PDF《电接点压力表系列》

PD 北京布莱迪仪器仪表有限公司电接点压力表系列 Electric contact pressure gauge series 电接点压力表被广泛应用于石油、 化工、 冶金、 电站等工业部门或机电设备配套中测量 无爆炸危险的各种流体介质的压力.

电接点压力表通常与相应的电气器件(如继电器及接触器)配套使用. 仪表由测量系统、指示装置、电接点组件装置、外壳、调整装置和接线盒(插头座)等 组成. 仪表的工作原理是基于测量系统中的弹簧管在被测介质的压力作用下, 产生位移, 通过 齿轮传动机构将被测值在度盘上指示出来.与此同时,仪表指针带动动触头与设定指针上 的定触头(上限或下限)相接通(或切断) ,致使控制系统中的电路得以断开或接通,以达 到自动控制和发信报警的目的. Electric contacts pressure gauge is widely used to petrochemical, chemical, metallur- gical electric power fields and so forth ,or applied to measurement pressure of fluid medium in the machine. Usually ,electric contact pressure gauge matches with relevant electrical apparatus,for instance,relay and contactor. The instrument is consisted of measurement system,indicating system,electric con- tact parts system, case ,adjustment system,junction box(socket) and otherwise. The principle is that under the conditions of medium pressue ,bourdon tube will show the measured value in the dial by gear wheel equipment . In the meanwhile ,the pointer of instrument will make dynamic contact touch or cut with static one (upper limits or lower limits),leading to the cut and turn-on of control system for the purpose of automatic control and alarm. 目录 PD ・01 -1 型号原型号名称特性索引页 Model Original model Name feature Dage YX;
