我厂所使用的电子电位差计,大部份是苏联五十年代的产品,其测量桥路都是干电池供电,这种供电装置十分繁琐,维护和检修都很麻烦,故障率也较多。对这些电子电位差计的测量桥路改用稳压电源不仅可以使仪表内部机构简化,给使用和维护带来方便,同时对保证仪表的精度,提高仪表运行 I use the electronic potentiometer plant, most of the products of the Soviet Union in the fifties, the measurement of the bridge are dry battery-powered, this power supply device is very cumbersome, maintenance and repair are very troublesome, the failure rate is also more. The measurement of these electronic potentiometer switch to the use of regulated power supply bridge not only simplifies the internal structure of the instrument, to facilitate the use and maintenance, and to ensure the accuracy of the instrument to improve instrument operation
