Which installed hardware must be paired with CON021?

Use CON021 with the documented PR642x eddy-current transducer system components: Matched PR642x or PR6453 probe, Compatible extension cable where specified, Negative DC instrument supply.

How should the Converter model value for CON021 be verified?

Confirm the complete nameplate and order code before work; the documented converter model is CON021.

What connection detail is critical when installing CON021?

Preserve every conductor, connector and shield identity, then follow the model-specific connection arrangement described in the controlling Emerson document.

What configuration record should be retained when replacing CON021?

Retain the as-found position, alternative model, cable or channel identity, gap or scaling value, diagnostics and final functional-test result.

Can CON021 replace a similar Emerson model without engineering review?

No direct substitution should be assumed; verify the full order code, measuring function, interface, cable or channel arrangement and the approved PR642x eddy-current transducer system configuration.

Information

Overview Manuals Common Applications Product Precautions

Emerson CON021 is pr642x eddy-current sensor signal converter. It supplies and conditions a compatible PR642x probe and delivers the configured proportional voltage signal to the monitoring system.

Interfaces six documented PR642x/PR6453 sensor families
Passes dynamic shaft motion through a 20 kHz bandwidth
Uses a self-locking LEMO probe connection
Provides a voltage output for the connected monitor channel

CON021 operates with Matched PR642x or PR6453 probe, Compatible extension cable where specified, Negative DC instrument supply, Voltage-input machinery monitor.

Engineered applications include Radial shaft-vibration loops, Axial position measurement, Machine centerline observation, Eccentricity and expansion monitoring.

Important Notice: Mount the converter with four M5 fasteners, verify the PR642x family and output range, isolate the negative DC supply, and prove gap voltage plus dynamic response before enabling alarms.

Radial shaft-vibration loops

Conditions probe motion for vibration trending and protection.

Axial position measurement

Converts thrust-position displacement into a monitor-ready voltage.

Machine centerline observation

Maintains a stable non-contact reference for slow shaft-position changes.

Eccentricity and expansion monitoring

Supports low-frequency mechanical movement measurements with the matched probe.

Read the applicable Emerson machinery-monitoring instructions before work. Verify CON021 and the installed PR642x eddy-current transducer system configuration.

Confirm the complete CON021/SNG-CON021 identification and the paired PR642x probe type before removal.

Place the monitored machine and protection channel in the approved maintenance state.

Isolate the negative DC supply and record supply polarity plus output conductors.

Protect the self-locking LEMO interface from dirt, moisture and bent contacts.

Mount the replacement with four M5 fasteners on a stable grounded panel.

Verify the selected -4 to -20 V or -2 to -18 V output arrangement against the monitor input.

Set the probe gap in the approved linear region and check the quiescent output.

Prove dynamic response, polarity and alarm action before returning the channel to service.
