Gap Voltage Validation (-10 VDC targets)
The CON021/916-120 converter utilizes a calibrated oscillator circuit to drive the transducer probe. 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 shaft surface. Any deviation from this nominal gap voltage during static conditions indicates potential installation misalignment or transducer degradation, impacting the converter's ability to accurately linearize the output signal.
Frequently Asked Questions
Q: Can the CON021/916-120 be used with standard PR6424 probes or is it limited to the PR6426?
A: The converter is optimized for specific transducer characteristics. Ensure the connected probe's impedance matches the calibration profile of the converter to prevent linearity errors exceeding the specified 1.5%.
Q: Is the IP20 protection class suitable for direct installation on the turbine skid?
A: The IP20 rating requires the converter to be mounted within a protective enclosure or junction box to prevent exposure to moisture, dust, and conductive debris.
Field Installation Guidelines
- Mount the converter housing using four M5x20 screws, ensuring a clean electrical path to the machine ground.
- Utilize the self-locking Lemo-plug for the transducer connection, ensuring it is fully seated to prevent intermittent signal noise.
- Terminate the supply and output wiring using high-quality ferrules for the screw terminals, ensuring the wire gauge does not exceed 1.5 mm².
- Verify the power supply polarity (negative logic) before applying -23 VDC to -32 VDC, as incorrect polarity may result in permanent damage to the internal circuitry.
- Shield all output signal leads and ground the shield at the monitoring system end only to mitigate 50/60 Hz electromagnetic noise.
