Product Description

Overview

The Bently Nevada 350500-00-00-00-01-01 is a high-precision Dynamic Pressure Charge Amplifier (DPCA) engineered for gas turbine combustion monitoring. It converts high-impedance charge signals from piezoelectric pressure sensors into stable low-impedance voltage signals, ensuring accurate data transmission to Bently Nevada 3500 series monitoring systems. Designed for harsh industrial environments, this amplifier is essential for detecting combustion instability such as "humming" or "rumble," which can lead to serious turbine damage.

Key Features and Technical Specifications

Applications

The 350500 DPCA is primarily deployed in gas turbine combustion systems to monitor pressure fluctuations. By providing early warning of unstable combustion, it protects turbine hot-section components and ensures reliable plant operation.

Installation Notes

For optimal performance, use low-noise interconnect cables between the sensor and amplifier. Standard coaxial cables can produce triboelectric noise, potentially resulting in false pressure readings.

FAQ

Q: Can this DPCA be used with vibration sensors?
A: No, the 350500 is specifically designed for piezoelectric pressure sensors.

Q: What is the operating environment?
A: Suitable for industrial temperatures near turbines; install in slightly protected enclosures for best reliability.

Q: Can it connect directly to the 3500/64 monitor?
A: Yes, it is fully compatible with the 3500/64 series modules.

Q: Are there alternate filter configurations?
A: Yes, the -01 option provides a low-pass setting. Other models may offer high-pass or wider bandwidth configurations.
