AEX500 Automatic Extensometer

Long travel automatic gauge length extensometer Application: The extensometer AEX500 is suitable for almost all samples of a gauge length (Le) from 10 mm. Because of its rugged construction and high accuracy the AEX500 nearly meets all applications in measurement of linear strain (determination of the E-modulus up to sample fracture). It works without restrictions in both the upper as well as the lower test area. Design and function: The AEX500 has a smooth running and nearly frictionless linear guidance of the measuring heads. Due to the non-contact incremental gauge the AEX meets all requirements of class 0.5 (EN ISO 9513) over the whole travel. The measuring heads may easily and quickly be removed from the device by unlocking two screws with pin guidance. Compatible with Tinius Olsen ST and SL series of materials testing systems

Accuracy class 0.5 (EN ISO 9513) Resolution max. 0.01μm (1 Vpp) or 0.05μm (RS422/TTL) Gauge length from 10 mm Automatic movement to the position and initial gauge length Automatic attachment to the specimen Measuring travel 500mm minus gauge length Operating range in upper and lower testing space possible

Accuracy class EN ISO 9513: 0.5 Indication error (rel.)*: 0.5% Indication error*: 1.5μm Error in gauge length (Le): ± 0.5% Gauge length (Le): 10 to 500mm minus travel Activating force: max. 0.01 N Clamping force: .5-1 N Operating temperature range: 0-50°C Weight: approx. 30kg
