The 330101-00-12-05-01-05 is an unarmored 3/8-24 UNF threaded probe. It features a 1.2-inch case thread length, a 0.5-meter total length, and a 3/8-24 threaded coaxial connector, with hazardous area approvals and safety certifications from multiple countries.
One 3300 XL 8 mm probe
One 3300 XL extension cable
One 3300 XL Proximitor Sensor
The system provides an output voltage that is directly proportional to the distance between the probe tip and the observed conductive surface and can measure both static (position) and dynamic (vibration) values. The system’s primary applications are vibration and position measurements on fluid-film bearing machines, as well as Keyphasor reference and speed measurements.
The 3300 XL 8 mm system delivers the most advanced performance in our eddy current proximity transducer systems. The standard 3300 XL 8 mm 5-meter system also fully 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 of performance and support complete interchangeability of probes, extension cables, and Proximitor sensors, eliminating the need to match or bench calibrate individual components. Each 3300 XL 8 mm Transducer System component is backward compatible and interchangeable4 with other non XL 3300 series 5 mm and 8 mm transducer system components5. This compatibility includes the 3300 5 mm probe, for applications in which an 8 mm probe is too large for the available mounting space.

Oil and Gas Refining
Vibration and axial position monitoring on critical turbomachinery, such as wet gas compressors and catalytic cracker air blowers, to prevent catastrophic failure and ensure continuous refinery operation.
Thermal Power Generation
Radial vibration monitoring and oil-film thickness measurement on main steam turbines, generator shafts, and boiler feed pumps to prevent rotor-to-stator rubs and optimize maintenance schedules.
Nuclear Power Plants
High-precision shaft relative vibration and thrust position monitoring on reactor coolant pumps and high-pressure steam turbines to meet stringent safety and regulatory compliance standards.
Hydroelectric Power Generation
Dynamic runout measurement and shaft alignment monitoring on large, vertical hydro-turbine generators and cooling water pumps to detect blade imbalances or hydraulic turbulence.
Steel and Metallurgical Industry
Vibration and bearing wear monitoring on high-capacity blast furnace blowers, hot rolling mill drives, and oxygen compressor units subjected to harsh, heavy-load environments.
Pulp and Paper Manufacturing
Dynamic monitoring of high-speed paper machine drying cylinders, vacuum pumps, and large refiner shafts to avoid roll damage and maintain consistent paper quality.
The 330101-00-12-05-01-05 probe requires strict monitoring of the static gap voltage during use to ensure it is adjusted to the linear center zone of approximately minus 10 volts DC during installation and firmly locked in place with a locknut. When connecting cables, proper mating must be performed via the integral polarized miniature coaxial connector, and a connector protector must be applied to isolate external oil contamination, guaranteeing signal transmission quality across a wide temperature range from minus 51 degrees Celsius to 177 degrees Celsius.
Additionally, a detailed inspection must be executed on the metal shaft surface to eliminate scratches, oil sludge, and residual magnetism, preventing mechanical and electrical runout errors from interfering with the system's micron-level vibration and displacement monitoring.
This is a 3300 XL 8 mm non-contact proximity probe for measuring shaft vibration and displacement in rotating machinery. It features a 3/8-24 threaded case with a 0-inch unthreaded length, a 1.2-inch case length, and a 0.5-meter cable with a ClickLoc connector and hazardous area approvals. Operating from −51 °C to +177 °C, it penetrates oil films to track real-time machine behavior.
330101-00-12-05-01-05 is a 3300 XL 8 mm Proximity Probe.
What is the measurement principle of the 330101-00-12-05-01-05?
It utilizes the eddy current principle, where a high-frequency coil in the probe tip generates an alternating electromagnetic field on the metal shaft surface, converting the gap distance into a high-frequency electrical signal.
What specific measurement tasks can the 330101-00-12-05-01-05 execute?
It can measure radial shaft vibration, axial thrust displacement, Keyphasor references, and rotational speed on fluid-film bearing machines.
How to install and use the 330101-00-12-05-01-05 on-site?
Screw it into the mounting hole on the bearing housing using its standard 3/8-24 fractional threads, adjust the static gap between the probe tip and the shaft surface, and then secure it with a locknut.
Which components must the 330101-00-12-05-01-05 pair with to operate properly?
It must be connected through an extension cable to a matching 3300 XL Proximitor sensor to form a complete transducer system.
