便携式振动波形数据记录器
Portable Data Recorder for Vibration Waveform
【摘要】 振动数据记录器是不用测量导线,能进行多达16次记录的测振仪器,工作带宽为0~1400HZ时,一次记录最长时间165,带宽为0~350Hz时,为645。每次记录的首末页可以人工设置或自动设置。具有RS-232C串行数字输出,无线电遥控开机,启动记录的同步信号由自控与遥控两种手段提供。在多次测量的空闲时间里,自动断电,保留信息存在外部SRAM里。全CMOS器件,蓄电池供电。
【Abstract】 The data recorder is a vibration measuring instrument which may be used to measure dynamic vibration up to 16 records by using no measuring wires. For the bandwid’ h of0~1400Hi, the max. duration of one record is 16s, for bandwidth of 0~350Hi, that is 64s.The beginning and end pages of one record can be set both automatically and manually. Therecorder can be turned on by remote control and enabled to recording by synchronous signalprovided by self-operated control and/or remote control. At idle time of multiple measurements, recorder turns off itself, the preserved information must be stored in external RAM.The recorder contains all CMOS IC. with storage battery supply.
