Technical Specifications
- Product Series: 3300 XL 8mm Proximity Probe
- Part Number: 330105-02-12-90-00-05
- Probe Diameter: 8 mm
- Thread Type: M10×1 metric
- Unthreaded Length: 0.2 inch (approximately 5 mm)
- Overall Case Length: 1.2 inch (approximately 30 mm)
- Total Cable Length: 9.0 meters
- Connector Type: No connector, standard cable
- Agency Approval: Multi-agency approval (CSA, ATEX, IECEx)
Functional Features
- Non-Contact Measurement: Provides precise measurement of both static position and dynamic vibration without physical contact.
- High Sensitivity: Delivers 7.87 V/mm (200 mV/mil) output for accurate detection of minute vibration changes.
- API 670 Compliance: Meets API 670 requirements for mechanical configuration, linear range, accuracy, and temperature stability.
- System Interchangeability: Fully interchangeable with other 3300 XL 8mm proximity probes.
- Extended Cable Length: The 9.0 meter total cable length is designed for installations where the Proximitor is mounted at a significant distance from the probe.
Application Scenarios
Used in fluid film bearing machines for radial vibration monitoring, axial displacement measurement, Keyphasor reference, and speed measurement. The extended cable length is suitable for applications where the Proximitor must be mounted remotely from the probe location, such as in large turbine installations or where environmental conditions require the Proximitor to be placed in a protected enclosure.

Material Composition
Stainless steel probe body with precision-wound internal coil, TipLoc patented molding technology, CableLoc patented cable retention design.
Structural Characteristics
Cylindrical 8mm diameter probe with M10×1 metric mounting thread. The probe features an integrated 9.0 meter standard cable without a connector, allowing direct termination at the Proximitor or junction box. The 0.2 inch unthreaded length and 1.2 inch case length provide a compact form factor for installations with limited axial space.
Working Principle
The probe coil generates a high-frequency magnetic field, and eddy currents induced in the conductive target surface alter the coil impedance proportionally to the gap distance. The Proximitor detects this impedance change and converts it into a DC voltage output.
Installation Requirements
Mount the probe using the M10×1 metric thread in a tapped hole on the machine bearing housing. Ensure the probe tip is perpendicular to the target surface. The total system electrical length must match the Proximitor rating.
Usage Notes
Verify the target surface is clean and smooth before installation. The recommended initial gap setting is 1.27 mm (50 mils). Ensure the 9.0 meter total cable length exactly matches the Proximitor’s rated system length. Handle the cable carefully to avoid damage during routing.
