Features:
- Serves as the Signal Conditioning Interface Between the Probe and Monitoring System
- Integrates Advanced Proximity Sensing with Extended System Length Configuration
- Functions Seamlessly with 3300 XL Monitoring Systems and Bently Nevada Machinery Protection Platforms
The 330780-91-05 operates as the 3300 XL 11 mm Proximitor Sensor in a vibration monitoring system, providing reliable signal conditioning for eddy current proximity measurements. It continuously processes the electrical signal generated by the matched probe and cable assembly, converting the impedance changes into a proportional voltage output that accurately represents the target gap distance. Consistent measurement accuracy is standard with the 3300 XL series, and the 330780-91-05 maintains this precision across its full 9.0 meter (29.5 feet) system length. The 330780-91-05 has incorporated several design improvements over previous proximitor generations in addition to supporting universal compatibility with existing 3300 series installations.
The 330780-91-05 provides essential signal conditioning functions common to the entire measurement path, and is a critical component of the monitoring chain, directly affecting the proper, normal operation of the overall vibration monitoring system. One 330780-91-05 proximitor is required per measurement channel depending on the desired monitoring configuration. The 330780-91-05 occupies a compact housing designed for DIN rail mounting and is typically located within the equipment cabinet or junction box near the monitored machine.
For extended system length applications, the 330780-91-05 supports the full 9.0 meter system length without requiring additional signal boosters or repeaters. In addition to standard single-channel operation, the 3300 XL architecture also supports multi-channel configurations. The 3300 XL system executes signal distribution using the internal circuitry specified in the proximitor design. Using this method, the monitoring system continually processes the health of the vibration signal. If the system detects that the probe gap is outside the linear range or that the signal quality has degraded, it will automatically flag the condition and place an event in the System Event List.
The 330780-91-05 Bently Nevada 3300 XL 11 mm Proximitor Sensor may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).
