Elastic Limit Detection And Reset Testing System
US Patent:
4480482, Nov 6, 1984
Filed:
Dec 29, 1982
Appl. No.:
6/454323

International Classification:
G01N 310
US Classification:
73805
Abstract:
The signal output of a pressure transducer, measuring the increasing tensile load above a minimum level on a test specimen, is differentiated to produce an analog slope signal compared with an adjusted sensitivity voltage to generate a reset signal when the elastic limit of the specimen is exceeded. Through digital gate logic enabled above a minimum tensile load, the reset signal terminates loading of the specimen to prevent destruction thereof.
