Eddy-Current Probe Scaling & Gap Voltage Validation
The combination of the 16 mm probe tip and the CON021 signal converter establishes precise eddy-current probe scaling across wide measurement gaps. Field setup requires gap voltage validation (-10 VDC targets) measured across the converter diagnostic terminals to place the shaft target in the center of the probe's linear response curve. Correct installation suppresses signal crosstalk and maintains phase linearity during high-amplitude shaft motion, allowing accurate analysis of complex rotor dynamics.
Frequently Asked Questions
Q: How does the CON021 signal converter derive power for the PR6424/01 passive probe?
A: The CON021 accepts a 24 VDC external power feed, generates an internal high-frequency excitation voltage, and transmits this signal to the passive PR6424/01 probe tip via the coaxial cable interface.
Q: Can the CON021 converter operate with non-matched total cable lengths?
A: No. The internal oscillator and linearization circuits in the CON021 require a specific total system length (such as 5.0 m). Deviations in total cable length alter system capacitance and compromise linear output calibration.
Q: What mounting configuration is required for the CON021 converter in field cabinets?
A: The CON021 mounts directly on standard 35 mm DIN-rail systems inside control panels and uses screw terminal blocks for 24 VDC power, raw sensor wiring, and linearized analog output connections.
Field Installation Guidelines
Snap the CON021 signal converter onto a grounded 35 mm DIN-rail inside an enclosure, maintaining adequate terminal clearance for field wiring. Secure the PR6424/01 probe into the bearing housing, adjusting the thread depth until the converter output matches the target DC gap voltage. Route the coaxial extension cabling through dedicated metal conduit to prevent electrical noise interference, and ground all cable shields at a single point on the cabinet earth bus bar.
