多年来远程压力表的生产是按国外设计力案进行的,在生产和使用上一直存在着严重的质量问题。远程发送压力表(以下简称一次仪表)中,电阻发送器所选用的铂丝电阻材料依赖国外进口价格昂贵。因每次进口的材料质量不一,工艺经常有所变动,影响了产品的性能。远程发送的二次仪表配用的111.12型比率计,是我国现今处于被淘汰阶段的仪表。而这两种仪表的配套方法又很繁杂,它必须在生产时成对配套,配套后不得有任何差错。如有倒换现象,在使用时一次仪表和二次仪表所指示的压力值就会
Over the years the production of remote pressure gauge is designed according to the case of foreign design, production and use there has been a serious quality problems. Send remote pressure gauge (hereinafter referred to as a meter), the resistance of the platinum wire material used in the transmitter depends on foreign imports expensive. Due to the different quality of imported materials, the process often changes, affecting the performance of the product. Remotely sent secondary instrument equipped with 111.12-type ratio meter, is now in our country phase-out instrument. The two instruments supporting methods and very complicated, it must be paired in the production of matching, after matching without any errors. If there is a switching phenomenon, when used in a meter and secondary meter indicated pressure value will be
