简单介绍： LQ-47系列微形压力传感器采用独特的隔离技术以减小基座的应变敏感效应，是已开发的传感器中最小和最轻的一种。传感器的最大高度不超过0.025英寸，它们可以以过去不可能有的分布密度安装在以前无法触及的叶片的位置上。●为直接安装在叶片表面上而设计；●小尺寸以保持叶片的外形；●高G负载；●低基座应变灵敏度；●高固有频率；●高温工作

LQ-47The range of micro pressure sensors can represent the latest construction standards for a range of sensors designed and developed for installation directly on engine blades. Featuring a unique isolation technology to reduce the strain sensitivity of the base, the LQ-47 series is one of the smallest and lightest sensors ever developed. The maximum height of the sensors does not exceed 0.025 inches, and they can be mounted in previously unreachable positions of blades with a distribution density that was not possible in the past
