PS示教式转速仪——一种可为各机械类学生用来测量转速的教学实验用仪器,由同济大学机械系工程机械教研室研制成功,并通过高教局鉴定。该仪器的特色是兼有发电式、磁电式、光电反射式和光电直射式四种测速方式,并有两套数字仪表可进行转速对比,提高了测量精度和分辨率。同时PS便携表还能单独进行实地测量,具有两用性。其内部线路采用大中规模CMOS集成电路,集成度高,整机体积小,布局合理,操作方便,是一种较为理想的教学用转速测量仪器。据悉,国内尚无此类集四种传
PS Teaching Tachometer - A teaching experiment instrument that can be used by various mechanical students to measure speed. It was successfully developed by Tongji University Mechanical Engineering Department and passed the appraisal by the Higher Education Bureau. The instrument is characterized by both generating, magnetic, photoelectric and optical direct-fired four kinds of speed measurement methods, and two sets of digital instruments can speed comparison, improved measurement accuracy and resolution. At the same time PS portable table can also be a separate field measurement, dual-use. Its internal circuits using large and medium-scale CMOS integrated circuits, high integration, small size, reasonable layout, easy to operate, is an ideal teaching speed measurement instruments. It is reported that there is no such set of four kinds of domestic transmission
