TensionCam product offering
Product offeringCore offering
TensionCam Systems AB sells a patented IoT-based clamp-load measurement system for industrial bolt joints: specially designed nuts (M8 to M100, including inch sizes) with an integrated cavity, a sensor module that captures images of a precision-machined circle inside the cavity, and cloud-based analytics plus a mobile app/web portal that convert diameter changes into clamp load readings. The nuts can be paired with on-site diagnostics, installation services, and tailor-made variants so customers can verify and track actual clamp load on wind turbine blade bolts, bridge cable clamps, heat exchangers, flanges, and other critical bolted joints.
Product overview
TensionCam offers a patented nut, sensor, and IoT-based concept that provides total clamp load control for industrial bolt joints. The product portfolio consists of TensionCam Nuts (M8 to M100), the TensionCam Sensor Module, the TensionCam App, and the TensionCam Cloud/Web Portal. The nuts are specially designed with a cavity containing a precisely machined circle; when the sensor module docks into this cavity and captures images, the cloud-based algorithms analyze the circle's diameter changes to calculate clamp load. The system also offers services including Diagnostics & Analysis, On-Site Clamp Load Measurement, and Tailor-Made Nuts. The solution is designed for bolt joints in applications including wind turbines, bridges, industrial heat exchangers, pipe flanges, and electrolyzer stacks.

Products and services
- TensionCam Nuts Patented specially designed hex nuts (M8 to M100, including inch sizes) with an extended section featuring a small cavity bored into the cap and an 8mm precisely machined circle at the bottom, maintaining the mechanical properties of standard hex nuts while enabling image-based clamp load measurement at ±5% precision. Sold to enterprise customers in wind power, bridges and heavy industry.
- TensionCam Sensor Module Specialised sensor module with an image sensor that docks into the cavity of TensionCam nuts, captures images of the precision-machined circle, and transmits them to the TensionCam cloud via the mobile app for clamp load calculation. Sold as a unit to operators measuring TensionCam-installed bolt joints.
- TensionCam Cloud / Web Portal Cloud platform that analyses images captured by the sensor module using proprietary algorithms, calculates exact circle diameter and clamp load, displays Trend and Load Scatter diagrams for each individual bolt joint, and stores historical measurement data per NFC-tagged nut. Sold as the analytics layer of the TensionCam system to enterprise and government customers.
- TensionCam Mobile App User-facing mobile application that receives sensor data, displays calculated clamp load within seconds, alerts the operator when re-tightening is required, and serves as the on-site interface to the TensionCam cloud. Delivered to operators and inspectors using TensionCam nuts and sensor module.
- Diagnostics & Analysis Service Professional service providing an initial assessment of existing bolt joint problems and risks, helping enterprise customers understand their potential bolt joint issues before adopting TensionCam solutions. Pricing is scope-based and site-specific.
- On-Site Clamp Load Measurement Service Service for performing clamp load measurements on installed TensionCam nuts at customer sites during installation and across the operational life of the bolted joint, often delivered together with specialist installation partners such as Alticlimb AB.
- Tailor-Made Nuts Custom manufacturing service that supplies TensionCam nuts in all sizes from M8 to M100, including inch sizes and various special steel designations tailored to customer specifications and applications.

TensionCam competitors and assessment
Company assessmentDirect peers
- Kistler Group: Kistler manufactures piezoelectric and strain-gauge based sensors for measuring force, pressure, torque, and acceleration in industrial and laboratory applications. It is directly comparable to TensionCam as both companies commercialize force/load measurement technology applied to industrial mechanical assemblies.
- HBK (Hottinger Brüel & Kjær): HBK is a global leader in test, measurement, and force/torque sensing solutions, including load cells and strain-gauge instrumentation. It is a direct peer to TensionCam in delivering precise load and force measurement hardware used in mechanical and structural integrity applications.
- Sensor Technology Ltd: Sensor Technology specializes in non-contact torque and load measurement for industrial machinery using strain-gauge and telemetry technology. It overlaps directly with TensionCam's clamp-load monitoring concept applied to rotating and bolted mechanical systems.
- HYTORC: HYTORC is a leading provider of industrial bolt tensioning and tightening tools, including hydraulic torque wrenches and bolt tensioners used in mission-critical joints. It is comparable to TensionCam as both target the same industrial customer need of controlling bolt preload/clamp load.
- Manner Sensortelemetrie: Manner specializes in wireless, in-situ load and strain telemetry for rotating and stationary mechanical assemblies, including bolted joints. It is a direct peer to TensionCam in delivering digital clamp-load/force measurement hardware for industrial condition monitoring.
Broad incumbents
- Atlas Copco (Industrial Tools): Atlas Copco's Industrial Tools division supplies a broad range of assembly and bolting solutions including torque wrenches, nut runners, and quality assurance software. It competes with TensionCam in addressing industrial bolt joint quality, but as part of a much wider fastening and assembly portfolio.
- Stanley Black & Decker (Industrial Tools): Stanley Black & Decker's Industrial segment includes assembly technologies and torque-control solutions for OEM and field-service fastening applications. It is a broad incumbent peer to TensionCam, competing in industrial bolt tightening from a much larger tool-portfolio base.
- Nordson Test & Inspection: Nordson Test & Inspection provides precision measurement and inspection systems for industrial manufacturing, including force/displacement sensing. It is a broad incumbent peer to TensionCam in delivering industrial sensing and process measurement instrumentation.
Emerging players
- Nord-Lock Group (Superbolt): Nord-Lock and its Superbolt brand produce mechanical bolt-securing and multi-jackbolt tensioning solutions that ensure preload retention in bolted joints. They are adjacent peers to TensionCam, addressing the same clamp-load reliability problem with a different mechanical/structural approach.
Others
- SKF (Condition Monitoring): SKF is a global bearing and industrial rotating-equipment leader with a substantial condition-monitoring and predictive-maintenance portfolio. It is comparable to TensionCam as an enabler of asset-health monitoring in industrial infrastructure, though it does not specialize in bolt joint clamp load.
