Surface microphone is designed for measurement of the true surface pressure, especially in automotive applications.Surface microphone is used for Noise measurement on surfaces including glass and in confined spaces or suited for mounting directly on the car surface during wind-tunnel tests or for easy measurement in confined spaces, for example, on the firewall or the underside of a vehicle. Surface Microphone has a built-in CCLD preamplifier for connection to CCLD inputs.

日本av电影网站Surface microphone is provided with optional mounting pads for easy mounting of the microphone even on the curved surfaces of an automobile. It is is a rugged and stable measurement microphone even its small size.The microphone housing and the metallic parts of the diaphragm-backplate arrangement, including the diaphragm, are all titanium, ensuring uniquely high resistance to corrosion.
