OPTICAL STRESS
MEASUREMENT
EQUIPMENT
Portable Strain Viewer PSV-100
Used for:
Visual inspection of stresses in glass and plastics
Application:
- Evaluation of temper in glass
- Verification of annealing
- Observation of strains in moulded products
- Detection of weld and flow patterns
- Examination of flow patterns and gate efficiency
- Identification of irregularities due to mould deficiencies or temperature gradients
Residual stress can enhance a product, making it stronger, or contribute to the product’s failure. Surveillance and monitoring of residual stress is an important element of Process and Quality Control in all industries
Principle of operation:
The PSV-100 is a rugged, portable strain viewer for polariscopic examination of transparent or translucent products, revealing strains and stresses due to manufacturing processes.
Features:
The procedure is non-destructive and can be used on flat and curved samples
Technical characteristics:
exists either with linear or circular polarised filters.
