Eddy-Current Probe Scaling and Gap Signal Processing

The Bently Nevada 170180-01-05 processes proximity and accelerometer signals through two independent input channels. Therefore, each channel maintains separate signal conditioning paths for connected transducers.

The module supports -24 VDC Proximitor operation and allows FieldMonitor systems to acquire vibration and displacement-related signals. In addition, eddy-current probe scaling functions maintain the relationship between probe output voltage and mechanical shaft position measurements.

For proximity measurement applications, gap voltage validation uses the typical Bently Nevada -10 VDC target reference for probe operating condition verification. The module architecture supports accurate rotor dynamics monitoring by preserving vibration waveform characteristics and reducing signal interference between measurement channels.

Frequently Asked Questions

Q: How many transducer inputs can the Bently Nevada 170180-01-05 accept?
A: The module provides two independent input channels and accepts up to two transducer inputs through Channel A and Channel B.

Q: Can the 170180-01-05 support both Proximitor and accelerometer inputs?
A: Yes. Each channel supports -24 VDC Proximitor or accelerometer signal inputs according to the configured measurement application.

Q: Does the module require a dedicated FieldMonitor Terminal Base position?
A: Yes. The 170180-01-05 occupies one slot within a FieldMonitor Terminal Base for mechanical installation and electrical connection.

Field Installation Guidelines

• Install the module only in a compatible FieldMonitor Terminal Base slot.
• Verify channel configuration before connecting field transducers.
• Use shielded instrumentation wiring for vibration and displacement signal connections.
• Connect cable shields according to site grounding practices to reduce electrical noise.
• Separate transducer signal wiring from high-current power cables and switching circuits.
• Confirm Proximitor supply polarity before energizing the module.
• Check sensor wiring continuity and insulation resistance before system startup.
• Verify gap voltage readings after installation to confirm correct probe positioning.
