Quick Detail

Description

The Bently Nevada 330780-50-00 3300 XL 11 mm Proximitor Sensor is the intelligent signal conditioning heart of the industry-leading 11 mm proximity transducer system. This panel-mounted sensor is specifically engineered to convert the raw, high-frequency signal from an eddy current proximity probe into a stable, high-fidelity DC voltage output that accurately represents the dynamic gap between the probe tip and a rotating shaft. With a total system cable length of 5.0 meters (16.4 feet) integrated into its design, the sensor is optimized for direct connection to a 3300 XL 11 mm probe, providing a complete, calibrated measurement loop ideal for monitoring axial position and radial vibration on large turbomachinery such as steam turbines and centrifugal compressors. Its robust construction, housed in a 140 mm overall case, ensures reliable performance in the demanding environments of power generation and heavy industry.

Electrical precision is paramount for machinery protection, and the 330780-50-00 Proximitor Sensor delivers exceptional performance. It operates within a wide power supply range of -17.7 Vdc to -25 Vdc and exhibits minimal supply sensitivity of less than 2 mV/V, ensuring its output is impervious to typical power rail fluctuations found in industrial settings. The sensor is meticulously calibrated to work in conjunction with 3300 XL 11 mm extension cables, which have a specific capacitance of 69.9 pF/m, and maintains a stable 45 Ω output resistance. This precise electrical matching guarantees system linearity and preserves the integrity of the displacement or vibration signal across its full operating temperature range of -55°C to +185°C, one of the broadest in the industry.

Applications

This Proximitor sensor is essential for monitoring thrust bearing position and rotor vibration in large steam and gas turbines within power generation facilities. Its wide operating temperature range allows it to function reliably in the high-heat environment of a turbine deck, while its precise signal conditioning ensures accurate data is delivered to the monitoring system for protecting these critical, high-value assets from catastrophic failure.

In oil and gas applications, such as on offshore platforms or in refineries, the sensor provides reliable condition monitoring for critical rotating equipment like centrifugal compressors and large pumps. Its robust design and stable electrical output, resistant to supply voltage variations, ensure trustworthy performance in environments with potential flammable atmospheres and electrical noise, supporting safety and preventing unplanned production downtime.

For heavy industrial machinery including large motors, fans, and gearboxes in sectors like mining and metals, this sensor converts probe signals into actionable data for predictive maintenance programs. Its panel-mount design and standard field wiring compatibility allow for easy integration into existing motor control centers, enabling continuous monitoring to detect misalignment, imbalance, and bearing defects before they lead to operational failures.

Specifications

Competitive Advantage

1.Industry-Leading Thermal Tolerance for Unmatched Reliability

The sensor's exceptional operating and storage temperature range of -55°C to +185°C provides a significant performance buffer beyond standard industrial sensors. This extreme thermal resilience ensures stable, accurate signal conditioning in environments where ambient temperatures are highly volatile, such as inside turbine enclosures or in outdoor arctic conditions, eliminating a common point of failure and expanding its viable application footprint.

2.Optimized System Integration with Precision Electrical Matching

Unlike generic signal conditioners, this Proximitor sensor is electrically tuned as part of the complete 3300 XL 11 mm system. Its specified output resistance and calibration for use with 69.9 pF/m extension cables guarantee optimal signal fidelity and system linearity. This plug-and-play compatibility with matched probes and cables delivers out-of-the-box accuracy, simplifies commissioning, and removes the calibration uncertainties associated with mixing components from different system generations.

3.Ruggedized Design for Demanding Industrial Service

Housed in a substantial 140 mm metal case and designed for secure panel mounting, the sensor is built to withstand the vibration, humidity, and electromagnetic interference prevalent in industrial control cabinets. Its robust construction ensures long-term reliability and consistent performance, minimizing maintenance needs and providing a dependable core for continuous machinery protection systems in critical applications.
