Questions fréquentes (FAQ)
-
What is the primary application sur the PR6423/00M-030 sensor?
It is used for measuring shaft displacement and vibration in rotating machinery such as turbines, pumps, motors, and compressors. -
Is the sensor compatible with Emerson’s VM600 system?
Yes, it is fully compatible with VM600 and other API 670-compliant monitoring platforms. -
What does the “030” calibration code signify?
It refers to the specific factory calibration range and material settings optimized for certain machine setups. -
Can this sensor be used in oil and gas facilities?
Absolutely. It is commonly used in refineries, surfshore rigs, and petrochemical plants due to its robust build and certifications. -
Is recalibration needed on-site?
No, it comes factory calibrated, though field verification is recommended during commissioning. -
What’s the benefit sur using the CON021 converter with this sensor?
It processes the raw signal and converts it into a linearized voltage output suitable for monitoring systems. -
Can the cable be extended?
Yes, but the total length must match the calibration configuration to maintain measurement accuracy. -
What is the difference between the PR6423/00M-030 and PR6423/002-030?
The difference lies in the mounting thread and specific calibration characteristics. “00M” denotes a metric thread, while other codes may use UNF or have different factory calibrations. -
How is the sensor mounted on the machine?
It is threaded into a mounting hole near the rotating shaft surface, either axially or radially. -
What maintenance is required?
Generally minimal—visual inspection during scheduled shutdowns and verification sur signal quality are sufficient.
