Tensile force detecting system of underwater diamond wire saw

A novel dynamic and static tensile force detection system of diamond wire is designed on the basis of the study on the main structure and detection principle of the tensile force sensor of diamond wire. In this system, bridge measurement wiring is composed of foil gauges and signal outputted by sensors is transmitted to the display instrument. This system can accurately and reliably measure and display the tensile force of diamond wire ,which is favorable to improve efficiency of diamond wire saws. Water resistance and resistance to shock of the device are good,which ensure that devices can work safely and stably under water. Actual applications indicate that the structure of the system is simple, and the system can be operated conveniently, in addition measuring accuracy of the system can come to 0. 1% FS and it can be applied to less than 3 000 N. These merits can make the system meet the demands to be used on the spot.
