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.
-
TYPE 4948-B
Aerospace Surface Microphone
Surface Microphone Type 4948-B is designed for measuring airplane surfaces during in-flight testing. The microphone also well suited to wind-tunnel testing, limited spaces, or near to hard reflective surfaces, and is supplied with two coaxial cables and CIC.
-
TYPE 4949
Surface Microphone For Automotive Applications
Automotive surface microphone designed for measurement of the true surface pressure. Ideal for mounting directly on the car surface during wind-tunnel tests and for measuring in confined spaces.
-
TYPE 4949-B
Automotive Surface Microphone
Automotive Surface Microphone with two coaxial cables and CIC, designed for measurement of the true surface pressure, especially in automotive applications. It is well-suited for mounting directly on the car surface during wind-tunnel tests or for easy measurement in confined spaces.
-
TYPE 4952
Outdoor Microphone For Long-term exterior use
Outdoor Microphone Type 4952 provides class 1 compliant outdoor sound measurement in compliance with IEC 61672. The microphone is built from polymer materials, protecting the microphone from changing weather in longer periods of outdoor use.
