YJM-2系列车用压力继电器 - 阳雷气动液压（上海）有限公司

　　YJM-2压力继电器所接受的气信号压力较高，它利用气压信号变化来接通或断开电路。它具有结构简单，膜片动作滞后小，回差和动作重复精度高等优点。
YJM-2 pressure relay receives air signal with high pressure, the relay close/opens circuit by means of the changes in the air pressure signals.
The relay features a simplestructure small retardation of membrane action and high repeatability preciston in hysteresis error and ction.
