两线制变送器因为信号起点电流为4mA.DC，为变送器供给了静态作业电流，一起外表电气零点为4mA.DC，不与机械零点重合，这种“活零点”有利于辨认断电和断线等毛病。并且两线制还便于运用安全栅,利于安全防爆。两线制变送器如图一所示，其供电为24V.DC，输出信号为4-20mA.DC，负载电阻为250Ω，24V电源的负线电位低，它即是信号公共线，关于智能变送器还可在4-20mA.DC信号上加载HART协议的FSK键控信号。

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.
