Transverse and Diametral Extensometers

Designed for general purpose transverse or diametral strain measurement on axially loaded specimens. This model may be used simultaneously with the Model 3542 axial extensometer.

Specimen Size: Up to 25 mm width or diameter
Measuring Ranges: ±0.5 mm to ±5.0 mm
Temperature Range: -270 °C to 200 °C with -LHT option
Key Features: Durability, easy mounting

A miniature extensometer designed for general purpose transverse or diametral strain measurements on small or thin specimens. May be used simultaneously with the Model 3442 miniature axial extensometers or the Model 3542 axial extensometers.

Specimen Size: Up to 25 mm width or diameter
Measuring Ranges: ±0.25 mm to ±1.25 mm
Temperature Range: -270 °C to 200 °C with -LHT option
Key Features: Low profile, durability, light weight

A single integral unit provides simultaneous, averaged lateral (transverse) strain and averaged axial strain measurement.

Gauge Lengths: 10 – 50 mm
Specimen Size: Up to 50 mm width or diameter with optional adapters
Measuring Ranges: ±5% and ±10% axial; ±1.0 mm transverse
Temperature Range: -270 °C to 200 °C with -LHT option
Key Features: Axial-transverse biaxial extensometer measures Poisson’s ratio with average of two measurements

Designed for transverse or diametral strain measurement in environmental chambers where the entire extensometer must be exposed to elevated temperatures. These capacitive extensometers may be used up to 700 °C (1300 °F) without any cooling.

Specimen Size: Up to 25 mm width or diameter
Measuring Ranges: ±1.2 mm to ±2.5 mm
Temperature Range: Ambient to 700 °C
Key Features: Uncooled transverse extensometer for environmental chambers
