Vibrating Wire Strain Gauges for Bridge, Tunnel & Dam Monitoring: Complete Selection Guide
The global construction industry is experiencing a massive surge in large-scale infrastr...
Compression Canister Load Cells That Fit Your Jobsite
compression canister load cells
Measuring anchor forces in a tunnel or monitoring rock bolt loads in a mine—these tasks demand sensors that can handle harsh conditions without drifting over time. Compression canister load cells have become a standard choice for such applications, and at Kingmach we build them with the practical needs of field engineers in mind. Instead of exotic materials or complex setups, our focus is on reliable strain gauge design, robust sealing, and easy integration with standard readout equipment. Whether you’re working on a temporary excavation support or a long-term dam safety project, the cell needs to deliver repeatable data year after year. We offer custom ranges and cable lengths, and our technical team can help match the sensor to your specific load range and environmental constraints.
Technical Detail
Configured around process stability, mold life, and long-term uptime.
Kingmach compression canister load cells are built around a proven strain gauge design, housed in a sealed stainless steel body that resists moisture and dust ingress—common challenges in underground and outdoor installations. The central hole allows the cell to be placed directly on an anchor bolt or tendon, measuring the compressive force without needing additional adapters in many setups. Available in capacities from a few hundred kN up to several MN, they can be matched to project specifics. We use temperature-compensated gauges to minimize drift, and the cells can be paired with our portable readout units or integrated into existing data loggers via standard 4-20 mA or mV/V outputs. Customization is a core part of our service: we often adjust cable lengths, provide mounting flanges for uneven surfaces, or configure redundant measurement circuits for safety-critical dams. Our global distribution network means you can get a unit shipped to your site quickly, and our engineers offer guidance during installation and troubleshooting. For projects that require traceability, each cell comes with a calibration certificate referencing our in-house testing equipment. While we don’t compete on being the cheapest, the mid-range pricing reflects a balance between performance and budget that suits many consulting firms and government contractors.

Common technical questions
What are the typical load capacities available for compression canister load cells?
We offer cells ranging from about 200 kN up to 5 MN as standard, but higher capacities can be customized. The right capacity depends on your anchor or bolt design load—it’s best to select a cell that operates within 20–80% of its full scale for optimal accuracy.
Can these load cells be used in water-filled boreholes or submerged conditions?
Yes, our canister cells are sealed to IP68 in most configurations, so they can handle temporary submersion. For long-term underwater use, we can add extra potting and cable protection. Just let us know the expected water head and duration during ordering.
How do I connect the load cell to my existing data logger?
Standard output is a 4-20 mA current loop or mV/V signal, which works with most geotechnical loggers. We include a wiring diagram and calibration sheet with each cell. If you need a different connector or protocol, we can often modify the termination at the factory.
Do you provide calibration certificates, and is recalibration service available?
Every cell ships with a calibration certificate traceable to our in-house reference. We recommend recalibration every 2–3 years for critical measurements. You can send the cell back to us, or we can guide your local lab on the procedure.
What kind of mounting accessories do you supply with the cell?
We typically include a pair of loading platens or spherical seating plates to ensure even load distribution. Custom flanges, centering rings, or adapters for specific bolt diameters can be quoted based on your drawings. We can also supply dummy cells or simulators for system checks before installation.
