Emerson 9100-00049-03 AMS 6500 Series Shaft Vibration Transmitter

The Emerson 9100-00049-03, also cataloged as the 9100-00049-03 Dual-Channel Shaft Vibration Transmitter, operates as a dedicated hardware component for relative shaft displacement measurement within AMS 6500 Machinery Protection System networks.

Hardware Specifications

4-20 mA HART Loop Protocol and Channel-to-Channel Isolation

The module incorporates two discrete processing paths that provide channel-to-channel isolation to prevent loop noise from corrupting parallel telemetry channels. Raw displacement waveforms from eddy-current probes undergo internal signal conditioning to yield a linear 4-20 mA current loop output proportional to peak-to-peak shaft vibration. Simultaneously, the transmitter isolates and outputs the buffered dynamic AC signal through dedicated terminal interfaces, permitting high-frequency diagnostic connection without risking interruption to the main process control loops or DCS backplanes.

Frequently Asked Questions

Q: Does the 9100-00049-03 transmitter accommodate active hot-swap replacement within an operational AMS 6500 rack?

A: No. Power to the individual slot loop or the dedicated DIN-rail connector must be isolated before decoupling the module to prevent electrical transients from introducing false spikes on the 4-20 mA protective lines.

Q: How are the raw dynamic voltage signals verified for diagnostic cross-checks?

A: The transmitter provides accessible buffered outputs via the terminal connections. Technicians can measure these pins with a calibrated oscilloscope or data analyzer without affecting the primary 4-20 mA signal monitoring loop.

Field Installation Guidelines

• Mount the transmitter securely on standard 35 mm DIN rails or the specified AMS 6500 structural rack chassis.
• Route eddy-current proximity probe extension cables through dedicated, isolated conduits away from high-voltage motor supply wiring.
• Terminate the braided shields of the sensor cables at the designated instrument grounding bar to prevent radio-frequency noise corruption.
• Ensure loop power wiring matches the nominal 24 VDC parameters and is properly fused per API 670 guidelines.
• Maintain clear airflow parameters around the transmitter housing to stay within the -20 to +65 deg C operational temperature limits.
