Description

The Bently Nevada 350500-00-00-00-01-01, also cataloged as the 350500 Charge Amplifier Module, operates as a dedicated hardware component for piezoelectric signal conditioning and dynamic pressure measurement within Bently Nevada monitoring platforms.

Hardware Specifications

Transducer Signal Conditioning & Rotor Dynamics

The 350500-00-00-00-01-01 converts high-impedance charge signals from piezoelectric dynamic pressure sensors into low-impedance voltage signals suitable for direct continuous processing. Internal conditioning circuits maintain accurate eddy-current probe scaling integration and perform continuous gap voltage validation (-10 VDC targets) across connected measurement channels. Filtering stages provide active cross-talk suppression between adjacent sensor circuits, preserving signal integrity for rotor dynamics analysis and acoustic pulsation tracking.

Frequently Asked Questions

Q: What physical connector and mounting configuration does the 350500-00-00-00-01-01 utilize?

A: The module features a LEMO input connector and includes integrated mounting hardware designed for standard 35 mm DIN rail installation.

Q: How does the 350500-00-00-00-01-01 scale high-impedance input signals?

A: The module conditions input signals at a factory-set sensitivity of 16 pC/psi (232 pC/bar) and outputs a scaled voltage signal at 100 mV/psi (1.45 V/bar).

Field Installation Guidelines

• Mount the 350500-00-00-00-01-01 securely onto a standard 35 mm DIN rail inside a protective field enclosure.
• Connect the sensor coaxial lead to the LEMO input receptacle, taking care to keep the connector dry and free of surface contamination.
• Connect the cable shield directly to the dedicated chassis grounding lug to prevent electromagnetic noise from distorting low-amplitude dynamic signals.
• Route field signal cables through dedicated grounded conduit, maintaining distance from high-voltage AC cables to avoid inductive coupling.
