Product Inquiry

Introduction

Accurate sound pressure acquisition starts with a stable microphone chain. These CCP preamplifiers and microphone sets convert the high-impedance signal from precision microphones into a robust output for professional measurement frontends, supporting laboratory measurements, production quality control, NVH automotive testing, home appliance testing and multichannel acquisition.
 
Integration is straightforward because CCP uses a standardized 2 ÷ 20 mA constant current supply, equivalent to IEPE and CCLD. The two-wire system works with common coaxial cables and BNC connectors, helping users connect microphone sets directly to compatible acquisition systems without complex cabling.
 
The range covers ½" preamplifiers and complete microphone sets with free-field or random-incidence configurations. Individually calibrated microphone sets include sensitivity values and frequency response curves, with sensitivities from 25 to 100 mV/Pa and dynamic ranges down to 16 dBA and up to 140 dBA, depending on the model.

Features

CCP preamplifier principle

The preamplifiers use a constant current powered two-wire system where the signal is superimposed on the supply line.

BNC connection

Preamplifiers and microphone sets use BNC output connectors for connection to professional measurement frontends.

Microphone set configurations

Complete sets combine a CCP preamplifier with a precision ½" microphone in free-field or random-incidence versions.

Preamplifier variants

HDP_CCP variants are available with different gain levels and frequency responses up to 1 ÷ 70k Hz, depending on model.

Individual calibration

Microphone sets are supplied as calibrated units with sensitivity values and frequency response curves for acquisition setup.

Operating range

Preamplifiers operate from -20…+75 °C, with storage temperature from -40…+85 °C.

Microphone compatibility

The preamplifiers are specified for MC21 / MC22E or UC52 microphones, depending on the model.
