The test of whole steel wire rope to break tension is an important method in examing the overall level of wire rope twisting quality. Along with the requirements of international market and domestic key basic engineering construction to high quality of grade steel rope, the former test to the wire rope down stocks has been not adapting to new requirements.Because the test can not reflect the comprehensive quality level of the wire rope accurately, and the rope breakage tension test gradually become the main measure of the quality assessment wire rope. Wire rope tension tester is an important equipment in measuring force of wire rope breakage.
In the wire rope tension tester system, linear displacement sensor is an important components in measuring deformation of wire rope during the tensile . In the wire rope breakage force test,we not only require displacement sensor can work stably in oil, solution, dust and other heavy conditions, but also require that it has extremely high accuracy in monitoring for its work in a long trip .
Guizhou steel rope company use the MTS company's Temposonics-RP + RH SSI type magnetostrictive displacement transducer, pressure sensor and SIEMENS S7-300 PLC control system as main components in 2000 kN tension machine system they developed .
Because magnetostrictive waveguide tube and activities of magnetostrictive displacement sensor can not contact directly,so it can work normally in bad industrial environment,even in high temperature, high pressure and high electromagnetic interference,it can also work as well. Its output for absolute value and after powering off ,we do not need other treatment to power on again;It is of high accuracy and can be installed easily. The series of Temposionics-RP + RH magnetostrictive displacement sensor is "intelligent" displacement sensor, it has characteristics of high speed, high reliability and high accurate data processing and communication ability, built-in circuit boards contain microprocessor, and USES the...
