EPRO PR6424/010-100 Proximity Sensor Module

Configured for shaft vibration and relative displacement monitoring in rotating machinery monitoring systems, the EPRO PR6424/010-100 (PR6424 Proximity Sensor Module) provides direct physical execution.

Suffix Breakdown & Model Matrix

• Base Model (PR6424): Non-contact eddy-current proximity probe series designed for static and dynamic shaft displacement measurements.
• Suffix (/010-100): Specifies the internal body execution, thread mounting configuration, integrated cable length, and connector termination arrangement.

Hardware Specifications

Channel-to-Channel Isolation & Signal Conditioning

When integrated into process control systems, raw eddy-current signals from the probe pass through dedicated signal converters to deliver standardized process outputs. Incorporating channel-to-channel isolation within the measurement loop prevents ground loops and eliminates noise pickup across long distance cable runs in high-density DCS instrumentation cabinets.

Frequently Asked Questions

Q: Does the PR6424/010-100 probe require direct DC supply voltage at the terminal connections?

A: No, the passive probe element receives high-frequency excitation voltage directly from its associated signal converter module rather than an external DC power supply.

Q: How is the physical measurement range adjusted during field installation?

A: Measurement range center-point setting requires measuring the DC gap voltage at the converter output terminals to establish correct nominal mechanical clearance from the shaft surface.

Field Installation Guidelines

• Ensure a minimum of 5 full threads of engagement when mounting the sensor into tapped machine casing ports.
• Route extension cabling through grounded metal conduit, isolated from high-voltage motor conductors and variable frequency drive (VFD) power wiring.
• Verify that signal cable shielding terminates at a single grounding point, typically at the monitor rack cabinet barrier, to prevent ground loop currents.
• Confirm mechanical clearance across 360 degrees of shaft rotation using a feeler gauge prior to applying power to the signal conditioning unit.
