电子计算机用屏蔽电缆本产品技术指标参照IEC189和英国BS53081、用途电子计算机用屏蔽电缆,选用介电常数小的高压聚乙烯绝缘,采用对绞、对屏、总屏(或三线组绞合、组屏蔽、组屏总屏)等结构组成,具有介质损耗小、传输信号能力强、抗干扰性能好特点,能可靠地传输微弱的模拟信号或数字信号,可广泛地应用于发。
例题:温度传感器将采集到的温度值转换为电压信号输入给plc,测量范围是0~100Co,数值经过被CPU集成的模拟量通道0(地址为IW64)转换为0~27648的数字,假设转换后的数字为T,试求以为Co单位的温度值。解:0~100Co的温度值经A/D转换后的数字为0~27648,设转换后得到的数字为T,转换公式为:在编辑指令时,为了保证运算精度,应先乘后除。因为公式中IW64乘以100的运算结果可能会大于16位整数的最大值32767(IW64为16位存储器,模拟值为二进制的补码,最高位为符号位,0为负,1为正),因此应将IW64中的数值数据类型转换为实数再进行乘除运算。

Combined radio frequency cable: 1. Combined coaxial cable is mainly applicable to office buildings and multi-functional zones. Its advantages mainly include repeated wiring and overall project investment cost. 2, combined cable is a new type of cable series, it applies the each unit, all kinds of cable laying project, it has simple structure, flexible configuration, easy installation, novel style, etc. It can not only facilitate engineering design, but also facilitate production and transportation, more convenient installation and construction, is the current cable products. 3. Welcome new and old customers to make customized samples, no matter the size of the batch of our company will be enthusiastic service!
Armored communication cable mechanical protection layer: type 53 adopts 0.15mm thick corrugated steel belt, which is longitudinal wrapped on the basic cable and overlapped on both sides. The surface of the steel belt is coated with plastic to prevent corrosion and water intrusion.
This product is suitable for electronic computers with rated voltage of 500V and cables with high re of anti-interference. Type K B low density polyethylene with anti-oxidation property is adopted for insulation of cable core. Polyethylene high insulation resistance, good resistance to voltage, small dielectric coefficient and temperature and the influence of variable frequency dielectric loss is small, can not only meet the res of transmission performance, and can ensure the service life of the cable. In order to reduce crosstalk and external interference between circuits, the cable adopts shielding structure. The shielding res of cables are respectively adopted according to different situations, such as the method of shielding the hinged combination, the method of shielding the hinged combination, and the method of shielding the hinged combination after the hinged combination. Shielding materials are round copper wire, copper belt, aluminum belt/plastic composite belt three. Shielding pair and shielding pair have good insulation performance. If there is potential difference between shielding pair and shielding pair, the signal transmission will not be affected.
