PCB Piezotronics, Inc. (PCB®), introduces a new series of miniature, in-line charge converters for use with charge output piezoelectric accelerometers, force and pressure sensors. Series 422E9x has been designed to address the need for lightweight charge converters, which consume a minimal amount of installation space. Units are powered by standard ICP® sensor signal conditioners.

Models 422E91, 422E92 and 422E93 offer standard conversion sensitivities, respectively, of: 0.1 mV/pC, 1.0 mV/pC, and 10 mV/pC, and frequencies from 1.5 Hz to 50 kHz. Units feature 0.25 inch (6.4 mm) diameter stainless steel housings, are 1.6 inches (40 mm) in length, and incorporate 10-32 coaxial input and output connectors. A TEDS option permits channel identification, sensitivity interrogation, and coordinate location information to be stored in an on-board memory circuit, recalled by simple command. These charge converters are ideal for use with charge output sensors engaged in structural testing requirements, aerospace component monitoring, and environmental simulation, where installation space is restricted and mass loading is of concern.
