Bently Nevada 350500-00-00-00-01-01 Charge Amplifier

Product Overview

The Bently Nevada 350500-00-00-00-01-01 is a specialized Dynamic Pressure Charge Amplifier (DPCA) designed for mission-critical combustion dynamics monitoring in gas turbines. This device acts as a high-precision signal converter, taking the extremely high-impedance charge signal (measured in picocoulombs) from a high-temperature pressure transducer and converting it into a stable, low-impedance voltage signal.

Key Features and Engineering Advantages

• Precision Charge Conversion: Specifically tuned to an input sensitivity of 16 pC/psi, allowing for ultra-sensitive detection of pressure oscillations that could indicate combustion instability or "humming."

• Low-Noise Signal Path: Utilizing high-grade internal shielding and a LEMO connector, the module minimizes the electromagnetic interference (EMI) that often plagues high-impedance signal chains in industrial plants.

• Standardized Voltage Output: By converting the signal to 100 mV/psi, it becomes compatible with standard Bently Nevada 3500/70M dynamic pressure monitors and other data acquisition systems.

• Robust Environmental Design: Engineered to withstand the extreme temperatures and vibration levels found in the vicinity of turbine combustion sections, ensuring a high Mean Time Between Failures (MTBF).

• Simplified Installation: The DIN-rail mount design and compact footprint allow for easy integration into existing instrument junction boxes.
