YXA-150 (YAXC-150) 氨用電接點壓力表采用彈簧管作為測壓敏感元件,主要用于氨氣壓
力的測量。 并通過儀表指針的觸點與設定指針的觸點相接通 (斷開) 控制系統(tǒng)中電路的開關,
以達到自動控制和發(fā)報警信號的目的。
本儀表可與各類膜片隔離器相連接,制成隔膜電接點壓力表,用于測量腐蝕性強、粘度大、
易結晶介質(zhì)的壓力。
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.
