For mechanical testing instruments, a new non-contacting extensometer with integrated software is said to match or exceed the performance of traditional contacting extensometers. The Advanced Video Extensometer (AVE) from Instron Corp., Norwood, Mass., uses a high-resolution digital camera and real-time image processing to make precise strain measurements on material test samples. Because it is non-contacting, it has no influence on the specimen and eliminates the possibility of damage due to energy release at failure. Having no moving parts, it suffers no mechanical wear that could lead to unreliable results. AVE is available with three fields of view and transverse-strain measurement.
