EPRO CON021+PR6424/000-000 Vibration Sensor System

The EPRO CON021 + PR6424/000-000, also cataloged as the CON021 + PR6424 Vibration Sensor System, operates as a dedicated hardware component for non-contact radial shaft vibration and displacement measurement within MMS6000 shaft monitoring platforms.

Hardware Specifications

Eddy-Current Probe Scaling & Gap Voltage Validation

The combined eddy-current sensing system utilizes high-frequency electromagnetic field output from the 8 mm PR6424 probe tip to measure target movement relative to the sensor face. Internal signal conditioning inside the CON021 converter provides precise eddy-current probe scaling at -7.87 V/mm (-200 mV/mil) over a 0 Hz to 10 kHz frequency response spectrum. During mechanical alignment, gap voltage validation targets a nominal -12 V DC operational center point (corresponding to gap targets within the linear dynamic range), allowing accurate measurement of dynamic rotor dynamics without signal clipping.

Frequently Asked Questions

Q: What is the nominal supply voltage required for the CON021 signal converter?

A: The converter requires a nominal power supply of -24 V DC, operating within an allowable input range of -18 V to -30 V DC.

Q: How is the physical gap zero-point validated during probe installation?

A: Mechanical insertion depth is adjusted while observing sensor voltage until reaching a nominal gap voltage of -12 V DC on the output terminals.

Field Installation Guidelines

• Mount the PR6424 sensor head rigidly to the bearing housing to eliminate mechanical resonance in the measurement axis.
• Secure the 5 m total cable system using LEMO connector fittings, avoiding tight bend radii along the extension lead.
• Maintain minimum lateral clearance around the 8 mm probe tip to prevent side-wall crosstalk suppression issues with nearby ferrous structures.
• Ensure the CON021 signal conditioner is grounded and housed within an IP-rated enclosure to shield against industrial EMI.
