无限线压力探头提供了一种在困难环境中测量高频波动压力的手段。设计合理的无限线探头不会产生共振；因此，它的频率响应不像传统探头那样受探头管中的声学共振的限制。综述了无限线压力探头的特点，并介绍了其在涡轮发动机研究中的一些应用。描述了一种具有平坦椭圆形截面的探头，允许安装恒定阻抗压力传感器。预测具有圆形和扁平椭圆截面的探针频率响应的技术也被引用。
The infinite line pressure probe provides a means for measuring high frequency fluctuating pressures in difficult environments. A properly designed infinite line probe does not resonate; thus its frequency response is not limited by acoustic resonance in the probe tubing, as in conventional probes. The characteristics of infinite line pressure probes are reviewed and some applications in turbine engine research are described. A probe with a flat-oval cross section, permitting a constant-impedance pressure transducer installation, is described. Techniques for predicting the frequency response of probes with both circular and flat-oval cross sections are also cited.
