PCB 426E01 377B02 microphone kit

Product Description

PCB Piezotronics ICP Measurement Kit – Preamplifier & Microphone

This is a complete, ready-to-use acoustic measurement kit from industry leader PCB Piezotronics. It includes a high-quality ICP (Integrated Circuit Piezoelectric) preamplifier paired with a precision free-field microphone, ideal for laboratory and field acoustic testing.

Kit Includes:

1. PCB Model 426E01: 1/2″ ICP Preamplifier

   • Provides signal conditioning and impedance matching.

   • Requires constant current power from a compatible analyzer (typically 2-20 mA @ 18-30 VDC).

2. PCB Model 377B02: 1/2″ Prepolarized Free-Field Microphone

   • Frequency Range: [e.g., 3.15 Hz – 20 kHz typical]

   • Sensitivity: [e.g., 50 mV/Pa typical]

   • Designed for measurements where the sound source is at a distance (free-field conditions).

Applications:

• Sound pressure level (SPL) measurement

• Product noise testing (NVH)

• Environmental and industrial noise monitoring

• Acoustic research and teaching laboratories
