  • Supports displacement, position and machinery-vibration measurement chains.
  • Probe, cable and converter must be treated as a matched system.
CON021 is an Emerson signal converter used with compatible PR642x eddy-current probes to form a machinery displacement measurement chain. It supplies the probe and converts the gap-dependent signal for the monitoring system, so the probe family, cable length, converter execution and channel calibration must remain matched.

Confirm the CON021 execution, compatible probe model, total cable arrangement, power supply, output interface and monitor-channel calibration before replacement. verify supply, converter output, probe gap, linear response, channel scaling and alarm behavior before machine release.

Official source boundary: Use the exact English manufacturer document and installed project record for compatibility decisions.
CON021 technical documentation and verified Moore Automated resources. Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
Confirm the approved PR642x probe, cable components and converter execution as one measurement chain.
Match power, signal polarity, shielding and monitor termination to the cabinet drawing.
Set the reference gap and verify converter output across the required displacement range.

Technical notes

CON021 is controlled by its complete Emerson identity and installed PR642x proximity measurement chain record. Confirm the CON021 execution, compatible probe model, total cable arrangement, power supply, output interface and monitor-channel calibration before replacement. After installation, verify supply, converter output, probe gap, linear response, channel scaling and alarm behavior before machine release.

Converter Chain Identity

Verify the CON021 execution together with the connected probe, cable arrangement, supply and monitoring-channel record.

Conditioned Signal Test

Check supply and grounding, set the approved probe gap and confirm stable converter output and monitor scaling.
