Strain Gauges for the Real World—Not Just the Lab
You know the routine: a strain gauge works perfectly on the bench, but bolt it to a pile 20 meters underground and see what happens. Moisture, temperature swings, uneven surfaces—lab specs don’t mean much out there. That’s the gap we focus on at Kingmach. We’ve been supplying geotechnical monitoring tools long enough to understand that strain measurement isn’t just about accuracy on paper; it’s about repeatability in messier conditions. Our strain gauges are designed for soil nail pull tests, pile static load tests, tunnel lining stress analysis, and similar fieldwork. Customization is part of the deal—whether you need a specific gauge length, tailored lead wire, or a particular bonding method. We maintain a wide product range, but we’d rather talk about what your project actually needs than push a catalog. With a global distribution network and engineers who can walk you through installation or troubleshooting, we try to make strain monitoring less of a headache. If you’re looking for strain gauges that survive the transition from datasheet to site, we should talk.
Technical Detail
At Kingmach, strain gauges are not an afterthought—they’re one of the core tools we supply to geotechnical and structural monitoring projects. Our catalog covers the usual suspects: foil type, wire type, embedment gauges for concrete, spot-weldable versions for steel structures, and specialty gauges for soil and rock applications. What sets our offering apart isn’t a single feature; it’s the ability to adapt when standard catalog items don’t fit. Need a gauge with a non-standard resistance or an extended temperature range? We’ll configure it. Working in a high-humidity environment and need sealed leads? We handle that. The range isn’t limited to strain gauges alone; we also provide the complementary readout instruments and data loggers, so the measurement chain stays consistent. Our technical support team commonly helps clients with strain gauge selection, bonding procedures, and signal conditioning advice—stuff that matters when you’re instrumenting a diaphragm wall or a rock bolt and can’t afford rework. Rather than promise everything, we focus on what a geotechnical engineer actually needs: repeatable measurements, straightforward installation, and support that doesn’t disappear after the sale. Our distribution network spans multiple continents, making replacements or additional units less likely to delay a project. If you’re familiar with the usual strain gauge brands, you’ll find our pricing sensible, especially when customization is required.

Yes, we regularly supply custom resistance values. Just let us know the gauge factor and other electrical specs you need.
We offer sealed and encapsulated options specifically for high-moisture or submerged environments. The lead wire exit can also be customized to prevent water ingress.
Absolutely. Our application engineers can walk you through surface preparation, adhesive selection, and protective coating steps—whether you’re following a standard like ASTM or adapting to site conditions.
Typical strain gauges for pile tests are often considered consumable. We can discuss reusable vs. disposable options based on your test protocol and budget.
It varies, but we try to accommodate smaller orders for specialized projects. There’s no rigid MOQ when it’s a genuine requirement.
Share your product type, target capacity, and application requirements. Our team can review the details and recommend a practical next step.
