3742 Automatic Gauge Length Extensometers NEW PRODUCT Clip-on extensometers featuring automatic gauge length setting for fast, repeatable mounting to samples — no gauge pins required. Switch gauge lengths in seconds using the new Quick-Swap gauge length system. Built for productivity with high precision. Mounting with 3742’s automatic gauge length mechanism Model 3742 with 25 mm gauge length and +25 mm / -5 mm measuring range The Model 3742 clip-on extensometer is designed for fast mounting and high testing efficiency. It is ideal for laboratories that require frequent specimen and gauge length changes, reduced setup time, and consistent, repeatable strain measurements. The 3742 is applicable for Model 3742 with 50 mm gauge length and testing a wide range of materials, including metals, plastics, +25 mm / -5 mm measuring range composites, and ceramics, in both tension and compression. This model sets the gauge length automatically as the extensometer is mounted on the specimen. Gauge length pins are not required. Gauge lengths can be changed in seconds, without tools, using the 3742’s new Quick Swap gauge length system, and fine adjustments can be made to ensure that the gauge length remains within tolerance. Clamping force is easily adjusted without tools. The Model 3742 includes Epsilon’s quick attach kit as a standard feature, allowing the extensometer to be mounted quickly and easily. Model 3742 extensometers are strain gaged devices, making them compatible with any electronics designed for strain gaged transducers. Most often they are connected to a test machine controller with electronics for a strain channel, and Epsilon will equip the extensometer with a compatible connector wired to plug directly into the controller. For systems lacking the required electronics, Epsilon can provide a variety of solutions for signal conditioning and connection to data acquisition systems or other equipment.
