3. Product Introduction
Machinery protection systems rely on precise displacement signals before a shutdown decision is made. The EPRO CON021 converts the high-frequency eddy-current sensor signal into a usable output for monitoring systems used on turbines, compressors, pumps, and other rotating equipment. It is designed for panel installation rather than direct field mounting (which distinguishes it from some other EPRO converter variants).
The converter works as part of a matched measurement chain with compatible EPRO PR642 series probes. It is not a standalone vibration monitor. Verify sensor compatibility, supply voltage, and output scaling before replacement. Inspect the LEMO sensor connector, screw terminals, and aluminum housing before installation (connector damage can create unstable readings that resemble mechanical faults).

5. Global Compliance & Industry Certifications
Expected regulatory approvals and compliance references for this class of machinery monitoring hardware may include:
- CE Mark for applicable electromagnetic compatibility requirements.
- CSA/North American approvals where applicable to the installed monitoring system.
- ATEX/IECEx certification options when used with approved hazardous-area sensor systems.
- Marine approvals such as DNV GL when installed within certified offshore or vessel machinery monitoring packages.
ATEX/IECEx compliance is especially important for rotating equipment installed in classified areas because the complete sensor circuit must maintain the approved protection concept, including probe, converter, wiring, and barriers.
Verify specific lot certifications with OEM.
6. Long-Term Storage & Asset Preservation Guide
- Store the CON021 in its original anti-static packaging until installation. The LEMO connector and terminal interfaces should remain protected from dust and oxidation.
- Maintain warehouse humidity below 60% RH. Moisture can affect connector contacts and internal electronic assemblies over extended storage periods.
- Inspect stored units every 12-24 months. Check the aluminum housing, mounting holes, terminal screws, and identification labels (asset traceability is critical for machinery protection spare audits).
7. Physical Installation Prerequisites
- Verify the CON021 matches the installed EPRO PR642 sensor type before replacement.
- Install inside a clean, grounded instrument cabinet or enclosure.
- Maintain approximately 50 mm clearance around the module area where cabinet design permits airflow and maintenance access.
- Confirm -24 VDC supply polarity before energizing.
- Use correct shield grounding practices for eddy-current sensor wiring.
- Keep sensor cables separated from high-current motor feeds and variable-frequency drive wiring.
- Verify output scaling and gap voltage during commissioning.
8. Buyer’s FAQ (Logistics & Compliance Focus)
Q: What HS Tariff Code is commonly reviewed for the EPRO CON021?
A: Signal converter modules are commonly evaluated under electrical measuring and control equipment classifications. The final HS code depends on the importing country’s customs interpretation and the declared technical function.
Q: Does Country of Origin (COO) documentation matter for this EPRO spare?
A: Yes. COO records support customs clearance, supplier qualification, and machinery protection asset traceability. Maintain OEM labels, serial information, and receiving inspection records.
Q: Should shipping insurance be purchased for the CON021?
A: Yes. The converter contains precision electronic circuitry and connector interfaces. Use ESD packaging, shock protection, and declared-value insurance for international shipments.
Q: Does the EPRO CON021 include the latest firmware pre-loaded?
A: No. The CON021 is an analog signal conditioning module and does not operate like a programmable controller. Measurement performance depends on compatibility with the connected EPRO sensor, calibration data, and monitoring rack configuration.
