Epsilon Technology Corp. Axial Extensometer Model 3542L

Long gauge length extensometers with gauge lengths greater than 2 inches (50 mm) for tensile and compression testing. These units have been specially designed for long gage length applications where low level strain measurements are required. The dual flexure design makes the 3542L very rugged and insensitive to vibrations. These extensometers are designed for testing a wide range of materials, including metals, plastics, composites and ceramics. Epsilon's Model 3543 is recommended for applications requiring long gauge lengths and larger measuring ranges. The Model 3542L comes standard with Epsilon's quick attach kit, making it easy to mount the extensometer on the test specimen. The quick attach kit can be removed, allowing mounting of the extensometer with springs or rubber bands. The 3542L 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. The signal conditioning electronics for the extensometer is typically included with the test machine controller or may often be added. In this case the extensometer is shipped with the proper connector and wiring to plug directly into the electronics. For systems lacking the required electronics, Epsilon can provide a variety of solutions, allowing the extensometer output to be connected to data acquisition boards, chart recorders or other equipment.
