The EPRO PR6423/290-110 is a non-contact eddy current displacement sensor engineered for radial vibration monitoring with extended standoff capability. This specialized probe operates seamlessly with EPRO CON011 and PR6423 series driver modules. It provides reliable measurements where larger initial air gaps are unavoidable.

Extended Air Gap for Challenging Installations
The PR6423/290-110 accommodates an initial air gap up to 1.8 mm. This extended range proves essential when shaft runout exceeds normal tolerances. You also benefit from increased clearance during startup and coast-down sequences. Consequently, the risk of accidental probe contact diminishes significantly.
Specialized Mechanical Configuration
EPRO designed this variant with a 70 mm body length and reduced tip section. The 15 mm extended nose allows positioning deeper within bearing housings. You mount the PR6423/290-110 without requiring custom adapter brackets. Two included lock nuts secure the precise axial position after gap setting.
Passive Circuitry for Maximum Reliability
This sensor contains no internal amplifiers or energy storage components. The passive eddy current coil reflects impedance changes directly to the driver. Therefore, you experience zero electronic drift over time. The PR6423/290-110 maintains calibration indefinitely under normal operating conditions.
Environmental Resistance Specifications
You can expose this probe to continuous temperatures reaching +180 °C at the tip. The stainless steel housing resists corrosion from lubricating oil and steam. IP68 protection allows temporary submersion during machine washdown procedures. Fluorocarbon cable insulation withstands aggressive industrial solvents.
System Compatibility and Signal Output
The PR6423/290-110 connects directly to EPRO CON011 series driver converters. Your existing PR6423 system recognizes this sensor without modification. The driver produces a linear voltage output proportional to target distance. Many protection systems, including RMS series monitors, accept this signal directly.
Application Versatility
You will find this sensor ideal for large steam turbines and centrifugal compressors. The extended air gap accommodates thermal growth without re-zeroing. Additionally, the longer body reaches recessed shaft surfaces inaccessible to standard probes. This flexibility reduces mechanical modification costs during retrofits.
