High Temperature Preamplifier for Automotive Sensors Operates to +120°C
The Automotive Sensors division of PCB Piezotronics announced a high-temperature preamplifier, designed to overcome high temperature testing challenges associated with NVH powertrain and vehicle underhood testing applications. The Model HT426E01 is a 1/2” 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.
