Product Introduction
The Epro PR6424/011-100 is a non-contact eddy current displacement sensor developed by EPRO (now part of Emerson) for high-precision measurement of shaft vibration, axial position, and gap voltage in rotating machinery. Designed for integration with the CON011 converter and compatible with the MMS 6000 and 3000 series monitoring systems, this sensor delivers robust, reliable signal output in even the harshest industrial environments.
With a 16 mm probe diameter, this sensor is particularly well-suited for applications requiring larger linear measurement ranges, offering stable performance under conditions involving high temperatures, mechanical vibrations, and electromagnetic interference. Built to IEC and API 670 standards, the PR6424/011-100 meets stringent requirements in critical process industries such as oil and gas, petrochemical, and power generation.

Frequently Asked Questions (FAQ)
-
Q: What is the difference between PR6424 and PR6423 series sensors?
A: The PR6424 has a larger probe diameter (16 mm) and is optimized for extended linear ranges and higher durability. -
Q: Can this sensor be used independently without a converter?
A: No, the sensor must be used with the CON011 converter module to produce a usable output signal. -
Q: What is the typical output signal from the sensor?
A: The sensor, when paired with CON011, provides a voltage signal proportional to displacement—typically 7.87 mV/µm. -
Q: Is the sensor suitable for high-temperature applications?
A: Yes, it can operate up to +180°C, depending on the cable and mounting configuration. -
Q: Can this be used on non-ferromagnetic targets?
A: No, optimal performance is achieved only with ferromagnetic materials like 4140 steel. -
Q: What tools are needed for installation?
A: A standard mounting bracket or threaded port (M14x1.5), torque wrench, and alignment gauge are typically required. -
Q: Can the cable length be customized?
A: Yes, Epro supplies various cable lengths from 3 m to over 10 m, pre-assembled and factory calibrated. -
Q: Does this sensor support dynamic vibration measurement?
A: Yes, it supports both static (gap) and dynamic (vibration) measurements. -
Q: Is it compatible with Bently Nevada or other third-party systems?
A: It is designed specifically for Epro CON011 + MMS systems; compatibility with third-party systems requires custom integration. -
Q: What is the warranty period for this sensor?
A: We provide one year warranty.
