Functional Description

The 330102‑00‑20‑15‑02‑00 probe forms part of a three‑component transducer system consisting of the probe, extension cable, and Proximitor sensor. The probe generates a voltage proportional to the distance between the probe tip and the rotating shaft surface, enabling accurate monitoring of:

• Shaft radial vibration

• Axial position

• Thermal growth

• Keyphasor phase reference

• Speed measurement

Its stainless steel housing and armored cable options support installation in demanding environments. The probe maintains the same mounting pattern as earlier 3300 designs, simplifying upgrades and retrofits. With standardized electrical characteristics and full component interchangeability, the probe ensures consistent performance across new and existing systems.

Application Scenarios

• Steam and gas turbines

• Centrifugal compressors

• Industrial pumps

• Gearboxes and generators

• Oil & gas, power generation, and heavy industrial machinery

FAQ

Q: Is this probe compatible with older 3300 systems?  A: Yes. It is electrically and mechanically interchangeable with both XL and non‑XL 3300 components when matched by cable length.

Q: What is the typical linear range of an 8 mm probe?  A: Approximately 2 mm, depending on calibration and target material.

Q: Can this probe be used for Keyphasor applications?  A: Yes. When paired with the appropriate Proximitor module, it supports phase reference and speed measurement.
