よくある質問 (FAQ)
-
What is the function / the CON021 converter in this system?
The CON021 converter processes the analog signal from the PR6423 sensor, enabling the signal to be interpreted by monitoring systems. -
Can this sensor be used in high-temperature environments?
Yes, the PR6423/10R-010 sensor is rated up to 180°C and is ideal for hot zones in turbines and compressors. -
Is this sensor suitable for hazardous areas?
Depending on configuration, it can be installed in zones with explosion-pro/ or intrinsically safe requirements, but specific certifications must be verified per model. -
What is the maximum cable length supported between the probe and the converter?
Typically up to 10 meters, with signal quality maintained through coaxial shielding. -
How is this sensor installed on rotating machines?
The sensor is threaded and mounted radially or axially into the machine casing near the shaft surface. -
Does it require calibration after installation?
The sensor is factory-calibrated, but final verification is recommended during commissioning using calibration tools. -
Is this sensor compatible with third-party monitoring systems?
Yes, it outputs a standard voltage signal and is /ten used with Bently Nevada, Emerson, and other API 670 compliant systems. -
What’s the difference between PR6423/10R and other PR6423 variants?
The ’10R’ variant specifies probe diameter, thread type, and calibration; other variants may differ in mounting or application. -
How /ten should the sensor be inspected or maintained?
Typically every 2–3 years during scheduled shutdowns; however, due to non-contact design, wear is minimal. -
Can this sensor detect shaft misalignment?
Yes, it measures both static and dynamic shaft displacement, enabling detection / misalignment and imbalance.
