CE-series Circumferential extensometer

Description


The circumferential extensometer is designed to directly track average changes in a specimen's circumference as it undergoes compression. Utilizing a high-precision, custom-made roller chain with specialized rollers, the extensometer is securely mounted onto the specimen. Strain gauges are employed to continuously monitor alterations in circumference. As the specimen's diameter expands during the testing phase, the roller chain triggers the extensometer to expand correspondingly. Engineered for self-support, the unit remains in place on the specimen through built-in springs. Various chain lengths can be selected to accommodate specimens of different sizes. The device features a mechanical adjustment function that enables the output to be zeroed out as needed. For added safety, a breakaway mechanism is integrated to protect the extensometer in cases of specimen failure. This model is specifically crafted to fit within testing vessels and is well-suited for operation in high-pressure and high-temperature oil environments. Furthermore, the extensometer is universally compatible with any electronics that are engineered for strain-gauged transducers.
