BENTLY Nevada 140734-05 Dynamic Pressure Monitoring Module – Continuous Combustion and Pulsation Insight for Critical Rotating Assets

• Warranty: 365 days

• Delivery: 1 week if in stock; no more than one month at the latest

• Payment: 50% advance payment; full payment prior to delivery

• Express options: FedEx, UPS, DHL

• Dynamic pressure channels: Optimized for piezoelectric pressure sensors to capture combustion and pulsation signatures with high bandwidth.

• Real-time alarms (Alert/Danger): Configurable setpoints help you catch instability, surge, or flameout precursors early.

• Buffered dynamic outputs: Front-panel BNC typically provides raw signal access for analyzers or portable recorders.

• Keyphasor correlation (when available): Phase-referenced analysis for order tracking and synchronous investigations.

• Rack integration: Works within the BENTLY Nevada rack ecosystem, leveraging backplane power, alarm relays, and system communications.

• Noise-resistant measurements: Designed for harsh, high-EMI environments found around turbines and compressors.

• Gas turbine combustion dynamics monitoring (DLN/lean-premix stability tracking).

• Reciprocating compressor pulsation detection and anti-surge diagnostics.

• Boiler and furnace acoustic monitoring to spot instability or flame anomalies.

• Hydroacoustic/pipe resonance surveys in high-pressure process lines.

• R&D and test stands needing phase-referenced pressure spectra and trends.

A maintenance engineer at a combined-cycle plant shared that adding dynamic pressure channels reduced nuisance turbine trips by letting them see and correct combustion rumble during load transitions.

• Reliability: Industrial-grade design that typically holds calibration and signal integrity even near hot sections.

• Compatibility: Seamless use with BENTLY racks, Keyphasor references, and existing historian/controls via rack comms.

• Cost-conscious: Early detection of combustion instabilities and pulsations often prevents expensive unplanned outages.

• Data confidence: Buffered outputs for portable analyzers; easy correlation with vibration and process tags.

• Lifecycle support: Spares, configurable alarms, and firmware upgradability help extend system life in many cases.

• Cabinet & environment: Install in a clean, ventilated 19-inch cabinet; maintain ambient 0–65°C, humidity below condensation.

• Wiring: Use shielded, low-noise cables for dynamic pressure sensors; ground shields at the rack end; keep sensor cables away from power lines.

• Sensors: Pair with suitable IEPE or charge-type dynamic pressure transducers; verify mount torque and orientation per OEM sensor guidance.

• Safety: De-energize the rack slot before insertion or removal; follow site LOTO procedures.

• Routine checks: Quarterly inspection of connector tightness, channel bias/health, and sensor drift; clean dust from front panel openings.

• Calibration & firmware: Annual calibration against a reference source is recommended; keep firmware aligned with the rack system monitor for stability.

• CE conformity; typically UL/cUL recognized for system use

• RoHS compliant design

• Manufactured under ISO 9001 quality systems

• Standard warranty: 365 days

From my experience, pairing the 140734-05 with a stable Keyphasor and well-sited dynamic pressure sensors gives the clearest picture of combustion behavior, especially during startup and low-load operation. If you’re consolidating spares, this module seems to be a practical pick for fleets running modern DLN turbines or high-speed reciprocating compressors.
