Measurement Microphone Cartridges
G.R.A.S. Sound & Vibration A/S
Measurement microphones are available in many types covering various frequency ranges, dynamic ranges and application situations. Selecting a microphone involves a number of choices, which can be summarized as:
-
product
Special microphones
G.R.A.S. Sound & Vibration A/S
Special microphones are often required for applications where there are particular requirements regarding the methods of measurements and configurations
-

Power modules
G.R.A.S. Sound & Vibration A/S
It provides polarization voltage for the transducer, ensuring that the microphone gets the charging voltage it needs.It provides supply voltage for the microphone preamplifier. The preamplifier acts as a unity gain impedance converter. It provides a certain amount of line drive capability by providing a low output impedance and output current, making it possible to transmit the signal from the transducer to the Power Module without significant degradation.A power module can provide amplification or attenuation to the signal, thus making it possible to fine tune the measurement chain to the signals being measured and the hardware being used.Selectable filters make it possible to exclude unwanted noise from the measurement, e.g. wind induced noise from outdoor measurements.Overload detection makes it possible to validate the measurements and is a useful tool in monitoring setups.When a Power Module with gain is used, you can use longer cables because of the power module's ability to deliver current.A Power module introduces electrical isolation
