PCB Automotive Sensors claims that its Model HT378B02 ½-in. ICP low-noise, high-temperature acoustic measurement system is the world’s first IEC-compliant microphone and preamplifier system used to measure sound amplitude—in Pascals or decibels—and to perform frequency analysis. What’s more, test engineers can use the device at operating temperatures of up to 120°C, reducing the need for high-priced probe microphones.
The Model HT378B02 is well-suited for obtaining accurate measurements in and around a vehicle’s engine, manifold, under the hood, exhaust pipe, and other hot spots associated with powertrain and vehicle systems NVH (noise, vibration, and harshness) testing.
