Abstract:

The transducer discussed in this report is a device that measures strain up to 50 per cent on viscoelastic materials such as the binder used in solid-propellant motors. The transducer is designed for surface mounting although the basic gage concept is also applicable to a device which can be embedded within a material. The active element is a mercury base fluid column of 6-mil diameter and 0.5-inch lengths. Complete information is presented regarding the transducer construction, calibration and evaluation testing.
