一种灵敏度高、控制准确可靠、使用维修方便的FQSD-250微机步幅控制仪,由江苏省无线电科学研究所研制成功。该控制仪通过单片微机对光电检测器件光电头和光电开关转入信号的采样分析及对电磁阀油泵液压系统的控制,实施快速、准确地调节制袋长度,具有可双色变换、跟踪方式选择、自动计数、报警等功能。该机与FQSD-250底封机配套,可制作各种不同类型塑料薄膜袋封切,也可与其他需要步幅控制的设备配用。该仪主要技术指标:计数范围 0～9999;最高控制频率 180次/分;电源交流220V±10％。
A high sensitivity, accurate and reliable control, easy to use maintenance FQSD-250 PCP controller, developed by the Jiangsu Provincial Institute of Radio Science successfully. The controller through a single-chip microcomputer photoelectric detection device photoelectric head and photoelectric switch into the signal sampling and analysis of electromagnetic valve hydraulic system control, the implementation of rapid and accurate regulation of bag length, with two-color conversion, tracking options , Automatic counting, alarm and other functions. The machine and FQSD-250 at the end of matching machine, can produce a variety of different types of plastic film bag sealing, but also with other need to control the pace of the equipment used. The instrument main technical indicators: counting range 0 ~ 9999; the maximum control frequency of 180 times / min; power AC 220V ± 10%.
