Overview
The MK-R80 is a dual electronic extensometer based on resistance strain gauges for material testing. As it elongates with the specimen, the elastic element deforms and shifts the bonded gauge resistance, and a Wheatstone bridge converts the change into a clean mV output that tracks strain precisely.
Key Features
- Resistance strain-gauge, Wheatstone-bridge design
- Dual extensometer for precise strain capture
- Direct mV output proportional to elongation
- High accuracy (Class 0.5) for precise measurement
- Compact design for straightforward integration
Applications
Mounted on tensile and universal testing machines to measure specimen elongation and strain during material strength testing.
