- Frequency Response: 0 Hz to 5500 Hz ± 1 dB, capturing dynamic pressure changes in rotating machinery.
- Linearity, Hysteresis, Repeatability: ≤ ±0.3% FS, delivering high measurement fidelity.
- Proof Pressure: 1.5X full scale; Burst Pressure: 3X full scale (2X FS on 689 bar/10,000 psia units), providing safety margins.
- Materials: Gold plated per MIL-G-45204 Type III Grade A, C-276 welded to 316L stainless steel body, ensuring corrosion resistance.
- Environmental: Designed to meet IP67; humidity 95% condensing; pollution degree 2; maximum use altitude 2000 meters.
- Compliance: FCC Part 15, EMC EN 61326-1, RoHS 2011/65/EU, ATEX EN 60079 series, and cNRTLus certifications for hazardous locations.
Industry Applications
This cable excels in applications requiring precise cylinder pressure monitoring:
- Compressor Performance Monitoring: In natural gas or petrochemical plants, the 146824-0050 provides real-time pressure data to optimize compressor efficiency and detect faults early.
- Engine Testing: For diesel or gas engine development, its wide frequency response (0–5500 Hz) captures combustion pressure variations, aiding in tuning and validation.
- Hydraulic Systems: In heavy machinery, the robust construction and IP67 rating withstand oil mist and vibration, ensuring reliable pressure readings.
Installation & Setup Guidance
Proper installation ensures optimal performance. Mount the transducer with a torque of 68 N-m (50 lbf-ft). Use compatible O-ring materials: Hifluor (black) for hydrogen sulfide, sulfuric acid, butane, fuel oil, petroleum oil, turbine oil, propane, propylene, butylenes, and natural gas; Ethylene Propylene (purple) for ammonium hydroxide and anhydrous ammonia. Route the 50 ft cable away from high-voltage lines to avoid electromagnetic interference. Verify the power supply is within 18–30 Vdc before connection.
Maintenance & Reliability
Regular inspection of the cable and connector for wear or damage is recommended. The gold-plated contacts resist corrosion, but periodic cleaning with a dry cloth (no solvents) maintains signal integrity. The sensor head operates at up to 150°C (302°F), while the electronics housing is rated to 85°C (185°F). The O-rings should be checked for compatibility with the process media to prevent leaks. This cable's robust design minimizes downtime, offering long-term value.
Compatibility & Integration
The 146824-0050 integrates with Bently Nevada monitoring systems and third-party data acquisition equipment that accept 0–10 Vdc analog inputs. Its 50 ft length allows flexible placement of transducers away from controllers. The ATEX and cNRTLus certifications ensure safe use in hazardous areas (Zone 0, Zone 2, Class I, Division 1 & 2). No special software is required; the cable is a passive component.
Selection Guide & Purchasing Advice
Before ordering, verify the required pressure range and cable length. The 146824-0050 offers a 50 ft (15.2 m) cable; other lengths are available with different part numbers.
