Columbia Series DT3716 sensors were designed to accurately measure both strain and temperature on straight mounting surfaces. These sensors offer all the accuracy, ruggedness and ease of installation of the flight-qualified Series DTD2684 sensors and also incorporate a DIN standard 1000 ohm platinum RTD which provides accurate temperature measurements at the exact point of sensor mounting. Similar devices have been utilized to monitor potential fatigue damage on aircraft subject to thousands of flight hours, high stress maneuvers and landings. The simplicity and reliability of these sensors also makes them suitable for routine use in the laboratory.

Series DT3716 sensors provide automatic temperature compensation of strain outputs when mounted to a variety of surface materials. Models are available to compensate materials commonly used in aircraft structural fabrication as well as other materials as specified. The sensors incorporate 26 AWG teflon insulated lead wires that simplify electrical connection. Columbia Model 5802 Strain Gage Amplifier is also available to power and signal condition both the strain and temperature outputs of the sensors.
