远传压力表(一般产品均未标型号)是工艺测试和自动控制、保护系统中常用的压力仪表之一。远传压力表属复合式仪表,它的基本结构与一般工业用压力表相同,所不同的只是在其扇形齿轮上附加了一个可变电阻器的动触片。其工作原理(见图)为:当远传压力表的压力部分与压力源相接后,在压力源大小发生变化致使扇形齿轮1产生转动的过程中,同时带动了附加在扇形齿轮上的可变电阻器动触片
Remote pressure gauge (general products are not marked model) is the process test and automatic control, protection system commonly used pressure gauge. Remote pressure gauge is a composite instrument, its basic structure and general industrial pressure gauge the same, the only difference is the fan gear attached to a variable resistor movable contact. Its working principle (see picture) is: When the pressure part of the remote transmission pressure gauge is connected with the pressure source, the change of the size of the pressure source causes the rotation of the sector gear 1, at the same time, the additional gear attached to the sector gear Variable resistor moving contact
