YXA-150 (YAXC-150) 氨用电接点压力表采用弹簧管作为测压敏感元件，主要用于氨气压
力的测量。 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，
以达到自动控制和发报警信号的目的。
本仪表可与各类膜片隔离器相连接，制成隔膜电接点压力表，用于测量腐蚀性强、粘度大、
易结晶介质的压力。

YXA-150 (YAXC-150) ammonia electric contact pressure gauge ,adopted bourdon as
sensitive element ,especially in the measurement of ammonia pressure. The pointer of
instrument will make contacts turn on or cut with set finger contacts, leading to the cut and
turn-on of control system for the purpose of automatic control and
alarm.
This model can be matched with many kinds of capsule insulators ,crank out diaphragm
electric contact pressure gauge,measuring the pressure of corrosion ,glutinous and crystal-
lographic medium.
