ME509 datasheet FLUSH DIAPHRAGM, PIEZORESISTIVE CERAMIC PRESSURE SENSOR

2025-03-19
Metallux ME509压力传感器采用陶瓷基板和冲孔膜片,基于压阻原理设计,专门用于测量非常低的压力。Wheatstone电桥印刷在冲孔陶瓷膜片的一侧,该膜片随后被粘贴到传感器的主体上。电桥面向内部,其中有一个腔室,因此膜片的另一侧可以直接暴露于要测量的介质中。由于直径较大(32.4毫米),因此可以达到更高的灵敏度,从而允许测量低至200毫巴的压力值。由于Al2O3陶瓷优异的化学耐腐蚀性(耐腐蚀性气体、大多数溶剂和酸等),通常不需要额外的保护。Metallux ME509传感器通过激光可调PTC电阻进行热补偿,陶瓷的使用确保在整个测量范围内具有高线性度,将滞后效应降至最低。
