel long cable runs without signal loss, which is practical for dam, foundation, or tunnel monitoring. Resistance gauges are more suited for dynamic measurements or tight spaces where quick response is key.\n\nMany of our gauges include built-in temperature sensors for correction, and we can supply them with a variety of cable lengths and connector options to fit your data logger setup. Customization is a big part of what we do. If a standard gauge doesn’t quite match the reinforcement bar diameter, the concrete mix, or the mounting surface, we can adjust the gauge length, protection, or mounting method. This reduces installation headaches and data gaps.\n\nBecause we also make companion readout units, data loggers, and other geotechnical sensors, the strain gauges integrate smoothly into broader monitoring networks. We’ve seen them used in everything from bridge pier strain monitoring during construction to long-term crack movement studies on tunnels. When you get in touch, our support team usually asks about your project details first—material, environment, required accuracy—so we can help you pick the right gauge, not just the one in stock.
