Gap Voltage Validation (-10 VDC targets)
The system utilizes an oscillator circuit to drive the eddy current transducer probe. To ensure accurate linearization over the 2.0 mm measuring range, the system necessitates precise gap voltage validation. The converter centers its output characteristic around a nominal target of -10 VDC, which represents the mid-point of the physical measurement gap. Maintenance of this -10 VDC baseline is mandatory during static commissioning; significant deviations indicate mechanical misalignment, transducer saturation, or degradation of the conductive target surface.
Frequently Asked Questions
Q: Can the CON021 converter be used with different Epro PR642x series probes?
A: The converter is calibrated as part of a matched system. Replacing the transducer probe requires checking the calibration certificate to ensure that the Incremental Scale Factor (ISF) and linearity error specifications remain within system tolerances.
Q: Is the IP66 rating maintained if the cable is cut or spliced during field installation?
A: No. The IP66 rating applies to the factory-sealed sensor head and cable assembly. Any field splicing or modification compromises the environmental integrity of the seal, potentially allowing fluid ingress into the sensor tip.
Field Installation Guidelines
- Mount the sensor in a rigid, vibration-isolated bracket to minimize extraneous mechanical noise and prevent housing fatigue.
- Maintain a minimum shaft diameter of 25 mm for the target area to ensure linear flux density and accurate readings.
- Ensure the initial air gap is set to 0.5 mm using a non-metallic feeler gauge to prevent contact-induced tip damage during operation.
- Route the PTFE-insulated cable through grounded metallic conduit, keeping the lead away from high-current AC power lines to minimize induced electromagnetic interference.
- Inspect all mechanical threads for burrs or contaminants prior to installation to ensure a flush mount against the housing, preventing resonance.
