The Model HT378B02 1/2-inch (12.7-mm) low-noise, high-temperature acoustic measurement system from PCB Automotive Sensors is a combined condenser microphone and preamplifier system used by test engineers to measure sound amplitude and to perform frequency analysis. The unit can be used at operating temperatures up to 1200°C (2192°F), reducing the need for probe microphones, and is suitable for obtaining accurate measurements in and around a vehicle’s engine, manifold, exhaust pipe, and other hot spots associated with powertrain and the vehicle system’s NVH testing.
