710A型电子累加计数器(710A Electric Totalizer)
- 用 途：
- 统计计数、机械转数、货币计数、流量计数、组选计数等，被广泛地应用于包装、纺织、机械、印染等行
- 710A型累加电子计数器是我公司在德国亨斯特勒公司的710型累加电子计数器的基础上，针对中国市场最新研制的计数器，它采用高度集成化的贴片元件，占用空间小，计数功能强，可由电压脉冲、接近开关、光电开关、轴编码器或机械触点开关等信号驱动计数，计数频率高。该计数器既可由前面板复位，又可外部电信号复位，使用简便。其内部特有的存储器在掉电或关机后可将计数值保存十年且无需电池。6位红色数码管（LED）显示，清晰度高，易辨识，不易受温度及光线的影响，可用于间断回零的计数工作，如统计计数、机械转数、货币计数、流量计数、组选计数等，被广泛地应用于包装、纺织、机械、印染等行业。

710A type electronic totalizing counter is a kind of new counter which is designed on the basis of the 710 type counter of the German Hyngstler company and is oriented to the chinese market. it used the highly integrated chip components with small space occupation and strong counting function, the counting can be made by the voltage impulse, approaching switch, optoelectric switch, shaft encoder or mechanical electrical contacting switch etc, it has high counting frequency. This counter can be reset by the front panel as well as by the outside electric signals, its use is easy. The unique inside memory will keep the counted value for 10 years after power failure or turning off of the power. The 6-digits-LED display has high resolution and is not easily influenced by temperature and light, it can be used for counting with interrupted reset such as statistic counting, mechanical rotation speed, currency counting, flow counting and group selection counting, it is widely applied in the industries such as packing, textile, machinery and dyeing and printing.
