Product Overview
The Epro PR6424/013-130 + CON021 is an industrial-grade eddy current displacement sensor specifically designed for the non-contact measurement of shaft displacement and vibration in rotating machinery. This system combines the PR6424/013-130 probe, featuring a 16 mm diameter tip, with the CON021 signal converter, which delivers a standard 4–20 mA output for integration into condition monitoring or machine protection systems.
With its robust mechanical construction, high resistance to heat and vibration, and compliance with international monitoring standards such as API 670, the PR6424/013-130+CON021 is ideal for use in steam turbines, compressors, gearboxes, and other dynamic equipment where precise shaft monitoring is critical to performance and safety.

Frequently Asked Questions (FAQ)
-
What differentiates the PR6424/013-130 from the 010-130 model?
The 013-130 variant features specific calibration and configuration for installations requiring slightly longer probe lengths or enhanced mounting flexibility. -
Can the CON021 converter be mounted remotely from the sensor?
No, the converter is factory-paired with the probe and coaxial cable. The complete set must be installed together as supplied. -
Is the sensor suitable for outdoor use or exposed conditions?
Yes, with appropriate sealing and housing, the sensor can withstand wet, dusty, or high-vibration environments. -
Can I use this sensor in a hazardous area (Zone 1 or Zone 2)?
Yes, ATEX-certified versions are available for operation in hazardous areas. Please confirm before ordering. -
What is the response time of the system?
The sensor system supports fast dynamic measurements with a bandwidth up to 10 kHz. -
Does the sensor measure absolute position or vibration?
It measures absolute displacement of the shaft. When connected to monitoring modules, it can derive vibration characteristics as well. -
Can the sensor be reused on another machine after dismounting?
Technically yes, but as the probe is factory-calibrated with the cable and converter, reuse requires care to maintain calibration accuracy. -
Is the sensor field-configurable?
No. It is pre-calibrated at the factory and should not be altered in the field. -
Can the sensor be embedded inside a bearing housing?
Yes. With proper alignment and mounting, it can be embedded directly into bearing brackets or casings. -
Does the system support online condition monitoring platforms?
Absolutely. Its 4–20 mA output can be fed into online CMS systems or SCADA platforms for real-time monitoring.
