Technical Parameters & Selection Guide

Selection Criteria: Choose this 8mm probe for machinery with M10 threaded mounting provisions and shaft diameters exceeding 50mm. For smaller shafts (25-50mm), consider 5mm probe variants. Verify proximitor sensor compatibility—this probe requires -24 VDC excitation systems. For cable runs exceeding 1.2m, specify extension cables in 1-meter increments up to 9 meters total system length.

Extended Functions

Multi-Channel Synchronization: Deploy in XY probe pairs for orbit analysis and phase discrimination, enabling precise diagnosis of unbalance, misalignment, and looseness conditions through Bode plots and polar plots.

Keyphasor Integration: Combine with once-per-revolution tachometer probes to generate time-domain waveforms and cascade plots, revealing rotor crack propagation and rub events invisible to single-channel monitoring.

IoT Connectivity Options: Interface with wireless vibration transmitters and cloud-based analytics platforms for remote monitoring, automated alarm notification, and machine learning-based anomaly detection across distributed asset portfolios.

Customization Available: Factory can modify cable lengths (0.5m to 9m), apply special coatings for extreme chemical exposure, or provide matched probe sets with <0.5% sensitivity variation for critical differential expansion measurements.

Delivery & Service Assurance

Lead Time: Standard configuration ships within 3-5 business days from regional distribution centers in North America, Europe, and Asia-Pacific. Custom cable lengths require 2-3 weeks factory lead time.

Warranty Coverage: 12-month comprehensive warranty covers defects in materials and workmanship under normal operating conditions. Extended 36-month coverage available for critical spares programs.

Technical Support: Application engineering assistance provided for system design, installation troubleshooting, and calibration verification. Field service available for commissioning support and training at customer facilities.

Documentation Package: Each unit includes calibration certificate with sensitivity curves, installation instructions with torque specifications, dimensional drawings, and material certifications (MTRs) for pressure equipment compliance.

Frequently Asked Questions

What proximitor sensor models are compatible with this 8mm probe?
This probe operates with any proximitor sensor accepting 8mm probe inputs, including legacy 7200 series and current 3300 XL platforms. Verify your sensor accepts -24 VDC excitation and provides -8 to -10 VDC gap voltage output.

Can I install this probe in ATEX Zone 1 hazardous areas?
Yes, when used with intrinsically safe barriers and certified proximitor sensors rated for Zone 1 applications. The probe itself is a passive device; hazardous area certification depends on the complete system configuration including barriers and sensor electronics.

How do I determine the correct installation gap distance?
Optimal gap is 40-60 mils (1.0-1.5mm) from the target surface, corresponding to -9 VDC nominal output. Use a feeler gauge during installation and verify gap voltage with a DVM. Consult the calibration curve supplied with your proximitor sensor for precise gap-to-voltage correlation.

What is the maximum shaft speed this probe can monitor?
With 10 kHz bandwidth, the probe accurately measures vibration at shaft speeds up to 600,000 RPM (10,000 Hz). Practical upper limit is typically 30,000 RPM for turbomachinery applications, well within the probe's frequency response capability.

Does the probe require periodic recalibration?
No field recalibration is required. The eddy current sensing principle is inherently stable, with typical drift <1% over 10-year service life. Verification against a calibration standard is recommended every 5 years for critical safety systems or regulatory compliance.

Can I extend the cable length if 1.2 meters is insufficient?
Yes, use factory-supplied extension cables in 1-meter increments. Maximum total system length (probe cable + extension) is 9 meters. Longer cable runs increase system capacitance, requiring proximitor sensor output adjustment to maintain calibration accuracy.
