KV series gauges are bonded to areas of a structure or material where cracks exist or are expected to occur. They measure both the propagation length and rate of cracks.

Unlike conventional strain gauges, the grid of a KV series gauge is intentionally designed to be severed by crack formation, causing a change in resistance.

Models:

• KV-5C: Approx. 1 Ω, Base size: 30 × 5 mm

• KV-25B: Approx. 1 Ω, Base size: 42 × 32 mm
