PCB Piezotronics’ New Preamplifier for Acoustic Testing for Space Constrained Applications

PCB Piezotronics’ New Preamplifier for Acoustic Testing for Space Constrained Applications
PCB Piezotronics, Inc. (USA) - PCB Piezotronics Introduces New Design, Ideal for Testing in Confined Spaces.

PCB Piezotronics introduces a new short preamplifier for test engineers and acoustic consultants taking measurements in spaces where traditional microphone systems won't fit or where space constraints are a concern.

This new preamplifier, Model 426A07, converts a high impedance signal from a measurement microphone into a low impedance signal. The preamplifier can be paired with any PCB® ¼" free-field, random incidence (diffuse field) and pressure microphone cartridges to test high frequencies ranging from the human audible range (20 Hz to 20 kHz) up to ultrasonic frequencies (greater than 100 kHz) and high amplitude measurements past the human threshold of pain (up to 194 dB).

Common test applications include space-constrained cavities, impedance tubes, under automotive and jet engines, transmission loss and absorption, and embedded into the walls of cavities and tubes.
