Scope

GB/T 41192-2021 is the English-translated version of 岩土工程仪器振弦式反力计.

GB/T 41192-2021 covers the vibrating wire load cell used as a geotechnical engineering instrument, a sensor that measures the axial pressure on beams, columns and similar members from the change in natural frequency of a vibrating wire.

It describes the product composition, a cylindrical bearing body, a coil, a steel string and a cable, and its main parameters.

It sets the technical requirements for working environment conditions, appearance, pressure performance, water tightness, temperature influence, temperature measurement error, insulation, over-range pressure limit, stability and mechanical environment adaptability, with the matching test methods.

Factory and type inspection rules, marking, the instruction manual, packaging, transport and storage complete it. It applies to the production, sale and inspection of these load cells, was issued on 31 December 2021 and has applied since 1 July 2022.
