嘉兴师范专科学校研制成功 CD-501航道探测仪,它是一种直接显示航道水深的电子仪器。还附有报警装置,当水浅危及船只安全时,会自动发出警告讯号。仪器由集成电路及晶体管混合组成,体积小,重量轻,耗电省,成本低,维修方便。技术指标为:(1)量程:1.1～9.9米;(2)精度:±0.1米;(3)最小测浅深度:不大于1.1米;(4)探测间隔:约3秒/次;(5)超声波频率:48kC;(6)脉冲宽度:0.3～0.5ms;(7)换
Jiaxing Teachers College successfully developed CD-501 channel detector, it is a direct display water depth of electronic equipment. Also attached to the alarm device, when the shallow water endanger the safety of the vessel, it will automatically send a warning signal. Instrument by the integrated circuit and transistor composition, small size, light weight, power consumption, low cost, easy maintenance. Technical indicators: (1) Range: 1.1 ~ 9.9 m; (2) Accuracy: ± 0.1 m; (3) Minimum shallow depth of measurement: not more than 1.1 meters; (4) Detection interval: about 3 seconds / ) Ultrasonic frequency: 48kC; (6) Pulse width: 0.3 ~ 0.5ms; (7) for
