Deflection gage 3540 series

Widely used for measuring deformations in three- and four-point bend tests, compression tests and a variety of general-purpose deflection measurements. These strain gaged devices come with a magnetic base for easy mounting. Deflection is measured with a single arm with an attached spherical contact tip, similar to those on a dial indicator. The full bridge strain gaged construction provides an electrical output compatible with any electronics designed for a strain gaged transducer. The magnetic base furnished with the gage can be mounted to the desired reference surface, whether flat or round. The tip can then be positioned to measure the deformation encountered during the test. These units come standard with the arm set to measure downward deflections when oriented in the upright position. They can be used upside down or in any orientation. Operation of these extensometers are verified to either ASTM E2309 or ISO 9513 standards using in-house calibration systems that are calibrated with Epsilon’s traceable laser interferometer system.
