Description：

The system provides an output voltage that is directlyproportional to the distance between the probe tip and theobserved conductive surface and can measure both static(position) and dynamic (vibration) values. The system'sprimary applications are vibration and position measurements on fluid-film bearing machines, as well as Keyphasor reference and speed measurements3.

The 3300 XL 8 mm system delivers the most advancedperformance in our eddy current proximity transducersystems. The standard 3300 XL 8 mm 5-meter system alsofully complies with the American Petroleum Institute's (API)670 Standard for mechanical configuration, linear range,accuracy, and temperature stability. All 3300 XL 8 mm proximity transducer systems provide this level ofperformance and support complete interchangeability ofprobes, extension cables, and Proximitor sensors, eliminatingthe need to match or bench calibrate individual components.

Frequently asked questions

Q : What is the physical diameter of this probe tip?

A: It belongs to the 8mm probe series, referring to the diameter of the non-metallic PPS tip.

Q : What does the base model number "330103" indicate?

A: It specifies a metric threaded housing with a standard thread size of M10 × 1.

Q : What target material is this probe calibrated for?

A: It is calibrated by default for AISI 4140 steel. Measuring stainless steel or aluminum requires a specially calibrated Proximitor sensor.

Q : What is the nominal supply voltage for the Proximitor sensor?

A: The Proximitor sensor requires a steady external DC power supply of -24 Vdc

Q : Can I replace this probe with the global standard part 330103-00-25-05-02-00?

A: Yes. The physical footprint and electrical properties are 100% identical. The standard global part is an exact drop-in replacement.

Product Applications

Thermal and hydroelectric power plants: Monitoring bearing vibration and shaft displacement in steam turbines, generators, large water pumps, and fans.

Oil refineries and chemical plants: Used for condition monitoring of large centrifugal compressors, reciprocating compressors, industrial gearboxes, and fans.

Steel and mining enterprises: Installed on heavy-duty rolling mills, large blowers, and generator sets to enable predictive maintenance and prevent sudden mechanical damage.
