Bently Nevada 164746-01 Seismic Direct Input Card

Bently Nevada 164746-01 Seismic Direct Input Card

The Bently Nevada 164746-01, also cataloged as the 164746-01 Seismic Direct Input Card, operates as a dedicated hardware component for high-bandwidth data acquisition within Trendmaster platforms. It interfaces directly with case-mounted seismic transducers, such as the 200350 and 200355 piezoelectric accelerometers, executing synchronous and asynchronous signal processing loops to extract vibration variables.

Hardware Specifications

Proximity Transducer Mechanical Monitoring Attributes

The 164746-01 module provides precise electrical conditioning for structural casing acceleration data, converting differential voltage signals generated by raw charge elements. By employing high-resolution 16-bit analog-to-digital converters, the hardware ensures cross-talk suppression between adjacent high-bandwidth lines. This processing matrix handles high-frequency waveforms up to 24 kHz, facilitating real-time analysis of rotor dynamics and mechanical casing stress profiles.

Frequently Asked Questions

Q: What types of processing can be performed simultaneously on this input card?

A: The card executes both synchronous processing (coupled to machine shaft speed) and asynchronous processing (independent of speed variables) across all active channels.

Q: Which transducers are electrically compatible with the 164746-01 interface?

A: The card is engineered to acquire data from 200350 and 200355 general-purpose, hermetically sealed piezoelectric accelerometers.

Field Installation Guidelines

Ensure the parent chassis is isolated from the main supply voltage before inserting the 164746-01 module into its designated backplane slot. Slide the card into the structural guide rails until the edge connector is completely seated, then tighten the front panel fasteners to guarantee proper chassis grounding. Route the differential voltage signal cables from the MIL-C-5015 2-pin accelerometer connectors into the card terminal blocks, maintaining appropriate shielding to prevent electromagnetic noise injection.
