Description
The 3300 XL 8 mm Proximity Transducer System consists of: o One 3300 XL 8 mm probe, o One 3300 XL extension cable1 , and o One 3300 XL Proximitor
Sensor2. 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 measurements3. 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 nonXL 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 space6,7.
Proximitor Sensor
The 3300 XL Proximitor Sensor incorporates numerous improvements over previous designs. Its physical packaging allows you to use it in high-density DIN-rail
installations. You can also mount the sensor in a traditional panel mount configuration, where it shares an identical 4-hole mounting “footprint” with older
Proximitor Sensor designs. The mounting base for either option provides electrical isolation and eliminates the need for separate isolator plates. The 3300 XL
Proximitor Sensor is highly immune to radio frequency interference, allowing you to install it in fiberglass housings without adverse effects from nearby radio
frequency signals. The 3300 XL Proximitor Sensor’s improved RFI/EMI immunity satisfies European CE mark approvals without requiring special shielded
conduit or metallic housings, resulting in lower installation costs and complexity. The 3300 XL’s SpringLoc terminal strips require no special installation tools
and facilitate faster, more robust field wiring connections by eliminating screw-type clamping mechanisms that can loosen.
Proximity Probe and Extension Cable
The 3300 XL probe and extension cable also reflect improvements over previous designs. A patented TipLoc molding method provides a more robust bond
between the probe tip and the probe body. The probe’s cable incorporates a patented CableLoc design that provides 330 N (75 lbf) pull strength to more
securely attach the probe cable and probe tip. You can also order 3300 XL 8 mm probes and extension cables with an optional FluidLoc cable option. This option
prevents oil and other liquids from leaking out of the machine through the cable’s interior.
Specifications
Unless otherwise noted, the following specifications are for a 3300 XL 8 mm Proximitor Sensor, extension cable and 8 mm probe between +18˚C and +27˚C
(+64˚F to +80˚F) at a maximum altitude of 2000 meters, with a -24 Vdc power supply, a 10 kΩ load, an AISI 4140 steel target, and a probe gapped at 1.27 mm
(50 mils). Performance characteristics apply to systems that consist solely of 3300 XL 8 mm components. The system accuracy and interchangeability
specifications do not apply to transducer systems that are calibrated to any target other than our AISI 4140 steel target.
Bently Nevada 330130-040-00-00 3300 XL Standard Extension Cable
The Bently Nevada 330130-040-00-00 is a 4.0-meter standard extension cable belonging to the 3300 XL series, specifically designed for the 8mm proximity
transducer system to connect probes with proximitor sensors in industrial rotating machinery monitoring. Constructed with 75 triaxial fluoroethylene propylene
(FEP) insulation, it delivers stable signal transmission with typical capacitance of 69.9 pF/m, minimizing attenuation and electromagnetic interference to ensure
accurate capture of vibration, position, and rotational speed data. Equipped with user-friendly Click Loc connectors and compliant with API 670 4th edition
standards, this durable, U.S.-made accessory features a compact design for easy installation and integration, making it ideal for condition monitoring and
predictive maintenance in power plants, petrochemical facilities, and heavy industry—effectively supporting early fault detection, reducing downtime, and
optimizing operational efficiency of critical equipment like turbines, compressors, and pumps.
Bently Nevada 330101-00-12-05-02-00 : 3300 XL 8mm Proximity Probe
As a key component of Bently Nevada’s 3300 XL series, the 330101-00-12-05-02-00 is an 8mm proximity probe engineered for non-contact condition
monitoring of industrial rotating machinery, leveraging the eddy current principle to deliver precise measurements of shaft vibration, axial position, and
rotational speed. With a measurement range of 0.25 to 2.3 mm, ±1% linearity across the full range, and temperature compensation technology, it maintains
stable performance in harsh environments ranging from -40°C to +120°C, while its corrosion-resistant stainless steel construction and gold-plated Click Loc
connector ensure durability and reliable signal transmission. Fully compliant with API 670 standards and compatible with 3300 XL series proximitors and
extension cables, this probe is widely used in power generation, petrochemical, and heavy industry for monitoring critical equipment like steam turbines, gas
turbines, and centrifugal compressors, supporting predictive maintenance to minimize downtime and enhance operational safety.
Bently Nevada 330180-50-00 3300 XL Proximitor Sensor
The Bently Nevada 330180-50-00 is a high-performance proximitor sensor of the 3300 XL series, specifically designed to pair with 8mm proximity probes for
non-contact condition monitoring of industrial rotating machinery. It converts eddy current signals from the probe into linear voltage outputs proportional to
shaft vibration, axial displacement, and rotational speed, featuring high signal-to-noise ratio and ±0.5% measurement accuracy to ensure reliable data for
predictive maintenance. Built with rugged industrial-grade housing, it withstands extreme temperatures (-40°C to +125°C) and harsh operating environments,
while full compliance with API 670 standards guarantees compatibility with critical equipment in power plants, petrochemical facilities, and heavy industry—
