在我国各省级计量部门、各行业归口的计量部门及许多传感器生产企业均建有杠杆式力标准机。确保杠杆平衡和有效施加重力是保证杠杆式力标准机的力值计量性能和提高工作效率的关键。为此,近年出现了变臂比杠杆式力标准机和双杠杆式力标准机或者加载装置,它们无需零点配平,实现了杠杆零点自然平衡。本文针对建立在第一类固定放大比杠杆式基
In our country’s provincial measurement departments, the measurement of the various sectors and many of the sensor manufacturing enterprises have built a lever force standard machine. To ensure that the lever balance and effective application of gravity is to ensure the lever force standard machine force measurement performance and improve work efficiency of the key. For this reason, in recent years, arm-lever-type force standard machines and double lever-type force standard machines or loading devices have emerged, which eliminate the need for zero leveling and achieve a natural balance of the lever zero. This article aims to establish a first class of fixed amplification ratio lever base
