Parameters
Elastic modulus (E, Young’s modulus), the unit (e.g. N/mm²)
determines the unit of the output signals
Poisson’s ratio (ν, greek nu)
- Strain gauge type. Either 0/45/90° or 0/60/120°
Default
strain gages A, B, C, T: Constant 0.0
E = 200,000 N/mm²
Poisson
’
s ratio ν = 0.3
- Strain gauge 0/45/90°
Exception handling
If one or a number of inputs is marked as invalid (Invalid bit),
the outputs are also marked as invalid. The calculation is
nonetheless done and output.
