Description
GRAS 67TS Turbulence Screen Kit
Introduction
The GRAS 67TS Turbulence Screen Kit is designed for aeroacoustic testing in solid-walled wind tunnels. By attenuating the hydrodynamic component of turbulence up to as much as 25 dB, the acoustic signals of interest can be identified and diagnosed with a much more reliable resolution. The flush-mount turbulence screen integrates the flush-mount and recessed mounting techniques with a special wire mesh into a single unit, and allows for adaptation of several mounting options.The kit does not include a microphone set. The GRAS 67TS-CL-1 includes a GRAS 47BX 1/4" Flush-mount microphone set.
A GRAS 1/4" CCP Flush-mount Microphone Set can be attached to the turbulence screen assembly either with a “rubber band” (O-ring) or a holder plate of POM-material. The parts necessary for both methods are part of the GRAS RA0295 Turbulence Screen Accessories for Flush-mount Microphones. This kit must be ordered separately.
A GRAS 1/4" standard microphone set can be attached to the turbulence screen assembly with a straight or an angled holder plate. These are part of the GRAS RA0296 Turbulence Screen Accessories for standard microphone/preamplifier. This kit must be ordered separately.
As “default” the complete assembly will fit in a flat wall with 4 mm thickness. A hole with diameter 44 mm must be provided. It is possible to attach the assembly using glue. For mounting with screws, the 67TS is provided with 4 holes with diameter 3.1 mm. You are always welcome to contact GRAS for advice or regarding customization.
