Low Noise Prepolarized Microphone

378A04

PCB Piezotronics, Inc.

378A04 - PCB Piezotronics, Inc.

The 378A04 is a matched system that is comprised of a high sensitivity microphone and a low noise preamplifier that contains a built-in filter that enables the free-field response to remain flat over a wide frequency range. The system requires a minimum of 4 mA and measures to 6.5 dBA (5.5 dBA typical) within a cost efficient, prepolarized (0V) design. PCB's model 378A04, the industry's first prepolarized low noise microphone and preamplifier system allows you to measure extremely low amplitudes. In the past this was only possible with externally polarized solutions. With a typical noise floor of 5.5dBA, this microphone system delivers all of the benefits commonly associated with prepolarized systems.

Dual-Mode Charge Amplifiers

PCB Piezotronics, Inc.

PCB Piezotronics, Inc.

Dual-mode charge amplifiers represent a versatile solution for both piezoelectric charge mode and ICP® sensors. Among the advanced features offered by models 443B01, 443B02 and 2775C are an ultra-low noise floor, sensor fault detection, overload detection, a built-in calibration reference signal, and an RS-232 port for seamless computer control. Notably, model 443B02 features a long discharge time constant selection, ideal for capturing quasi-static events lasting several seconds, a capability particularly beneficial for ballistics and ammunition testing applications. Model 2775C features AC, DC, and servo outputs.
