General description
General description
They provide a very accurate electrical signal, strictly proportional to the strain of the specimen submitted to load application, for determining the Elastic Modulus and strength characteristics as alternative to the Compressometer-Extensometers 55-C0222/F. They can be applied to the specimen surface by a special Adhesive-Catalyst agent and other accessories all included in the 82-P0399/C Strain gauge application kit.
Up to 4 strain gauges ¼ bridge, and up to 8 ½ bridge, can be directly connected by one or two interfaces 82-P0398 to MCC8 and ADVANTEST 9 Control consoles which are suitable for cyclic loading and automatic determination of the Modulus of Elasticity.
Strain gauges can also be connected, by one or two interfaces 82-P0398, to a suitable data logger as, for example, the Datalog 8, 82-P9008. See Datalog, multipurpose data logger.
