RLG
Product Description
RLG series load monitor has the function of detecting the press load with a strain gauge. It displays the accurate load during press processing, and output stop signals and stops a press machine immediately when abnormality is detected. Multiple detection modes incorporated cannot be ignored when there are eccentric loads for each stroke, and furthermore, load monitoring extends the life of dies, prevents friction and wear of presses, also promotes quality control and rationalization.
