Ordering Information
Features
• May be left on through specimen failure.
• 3603 signal conditioner and power supply included. Provides high level DC voltage output with exceptionally low noise (typical 0.1 mV on 10VDC output). Easily interfaced to test controllers, data acquisition boards, and chart recorders.
• Shipped fully calibrated with electronics (traceable to NIST) with user specified voltage output.
• All models can measure in both tension and compression and can be used for cyclic testing.
• Mechanical overtravel stops in both directions.
• All standard units meet existing ASTM class B-1 and ISO 9513, class 0,5 requirements for accuracy.
• Hardened tool steel knife edges are easily replaced. A spare set comes with every extensometer.
• Includes high quality foam lined case and a spare set of knife edges.
• Rugged, dual flexure design for strength and improved performance. Much stronger than single flexure designs, this also allows cyclic testing at higher frequencies.

These extensometers use a high temperature capacitive sensor and do not require any cooling. They will operate up to the maximum temperature limit of most environmental chambers used in materials testing. The Model 3555 is ideal for testing composites, metals and high temperature polymers in tensile, compression or cyclic testing. All units can be displaced in both compression and tension.
The extensometer comes with the Model 3603 signal conditioner. The output is an analog DC voltage, factory calibrated with the extensometer to 0 to 10 VDC typically.
They are readily interfaced with most existing test con­trollers, and may be directly connected to data acquisition systems and chart recorders. Bringing the signal into a spare DC input channel (or external input) on the test controller allows the extensometer to be used for strain controlled tests like low cycle fatigue.
