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, metallurgical
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 contact
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.

微压膜片电接点压力表BX/BXN
Diaphragm low pressure electric contacts pressure gauge
BX/BXN系列膜片电接点压力表采用膜片作为测压敏感元件，并可根据不同的测量介质选用
不同材料的膜片。本仪表主要用于工业过程中对气体、液体压力微小压力的测量，尤其适用
于腐蚀性粘稠介质（非凝固、非结晶）的微小压力测量，并通过仪表指针的触点与设定指针
的触点相接通（断开）控制系统中电路的开关，以达到自动控制和自动报警功能。
BX/BXN Diaphragm electric contacts pressure gauge adopts diaphragm as sensitive
element, and it could choose different materials baed on different measure mediums. The
pressure gauge mainly applys to measure the micropressure of gas, liquid in industry
course, especially fits to medium of corrosion and viscidity (non-solidification & non-crystal).
The pointer of instrument will make contacts turn on or cut with the contacts of set fingr,
causing the cut and turn-on of control system for the purpose of automatic control and alarm.
