DT3617 1 Strain Sensor

  • Planar Shear (2) 90 Deg. Gages
  • Self Temperature Compensating
  • Ease of Installation
  • High Output - Two Active Arms

Columbia Series DT 3617 Strain Sensors are designed for the measurements of planar shear strain forces when the axis of principal strain is identified. Each sensor is a complete, compact, easily installed device utilizing the proven technology of the Columbia DTD 2684 Series Fatigue Monitoring Sensors.

The DT 3617 Shear Strain Sensor consists of two 1000 Ohm precision strain gage grids arranged orthogonally on a one mil polyimide substrate and a matching pair of 1000 Ohm bridge completion elements. The entire gage configuration is assembled in a rugged, molded silicone rubber package with four, M22759, 26-gage TFE insulated aircraft lead wires. The bottom surface of the sensor is polyimide substrate of active strain gage elements and is supplied pre-processed for bonding to the test structure. The top surface of the sensor contains the axis identification marking to assist in aligning the gage with the principal strain axis.

Individual models are available to compensate materials commonly used in aircraft structural fabrication. Columbia Model 5802 Strain Gage Amplifier is designed to amplify the sensor signals providing both strain and temperature outputs.
