Technical Specifications

Measurement Principle

The probe operates using eddy-current technology to detect the distance between the probe tip and a conductive target surface. Variations in shaft position alter the electromagnetic field generated by the probe, producing a corresponding signal that represents displacement.

When installed as part of a complete 3300 XL transducer system, the probe provides the displacement information required for machinery vibration monitoring, thrust position measurement, and rotational reference applications.

Mechanical Construction

The sensing tip is manufactured from PPS material, while the probe housing is constructed from AISI 303 or AISI 304 stainless steel. This combination provides mechanical durability and dimensional stability for long-term installation in rotating equipment monitoring systems.

The ClickLoc connector design helps secure the connection between the probe and extension cable while simplifying installation and maintenance activities.

API 670 Compliance

The 3300 XL 8 mm probe is designed to meet the mechanical configuration, linear range, accuracy, and temperature stability requirements associated with API 670 machinery protection applications. This makes it suitable for use within vibration monitoring systems used on critical rotating equipment.

Application Use

This probe is commonly used for:

• Radial shaft vibration measurement

• Axial shaft position monitoring

• Differential expansion measurement

• Rotational speed sensing

• Keyphasor reference generation

• Rotor dynamic analysis

Its 2 mm linear measurement range and 200 mV/mil scale factor allow accurate measurement of shaft displacement within the calibrated operating region of the transducer system.
