为适应国内精密机械测量的需要,机械工业部北京机床研究所和泰兴机床测试仪器厂联合研制成功DWY3型振动——位移测量仪。机械工业部、江苏省机械厅委托扬州地区机械局于一九八二年十二月八同至十日对该仪器进行了技术鉴定。来自研究所,高等院校,机械制造行业的三十多位专家一致认为,这种电容差频调频原理的非接触式精密测量仪在国内是首创。仪器具有灵敏度高、零点漂移小、精度稳定性好,非线性小,使用操作方便等优点,其主要
In order to meet the needs of precision machinery measurement, the Ministry of Machinery Industry Beijing Institute of Machine Tool and Taixing Machine Tool Testing Instrument Factory successfully developed DWY3 vibration - displacement measuring instrument. The Ministry of Machinery Industry and Machinery Department of Jiangsu Province commissioned the Machinery Bureau of Yangzhou District to carry out the technical appraisal of the instrument from December 8 to December 10, More than 30 experts from institutes, institutions of higher learning and machinery manufacturing industry all agree that this non-contact precision measuring instrument based on capacitive frequency-difference modulation is the first in China. The instrument has the advantages of high sensitivity, zero drift, good precision and stability, small non-linearity, easy operation, etc. Its main
