VR2LZ.1/-CN 差压发讯器差发讯器主要用于管路滤油器，当液压系统工作时，滤油器中的滤芯因截系统中的污染物使滤芯逐渐堵塞，进出口油的压力产生压差（即滤芯压力损失）当压差值增大至发讯器调定值时，发讯器自动发出信号，指示系统操作人员应清洗或更换滤芯，确保系统安全运行。
压差发讯装置的基本作用是液压系统在工作过程中，油液中的杂质微粒被滤油器中滤芯所阻档，从而滤芯逐渐堵塞，产生进出楷卓自动化设备（上海）有限公司经销德国品牌工业备件，德国贺德克HYDAC、穆格MOOG、库伯勒KUBLER、科宝KOBOLD、西门子Siemens、丹佛斯Danffoss、恩格斯豪斯E+H等诸多欧美品牌，国外直接货源，原厂拿货，自主进口报关，保证原装进口，批发操作，价格优惠。
