摘　　要：为了克服传统机械开关的可活动部件由于绣蚀、积尘、润滑枯涩、松动、振动、温度膨胀、偏心等原因引起的卡涩,防止保护误动或拒动。提高压力开关可靠性差以及精度(传统机械开关精度一般为4%)。麦普兹成功研发了ME系列两线制无源电子压力开关。麦普兹开关在现场大量的成功应用,彻底解决了机械式开关的可靠性差、精度低的不足,展示了微功耗技术带来的无故障和无漂移的巨大优势,为提高压力开关及仪表的可靠性找到了一条新道路。In order to overcome the traditional mechanical switch can be moving parts due to rust, dust, lubrication Kuse, loose, vibration, thermal expansion and eccentricity caused by unsmooth and prevent the protection misoperation or maloperation. Improve the reliability and accuracy of the pressure switch （traditional mechanical switch accuracy is generally 4%）. MYPTS have successfully developed a series of more ME two wire passive electronic pressure switch. MYPTS hereby switch in the successful application in a lot of, completely solve the poor reliability of the mechanical switch and disadvantages of low precision, showing the micro power technology bring the no fault and drift free huge advantage and find a new way to improve the reliability of the pressure switch and instrument.
