Product Overview

The Emerson EPRO PR6426/000-030 represents a critical sensing component for high-integrity machinery protection. This 8mm eddy current proximity probe measures shaft vibration, radial displacement, and eccentricity in high-speed rotating equipment without physical contact. It operates primarily with EPRO CON signal converters (such as the CON021) and integrates directly into MMS6000 or MMS3000 monitoring racks. We deliver this unit as 100% Brand New and Factory Sealed, ensuring laboratory-grade precision for turbines, compressors, and gearboxes.

Technical Specifications

The PR6426/000-030 features a ruggedized construction designed for high-stress industrial environments.

Engineering Advantages

• Non-Contact Precision: The probe utilizes electromagnetic induction to detect surface proximity. This eliminates mechanical wear and friction, allowing for continuous monitoring at surface speeds that would destroy contact-based sensors.

• Extreme Environment Durability: The stainless steel housing and specialized tip material resist degradation from industrial lubricants, moisture, and dust. It maintains signal stability even under significant thermal cycling in steam turbine housings.

• Optimized Signal Path: The integrated 3.0m cable features high-quality shielding to prevent electromagnetic interference (EMI). This ensures that the raw signal remains pure until it reaches the signal converter, preventing "false vibration" readings caused by nearby electrical noise.

• Standardized Calibration: This model follows the industry-standard scale factor (typically 8V/mm when used with the correct converter). This consistency simplifies the commissioning process for large-scale machinery protection systems.

FAQs

• Does the PR6426/000-030 require a signal converter to function?

  Yes. Like all passive eddy current probes, the PR6426/000-030 requires an external driver/converter (such as the EPRO CON021) to generate the oscillation and translate the proximity change into a standardized voltage signal.

• Can I shorten or extend the integrated 3.0m cable?

  We strongly advise against modifying the cable length. The internal impedance of the 3.0m cable is a critical part of the sensor's calibration. Altering the length will shift the linear measurement range and invalidate the factory calibration settings.

• How do I ensure the probe is correctly gapped during installation?

  Connect the probe to its converter and power supply. Use a multimeter to measure the "Gap Voltage" at the converter output. Adjust the physical position of the probe until the DC voltage reaches the center of the linear range (typically -10V DC for most EPRO systems).

• Is this probe compatible with Bently Nevada Proximitor systems?

  While EPRO and Bently Nevada both utilize eddy current technology, the impedance and calibration curves differ. Always cross-reference the scale factor ($V/mm$ or $mV/mil$) of your existing system before replacing a Bently probe with an EPRO PR6426.
