Configured for absolute bearing housing and structural vibration acquisition in 3500 and 3300 TSI monitoring networks, the Bently Nevada 9200-06-05-05-00 (9200 Velocity Seismoprobe Transducer) provides direct physical/electrical execution. The two-wire moving-coil transducer converts casing velocity into an analog signal for continuous vibration monitoring.

Suffix Breakdown & Model Matrix

Hardware Specifications

Machinery Monitoring and TSI Integration

The 9200 series moving-coil velocity seismoprobe measures dynamic casing displacement and absolute bearing housing velocity with a factory-calibrated sensitivity of 20 mV/mm/s (500 mV/in/s). Dynamic internal damping maintains proportional frequency response across low-speed machinery profiles down to 10 Hz (600 cpm).

During installation, engineers evaluate mounting angle constraints within the permitted 0 deg +/-100 deg envelope to ensure uninhibited internal coil movement during rotor dynamics transitions. Signal wiring practices enforce cross-talk suppression and eliminate ground loop interference across adjacent velocity monitoring channels.

Frequently Asked Questions

Q: Does the 9200-06-05-05-00 seismoprobe require external loop power?

A: No. The transducer uses a self-generating moving-coil design that generates a proportional voltage signal directly from structural vibration.

Q: What orientation limits apply to the 06 mounting angle option?

A: Option 06 allows an operating angle envelope of 0 deg +/-100 deg from true vertical without degrading internal coil travel.

Q: How is the physical wiring connected to the transducer head?

A: Option 05 features a top-mounted terminal block connection for direct two-wire conductor termination.

Field Installation Guidelines

• Thread the integral 1/2-20 UNF-3A stud cleanly into the pre-tapped bearing housing port, applying standard torque to ensure solid mechanical contact.
• Confirm that the transducer mounting orientation stays strictly within the 0 deg +/-100 deg angular threshold.
• Secure the two-wire conductor leads to the top-mount terminal block, applying appropriate wire ferrule terminations to prevent loose strands.
• Route the two-wire shielded cable through grounded metallic conduit, keeping signal lines isolated from high-voltage AC lines.
• Ground the cable shield at the main monitoring rack chassis while leaving the transducer end isolated to prevent ground loops.
