Product Introduction
The Epro PR6424/012-000 is a robust, non-contact eddy current proximity sensor designed to measure shaft displacement, vibration, and axial position in industrial rotating machinery. Developed by EPRO (now under Emerson), this model features a 16 mm diameter probe and is intended for use in conjunction with the CON011 converter, making it a core component of Epro’s machinery condition monitoring and protection systems.
Engineered to perform under extreme conditions, the PR6424/012-000 offers exceptional stability, linear output, and resistance to temperature fluctuations, oil ingress, and electrical noise. The sensor plays a vital role in machinery protection systems compliant with API 670, especially in turbomachinery and heavy-duty rotating equipment. This particular model is factory-calibrated and optimized for applications requiring longer sensing distances and high measurement precision.

Frequently Asked Questions (FAQ)
-
Q: What is the difference between PR6424/012-000 and PR6424/011-100?
A: Both have 16 mm probes, but differ in cable configuration and factory calibration for cable length. -
Q: Does this sensor include a cable?
A: No, PR6424/012-000 is supplied without an integral cable; a separate cable is connected to the CON011 converter. -
Q: Can I use this sensor with a third-party monitoring system?
A: It is optimized for use with EPRO CON011 and MMS systems. Integration with third-party systems may require signal adaptation. -
Q: What is the maximum temperature it can handle?
A: Up to 180°C, depending on accessories such as high-temperature cables and mounting configurations. -
Q: Is this sensor compliant with API 670?
A: Yes, it fully meets API 670 requirements for critical rotating machinery monitoring. -
Q: What types of materials can this sensor measure?
A: It is designed to measure displacement from ferromagnetic materials like steel (e.g., AISI 4140). -
Q: Is the sensor tip oil-resistant?
A: Yes, the sensor is sealed and rated IP65 at the tip, making it resistant to oil and moisture when properly installed. -
Q: What happens if I exceed the sensing range?
A: Exceeding the range can lead to inaccurate readings or signal clipping. Always install within the specified gap. -
Q: Can the sensor be used in underwater applications?
A: No, it is not rated for continuous submersion. Use with sealed housings or enclosures for such environments. -
Q: Is recalibration needed after installation?
A: No, the sensor is factory-calibrated. However, system calibration is recommended if components are replaced or relocated.
