Automation for Model 3549 Furnace Extensometers – Model FASTact
Linear automation system for hands-free use of model 3549 extensometers. Enables automatic specimen mounting and retraction. Saves time and simplifies extensometer use.
FASTact enables hands-free testing with Epsilon’s model 3549 high-temperature extensometers. Mounting the extensometer on the specimen and retracting it after the test can be automated two ways:
- Fully automatic when controlled by the testing machine’s software
- Semi-automatic with:
- FAST software – point and click
- FAST handset (optional) – press a button
Operators never have to touch the extensometer or its mounting after the initial setup. FASTact retains all of the model 3549’s features: gauge length is set automatically, optional soak before testing (with the extensometer’s rods near, but not touching the specimen), adjustable contact force, and capability to run in strain control.
FASTact consists of a linear automation actuator, interface electronics, software with a simple command interface, and an optional handset.
- Reduces cycle time.
- Reduces operator training, skill, and experience requirements.
- Fully automated extensometer mounting on the specimen, soak/hold (optional), and retraction after the test when FASTact is integrated using the testing machine’s software (automation options depend on the specific testing machine).
- Semi-automated extensometer mounting, soaking and retraction using FASTact’s included software or the optional handset.
- Never touch the extensometer again after it is set up for the grips and specimen length.
- “Soft landing” feature slows down the actuator just before touching the specimen for the most precise, repeatable extensometer performance.
- Automatically detects specimen contact and stops at a preset contact force (user-selectable).
- Compatible with using the model 3549 extensometer in strain control.
- Programmable settings:
- Contact force
- Mounting speed
- Deceleration speed
- Soak position
Mounting Time: <2 seconds typical; user-selectable in the range of 2 – 8 seconds
Max. Actuator Travel: 250 mm (10 inches)
