New Precision Array Microphone Family with TEDS for Automotive Testing Applications

June 4, 2008 – Depew, NY, USA - The Automotive Sensors division of PCB Piezotronics (PCB®) has released a new series of acoustic sensors, designed expressly for use in automotive testing applications such as legislative certification; quality control; system & component performance; and vehicle & powertrain NVH, including measurements for powertrain noise; wind noise; road noise; acoustic holography; sound quality; break squeal; and squeak & rattle. These acoustic sensors facilitate the types of precise and reliable sound measurements required of today’s refined cabin interiors, as well as resilience against external inclement weather conditions and harsh underhood environments. All array models include a TEDS-compatible option, allowing for high channel counts and greater traceability, as well as conformance with the IEEE 1451.1 standard.

PCB® array microphones, with integral preamplifier, provide cost-effective multi-channel measurements, and operate from the same constant current source required for ICP® accelerometers, allowing use of PCB® microphones alongside of ICPâ accelerometers in the same test, minimizing set-up time. A full complement of low-noise, ICP® and high temperature preamplifiers and accessories for automotive applications are also available.
