Gap Voltage Validation (-10 VDC targets)
The PR6426/010-110 transducer probe, paired with the CON021/916-120 converter, utilizes an oscillator circuit to drive the eddy current field. To ensure linear response across the 12.0 mm extended measuring range, the system requires precise gap voltage validation. The operating range is centered on a target of -10 VDC, which corresponds to the median measurement gap between the sensor face and the conductive target. Any deviation from this nominal gap voltage during static conditions indicates potential installation misalignment or transducer degradation, which directly affects the converter's ability to linearize the output signal.
Frequently Asked Questions
Q: Is the PR6426/010-110 probe interchangeable with other Epro converter models?
A: No. The transducer and converter are calibrated as a matched set. Replacing one without re-calibration of the entire loop will result in significant linearity errors exceeding the specified 1.5%.
Q: Can the converter be installed in a high-vibration zone near the turbine?
A: The converter is rated for 5g vibration at 60 Hz. However, it must be mounted within an IP20-compliant enclosure if the environment contains moisture, conductive dust, or oil mist.
Field Installation Guidelines
- Install the PR6426 transducer probe into a rigid bracket, ensuring at least 15 mm clearance from adjacent metallic surfaces to prevent cross-talk.
- Secure the Lemo-plug connector to the converter, verifying the self-locking mechanism is engaged.
- Terminate the -23 VDC to -32 VDC supply and output wiring using ferrules on the converter's screw terminals.
- Verify correct output polarity (negative logic) before full system activation to prevent internal electronic fault.
- Ground the system shield only at the monitoring system (DCS/TSI) rack to prevent ground loops and high-frequency electrical noise.
