Description
The Emerson Epro PR6423/000-031 is a high-precision, non-contact eddy current sensor designed for displacement and vibration monitoring in critical rotating machinery. As a key component of the Epro AMS series, this 8 mm probe measures the distance between the sensor tip and a conductive target, converting it into a proportional electrical signal. It is essential for monitoring steam turbines, compressors, and gearboxes, enabling predictive maintenance by detecting shaft misalignment or bearing wear early to prevent unplanned downtime.
Features
-
Non-Contact Measurement: Uses the inductive eddy current principle for wear-free operation.
-
Robust Construction: Features a high-grade stainless steel housing and a PPS (polyphenylene sulfide) probe tip resistant to high-pressure lubricants and aggressive industrial fluids.
-
High-Temperature Tolerance: Designed for demanding environments with an operating temperature range up to 150 degC for the sensor head.
-
Pressure Resistant: Capable of withstanding up to 700 kPa (7 bar) at the probe tip.
-
Predictive Maintenance: Provides critical data for vibration analysis and shaft position monitoring.
Applications
- Power generation facilities (steam and gas turbines).
- Petrochemical and oil & gas processing plants.
- Heavy industrial mining equipment.
- Compressor and pump monitoring systems.

Installation Guidelines
-
Mounting: Ensure the sensor is mounted securely using the provided thread (M10x1 or 3/8-24 UNF). Avoid over-tightening to prevent damage to the housing.
-
Calibration: This sensor requires a compatible Epro driver/converter to linearize the output signal. Ensure the driver is calibrated for the specific target material.
-
Cable Routing: Route coaxial cables away from high-voltage power lines and sources of high electromagnetic interference (EMI) to maintain signal integrity.
-
Grounding: Ensure proper system grounding to avoid ground loops, which can introduce noise into the displacement signal.
-
Handling: The probe tip is a precision component; handle with care to avoid mechanical impact or scratches.
FAQ
Does this sensor require a specific driver?
Yes, the PR6423 series operates on the inductive eddy current principle and requires a calibrated Epro signal converter (driver) to process and linearize the output signal.
Can this sensor be used in high-pressure environments?
Yes, the sensor head is rated for pressures up to 700 kPa (7 bar), making it suitable for installation in pressurized lubrication or hydraulic systems.
