PCB Automotive Sensors Debuts High Temperature Preamplifier Operating to +120°C for NVH Powertrain & Vehicle Underhood Testing
March 11, 2008 - Depew, NY, USA - The Automotive Sensors division of PCB Piezotronics (PCB®) has announced release of a new high-temperature preamplifier, designed to overcome high temperature testing challenges associated with NVH powertrain and vehicle underhood testing applications, and to broaden options for NVH test engineers collecting acoustic data in high temperature areas.
Automotive engineers routinely perform NVH tests in areas around the powertrain, where elevated operating temperatures can present major measurement challenges. Underhood temperatures can peak at +125 °C under normal driving conditions, and can be significantly higher near turbochargers and exhaust system components, such as manifolds and diesel particulate filters. In the past, test engineers were limited by preamplifiers offering operating temperature ranges to + 70 °C. Model HT426E01 is a ½" preamplifier operating from ICP® sensor power, terminating with a BNC connector and utilizing standard coaxial cables. The model also features a low attenuation factor (-0.06 dB) and low noise characteristics, 4.9 µV, based on an A-weight scale.
Common automotive applications include underhood measurements for benchmarking and issue identification, including engine radiated, induction, ancillary and turbocharger noise; near-field measurements on manifolds; mufflers; exhaust after treatment components; and tailpipe noise. NVH groups within OEMs and Tier 1 suppliers involved with testing of powertrain components, including engine, engine ancillaries, turbocharger, transmission, intake, and exhaust, will benefit most from this product.
