- Confirm the internal-converter /022-000 order code
- Match trigger settings to the actual sensor and target
- Prove analog and relay outputs before returning the machine to service
Emerson A3311/022-000 is a compact speed and key monitor with internal eddy-current converters for small rotating-machinery installations.
It provides software-configurable speed or phase processing, buffered and isolated analog outputs, and five relay outputs in a wall-mounted IP65 aluminum housing.
Before replacement, confirm the exact /022-000 internal-converter code, sensor and target geometry, trigger behavior, output scaling, relay logic, supply, wiring and saved configuration.
Availability, condition, price, and shipping time for A3311/022-000 are confirmed during quotation.

- Use the documented eddy-current sensor and LEMO interface
- Verify target material, key geometry and probe gap
- Check signal amplitude over the complete speed range
- Retain speed and key channel assignments
- Verify 0/4 to 20 mA scaling and buffered-output polarity
- Match all five relay functions and delays to the approved logic
- Inspect trigger stability when readings fail only at low speed
- Check sensor gap and target runout before changing configuration
- Verify power, grounding and relay suppression when resets occur during switching
- Speed monitoring on small turbines and compressors
- Key/phase-reference output for vibration analysis
- Local speed and relay protection on pumps and fans
