High Temperature, 1/2 Inch ICP® Low-Noise Microphone Preamplifier
For Automotive Underhood, Powertrain NVH and Near-field Acoustic Measurements

The industry exclusive Model HT426E01 high temperature, 1/2 inch ICP® low-noise microphone preamplifier from PCB Piezotronics (PCB®) is designed to overcome specific high temperature challenges associated with powertrain and vehicle systems NVH test applications. Model HT426E01 provides an operating temperature range of - 40 to + 120 °C (- 40 to + 248 °F ), as well as a low attenuation factor of -0.06 dB and low electrical noise. This 1/2 inch preamplifier operates from ICP® sensor power, terminating with a BNC connector and utilizing standard coaxial cables.

Model HT426E01 offers minimal set-up and system cost, and eliminates the need for high-priced probe microphones. When this ICP® preamplifier is used in concert with a prepolarized microphone as a measurement system, existing ICP® accelerometer and pressure sensor set-ups may be utilized, minimizing overall testing costs and increasing efficiencies. The model’s TEDS compliant circuitry allows for on-board memory storage and traceability, and is ideal for applications requiring larger channel counts.
