The MANUFACTURER Bently Nevada 3500/64M is a four-channel dynamic pressure monitor intended primarily for gas-turbine combustor pressure pulsation instability (“humming”). It accepts dynamic-pressure transducer inputs, conditions the signals and compares measured variables with programmable alarm setpoints.
Produces band-passed dynamic-pressure variables with programmable corner frequencies and an additional adjustable notch filter.
Gas-turbine combustion monitoring, instability detection, alarm generation and correlation with operating conditions.
Supports dynamic-pressure sensors through Bently Nevada charge-amplifier arrangements including 350500 or 86517 interfaces.
*MANUFACTURER datasheet hazardous-area entries list T4 at −20 °C to +65 °C when installed according to the applicable drawing; exact I/O and approval configuration must be verified.
Verify the monitor revision, matching I/O module, transducer/charge-amplifier interface, wiring polarity, filter configuration and alarm logic. For hazardous locations, use the I/O/approval option and installation drawing specified for the site. The 3500 documentation set identifies manual 142836 for the 3500/64M; retain configuration records for future lifecycle replacement.
