一、概述某些工厂从国外进口的扭力扳手检定仪都是全机械式的,精度低于±2.0%(满量程)、功能少、采用英制计量单位。达到规定的扭矩值时,指示值只维持片刻便下降,靠操作人员跟踪读数,人为误差大。这些仪器已不能满足生产上的需要。我们试制成功的单片机扭力扳手检定仪,利用单 First, an overview Some factories imported from abroad Torque Wrench tester are all mechanical, accuracy of less than ± 2.0% (full scale), less functional, using British units of measurement. When it reaches the specified torque value, the indication value will only decrease for a moment, and the operator will track the readings to make the human error be large. These instruments have been unable to meet the production needs. Our successful trial of single-chip torque wrench tester, the use of single
