We professionally apply strain gauges to components, sensor carriers, and test specimens—from substrate preparation and bonding to wiring/bridge connection, temperature compensation, sealing, and documentation.
This provides you with stable, low-interference, and reproducible measurement signals—for testing, test benches, and series applications.
Strain gauge application for precise force and strain measurement – from a single source
We plan and implement the professional application of strain gauges on components, sensor carriers, and test specimens – including substrate preparation, bonding, wiring, temperature compensation, protective construction, testing, and documentation. This provides you with stable, reproducible measurement signals for testing, test benches, and series production.
Why choose DISA for your strain gauge application?
- Measurement technology and application expertise: Positioning, alignment, and bonding of strain gauges – tailored to the material, load case, and measurement objective.
- Reproducible quality: Standardized processes for preparation, bonding, curing, protection, and electrical testing.
- Low-noise signals: Bridge circuits, cable routing, shielding, and EMC-compliant design minimize noise and drift.
- Documented & audit-proof: Application protocols, photos, wiring/bridge diagrams, characteristic values – ready for QA and acceptance.
- Integration & handover: Complete measuring chain with connectors, cables, amplifier parameters, and functional verification.
Our services
Application consulting & positioning
Determination of measuring locations, fiber alignment, grid dimensions, grid length, and protection concept – tailored to geometry, material, and load.
Substrate preparation & bonding
Cleaning, grinding/blasting, activation; adhesive selection (e.g., cold/hot curing, high temperature), defined contact pressure and curing.
Wiring & bridge circuits
¼, ½, and full bridge, 3/4-wire technology, soldering/clamping technology, connectors; zero point adjustment, sensitivity and direction testing.
Temperature compensation
Compensation strain gauges, dummy bridge, material pairing, and cable concepts to reduce thermal effects and long-term drift.
Protection & sealing
Primary/secondary protection against moisture, chemicals, and mechanical damage (e.g., coatings, casting resins, caps), strain relief, and kink protection.
Cable management & EMC
Guided, shielded cable routing, grounding concept, filters; robust connectors for laboratory and production.
Testing, calibration & documentation
Resistance/insulation/bridge testing, shunt calibration, functional verification; application report with photos, diagrams, and parameters.
