industrial SoundSensor

Microphone

Now (Nov 18) available: industrial microphone for heavy-duty industrial applications.

The microphone comes with no pre-amplifier and needs biasing 2-10V DC from 2,2kΩ source. Pre-amplifiers can be customized (A- or C- characteristic)

Part	Description	Unit	Value
housing	material		brass chrome-plated
	Length	[mm]	71
	Diameter	[mm] ø	12,7
acoustic vent	GAW 334 ®GORE	IP	67
	vent loss	[dB] 1kHz 100 Hz	<1 <2
microphone capsule	Diameter	[mm] ø	6
	type	electret condenser
	sensitivity	[dB] f = 1kHz, 1Pa 0dB = 1V / Pa	54 ± 3
	frequency	[Hz]	10 - 10000
	SNR	[dBA] f = 1kHz, 1Pa A-weighted	56
	operating voltage	[V]	2 - 10V
	output impedance	[kΩ]	2,2
	temperature	[°C]	-20 +70

Next, we will develop a SoundSensor solution based on the microphone and an industrial codec.

industrial codec will be cable-bound and heavy duty.

In terms of protocol we are still investigating. I-O LINK is number one, currently.
