Product Introduction
The Epro PR6424/013-130 is a high-precision, non-contact eddy current sensor used for measuring the vibration and axial displacement of rotating machinery. This 16mm proximity probe is a critical component of the Epro PR6424 series, engineered for deployment in industrial environments such as power plants, refineries, and chemical processing units.
The PR6424/013-130 is designed to function with companion converter modules such as CON021 or CON041, delivering a stable, linear output across a defined measurement range. Built to withstand high temperatures, mechanical stress, and electromagnetic interference, the sensor ensures reliable monitoring and protection of critical rotating assets.

FAQ
-
Which converter modules are compatible with the PR6424/013-130 sensor?
The sensor is designed to be used with Epro CON021 or CON041 converter modules. -
Can I extend or shorten the factory cable length?
No, the cable and converter are calibrated as a matched pair; altering the cable length invalidates calibration. -
What is the output voltage signal range?
The system outputs an analog voltage, typically 0–20 VDC, depending on the CON module. -
Is this sensor suitable for high-speed rotating machinery?
Yes, with a 10 kHz frequency response, it is well-suited for high-speed shaft monitoring. -
Can this sensor operate in oil-lubricated or contaminated environments?
Yes, it features a robust stainless steel housing and is sealed to IP65/IP67 ratings. -
Does the sensor support integration with third-party monitoring systems?
Yes, as long as the output signal from the converter matches the input requirements of the system. -
What is the effect of temperature variation on sensor accuracy?
The system is temperature-compensated and remains stable within the specified operating range. -
Is the sensor protected against reverse polarity?
Protection is handled by the converter module, not the sensor head itself. -
Can it be used for axial as well as radial measurements?
Yes, depending on the orientation of installation, it supports both types. -
How is linearity affected by mounting distance?
Mounting distance is critical. Deviation from factory-recommended gap can affect linearity and sensitivity.
