Function and Working Principle
The 16925-70 cable acts as a low-noise signal transmission medium in vibration monitoring loops.
Key Functions
- Transfers low-level vibration or velocity signals from field sensors
- Maintains signal integrity over long distances (70 ft)
- Provides strong electromagnetic interference (EMI) shielding
- Ensures accurate data delivery to monitoring systems
- Supports continuous machine protection and diagnostics
Signal Flow
Rotating Equipment → Sensor → Interconnecting Cable → Monitoring Module → Control/Protection System
Role in Industrial Control Systems
The cable functions as:
- A critical link in condition monitoring systems
- A data transmission medium for vibration analysis
- A noise-resistant analog signal carrier
- A support component in predictive maintenance systems
It does not process signals; it only ensures reliable transmission without degradation.
Industrial Applications
The 16925-70 cable is used in:
- Steam turbines
- Gas turbines
- Compressors
- Pumps
- Generators
- Industrial fans
- Petrochemical rotating equipment
- Power generation plants
It is commonly integrated into Bently Nevada 3300 / 3500 monitoring systems.
Installation Guidelines
- Routed through industrial cable trays or conduits
- Connected between sensor and monitoring rack/junction box
- Requires proper grounding of shield to reduce noise
- Must avoid high-voltage or high-EMI cable routing paths
- Installed in fixed machinery monitoring systems
⚠️ Improper routing or grounding can cause signal noise and inaccurate vibration readings.
