- Turbine, blower high‑frequency pressure pulsation monitoring
- Oil‑gas, petrochemical plant rotating machinery dynamic pressure protection Performance Parameters:
- Dynamic Pressure Measurement Accuracy: ±1.5% full scale
- High‑speed Sampling Rate: Synchronized with Keyphasor signal Material Composition:
- Front panel: Oxidized aluminum alloy
- Main circuit board: Multi‑layer FR‑4 fire‑retardant PCB with high‑speed sampling circuit
- Internal termination assembly 176449‑05: FR‑4 substrate with gold‑plated screw terminals
- Shield housing: Cold‑rolled steel anti‑vibration anti‑EMI shell
- Backplane bus connector: Gold‑plated industrial connector Structural Characteristics:
- Two‑slot plug‑in main module for 3500 rack
- Front panel LED indicators: OK, Fault, Alarm, Bypass
- Rear‑side mounted internal termination I/O assembly 176449‑05, field transducer cables connect directly to rear internal terminals
- Mechanical locking screws for rack fastening Working Principle: Dynamic pressure transducer signals are directly connected to rear internal termination assembly 176449‑05. High‑speed sampling circuit collects pressure waveform data. Internal processor calculates pressure peak value, pulsation amplitude. Measured values compare with pre‑configured alarm setpoints. When exceeding threshold, alarm signal is sent to rack backplane bus, drives relay module for protection trip, meanwhile upload waveform data to System1 software for equipment failure diagnosisBaker Hugh…. Installation Requirements:
- Install main module with 176449‑05 I/O assembly into two adjacent slots of 3500 rack, power‑off rack before insertion or removal, non‑hot‑swap
- Field dynamic pressure transducer cables connect directly to rear internal termination terminals
- Use Bently Nevada certified dynamic pressure transducer and matched signal cable
- Keep sufficient ventilation clearance for heat dissipation Usage Notes:
- Configure transducer sensitivity and pressure measuring range in 3500 configuration software before commissioning
- Do not arbitrarily change total length of transducer‑cable system
- Inspect rear‑side terminal screw tightness periodically for vibration‑heavy cabinet
- Perform pressure loop calibration in regular maintenance cycle
