Portable Impedance Meter System Type 9737 delivers state‐of‐the‐art normal incidence impedance measurements for the aerospace industry.
TYPE 9737
Portable Impedance Meter System Type 9737 makes fast measurements of the acoustic properties of materials without having to remove a material sample.
The impedance meter consists of an easy-to-use hand-held instrument, a LAN-XI data acquisition front end, and PC software. Because it can measure objects in situ, it is ideal for verification after installation of acoustic treatments, and for quality control after all manufacturing processes are complete.
The instrument has a sound source activation switch and status indicator integrated in the handle. An automated pass/fail routine allows production line operators to simply hold the instrument in contact with the in situ test article, and then receive a clear go/no go signal from an LED.
Measurements are also viewable on a PC in real-time for ease of monitoring. The PC software has dedicated routines for measuring key quality control parameters.
The kit consists of a hand-held impedance tube which contains two microphones, a sound source, and integrated sensors to measure temperature, pressure and relative humidity. This is connected to a single front-end unit consisting of a LAN-XI generator module and power amplifier, which is conveniently housed in a double LAN-XI casing.
The flat flange is designed for optimal sealing, and is removable so you can replace it with custom-built curved flanges, for maximal sealing to contoured panels such as fully bonded panels in aircraft acoustic liners, in their final condition.
Results are directly exportable to Microsoft® Excel® and/or Microsoft® Word.
