Compatible Equipment

The EPRO PR6423/012-100 is fully compatible with industrial monitoring systems:

Signal Converters: CON 011 converters are necessary for raw eddy current signal processing to ensure standardized outputs (4-20 mA or 0-10 V) for easy integration with PLC or DCS systems for real-time data analysis.

Turbine and compressor monitoring platforms for MMS 6000/3000 machinery protection systems for continuous monitoring of shaft eccentricity, vibration and axial displacement.

Installation Accessories: The MPT 064 stainless steel protection tube or the EZ 1600 probe holders can be used to stabilize the sensor body of the high speed rotating machinery on which measurements are performed.

Application Scenarios

Monitoring of Turbine Shafts: This measurement detects misalignment or bearing wear by measuring axial and radial displacement in steam/gas turbines and thus prevents major failures. In combined-cycle power plants, for instance, it provides safe separation between rotating and stationary components.

Compressor Vibration Analysis — Tracks dynamic eccentricity in higher-speed compressors (for example: offshore gas processing units) to optimize efficiency and mitigate expenses by identifying risks of rotor imbalance.

Pump Bearing Lubrication Control: Monitors the thickness of the oil film in hydro pumps and provides early warning of lubrication failure. It is very important for hydropower plants running at variable loads.

Installation & Maintenance

Mounting: The EPRO PR6423/012-100 features an M10x1 or 3/8"-24UNF thread for flexible positioning. Ensure a minimum shaft diameter of 25 mm and an initial air gap of 0.5 mm (±0.1 mm) to maintain measurement accuracy. Use torque-limiting tools to avoid over-tightening.

Cabling: Armored cables (6 mm diameter) with a minimum bending radius of 35 mm are recommended for high-stress routing near rotating equipment or in confined spaces.

We also supply other models of this products: PR6423/012-120, PR6423/014-130, PR6423/015-110.They are the same in specifications, features and application range. The difference is the total length of the cable and thread length, refer to the table for details.
