TYPE 4948
Aerospace Surface Microphone
Surface Microphone Type 4948 is designed to be used in aerospace. For example, on airplane surfaces during in-flight testing and is also well suited to wind-tunnel testing, limited spaces, or near to hard reflective surfaces.
견적 요청하기Type 4948 is a 1/2" CCLD surface microphone intended for use on airplane surfaces during in-flight testing. The microphone is also well suited to wind-tunnel testing, limited spaces, or near to hard reflective surfaces.
USE SCENARIOS
- Measurement of sound pressure on surfaces
- Acoustic fatigue testing of airplanes
- Wind-tunnel measurements
- Medium- to high-level measurements
- Measurement in confined spaces
The microphone offers high mounting flexibility and its diaphragm is flush with microphone housing in order to minimize the effect of wind-generated noise on the microphone.
