Crack Gauge
Item number: 1-RDS Price on request
Delivery time:Delivery time on request
The three different HBM crack gages can be used to determine the crack propagation on a component. The RDS20 and RDS40 types consist of electrically isolated resistors, i.e. individual circuits are interrupted as the crack progresses. The RDS22 type consists of conductive tracks connected in parallel, which crack when the crack propagates under the crack measuring strip. This gradually increases the electrical resistance of the measuring strip as the crack grows.
