September 30, 2019, Depew, NY – PCB Piezotronics, Inc. released the 079A52 grid cap, which is a cost effective acoustic accessory designed to extend the lifespan of a delicate condenser microphone.

The 079A52 can be used on any IEC 61094-4 working class compliant ½” high sensitivity (50 mV/Pa) microphone. The 079A52 can be ordered as a stand-alone accessory, used with previously owned test and measurement microphones, or can be purchased in a 379A12 or 379A13 microphone kit. Each kit contains a microphone, preamplifier, standard grid cap, rugged grid cap, calibration adapter and correction factors for the effects of the heavy duty grid cap at varying frequencies. The 379A12 kit contains the 378B02 free-field microphone and the 379A13 kit contains a 378C20 random incidence microphone, making them suitable for engine and auto cabin noise tests for the automotive and aerospace industry, consumer goods testing, and environmental and machinery monitoring applications.

Highlights include:

  • Durabilty – extends the life of the delicate measurement microphone
