Classification: 27275000 [AHB185003]
| Preferred name | 27-27-50 气动传感器 |
|---|---|
| Definition | 气动传感器是一种依赖于动态压力的技术结构，可以通过喷气压力的变化，在不接触的情况下检测测量物体。气动传感器可分为三种类型：1）气动动态压力传感器（动态喷嘴）；2）气动环形喷射传感器（环形喷嘴）；3）气动空气屏障传感器（空气屏障）。气动传感器通常由以下部分组成：一个气动发送喷嘴/一个气动接收喷嘴/一个气动通路（气隙）/一个气动压力放大器（仅在必要时）和一个电-气转换器 与其他传感器原理相比，气动传感器原理的优点是 ：在污垢积聚、环境温度高、电磁敏感性强的情况下功能可靠/可在完全黑暗的环境中工作/可扫描半透明的测量物体/可在防爆室内工作 |
