Weldable Strain Gauges
Field-Ready Strain Gauges for Harsh and Unprepared Surfaces
Weldable strain gauges from Proact IMS are engineered for environments where traditional adhesive bonding is either unreliable or impractical. These gauges can be spot-welded directly to metallic surfaces, making them ideal for outdoor, corrosive, and high-vibration applications such as bridges, pipelines, mining equipment, and heavy machinery.
Built with rugged stainless-steel carriers, hermetically sealed elements, and strain-relieved cabling, these sensors are designed for long-term monitoring, even under extreme mechanical and environmental stress.
Key Features
- No adhesive required – attached via weld tabs using standard resistance or arc welding
- Resistant to moisture, oil, dust, and vibration
- Available in linear, biaxial, and rosette configurations
- Backed with stainless steel or Inconel for mechanical robustness
- Can be installed on rough, unclean, or painted surfaces with minimal prep
- Suitable for both temporary and permanent installations
-
