MODEL DT3617

The Columbia Model DT3617 Strain Sensor is designed for the measurement of planar shear strain forces when the axes of the principal strain are identified. The sensor is a complete. compact, easily installed device utilizing the proven technology of the Columbia DTD-2684 Series of Fatigue Monitoring Sensors. The DT-3617 Shear Strain Sensor consists of two, 1000 ohm precision strain gage grids arranged orthogonally on a one mil polyamide substrate, and a matching pair of 1000 ohm bridge completion elements, The entire gage configuration is assembled in a rugged, molded silicon rubber with four, M22759, 26 AWG TFE insulated Aircraft Lead Wires. The bottom surface of the sensor is the polyamide substrate of the active gage elements, and is supplied pre-processed for bonding to the test fixture. The top surface of the sensor contains the axis identification marking to assist in aligning the gage with the principal strain axes. The Model DT3617 is available in 4 models, dependent on the surface material being tested, Aluminum, Steel, Titanium, and Graphite/ Epoxy.
