46BL 1/4″ CCP Pressure Standard Microphone Set, High Sensitivity
from GRAS

Microphones and Accelerometers

46BL is ideally suited for production line testing of portable communication devices, such as cell phones, laptop computers, tablets, GPS receivers and similar devices using microspeakers.

It is also well suited for general acoustic measurements when high sensitivity and low noise are required.

Regarding temperature range, see the specifications. Should higher temperature limits be required, we recommend the G.R.A.S. probe microphones, where the microphone and preamplifier can be isolated from the hot source.

Compatibility

To perform as specified, the G.R.A.S. 46BL microphone set requires a constant current input module that can deliver 4 mA and 24 V unloaded CCP voltage supply. If the constant current supply is lower, the capability of driving long cables is reduced and consequently the upper frequency is reduced. If the voltage supply is lower, it will influence the upper dynamic range.

The microphone set is terminated with a 10/32 Microdot female connector. Ready-to-use coax cable assemblies of various types and lengths are available in standard as well as customized lengths.

The 46BL is IEEE 1451.4 TEDS v. 1.0 compliant. If your measurement platform supports Transducer Electronic Data Sheets, you will be able to read and write data like properties and calibration data.
