Miniature Axial Extensometers Series 3442
Gauge lengths are available from 3 mm to 50 mm and full-scale measuring ranges from ±0.5 mm to +12.5 mm.
Model 3442 extensometers are strain gaged devices, making them compatible with any electronics designed for strain gaged transducers.
Features
-
May be left on through specimen failure
-
All standard units meet existing ISO 9513, class 0,5 and ASTM class B-1 requirements for gauge lengths ≥6 mm and class 1 according to ISO 9513 and ASTM class B-2 for ≤5 mm accuracy.
-
All models can measure in both tension and compression and can be used for cyclic testing.
-
Gauge length pin helps set gauge length accurately for all gauge length configurations.
-
Full bridge, 350 ohm strain gauged design
-
Mechanical overtravel stops in both directions.
-
Rugged, dual flexure design for strength and improved performance. Much stronger than single flexure designs, this also allows cyclic testing at higher frequencies.
-
Gauge length adapter kits enable configuration of multiple gauge lengths with one extensometer.
-
Replaceable arms and spacers for ease of repair.
-
Hardened tool steel knife edges are easily replaced
-
High and low temperature options extend operation from as low as -265 °C to +200 °C
-
Replaceable arms and spacers for ease of repair. This also allows changing the gage length for different test requirements
-
Includes high quality foam lined case
