3. Product features and technical highlights
High-precision non-contact measurement: The 330104-00-08-90-02-05(CN) adopts eddy current technology to realize non-contact measurement. In a high-speed motor, the rotating shaft runs at thousands of revolutions per minute. Traditional contact measurement methods will cause wear to both the probe and the shaft, while this proximity probe avoids direct contact. It can accurately measure the radial vibration and axial displacement of the shaft, with a sensitivity of 8.0 V/mm, which can detect even 0.1 mm displacement changes. This high precision ensures that potential faults can be found in advance.
Wide frequency response range: With a frequency response from DC to 10 kHz, the probe can capture both static displacement (such as shaft thermal expansion) and dynamic vibration (such as vibration caused by bearing defects). In a steam turbine, during startup and shutdown, the shaft will have thermal expansion and contraction (low-frequency static displacement), and during normal operation, it will generate high-frequency vibration due to rotor imbalance. The wide frequency response of this probe can fully record these signals, providing comprehensive data for machinery condition assessment.
Excellent environmental adaptability: The operating temperature range of -54°C to +121°C allows the probe to work in various harsh environments. In an oil refinery, the equipment near the distillation tower is in a high-temperature environment, while the outdoor pump in winter may face extremely low temperatures. The 330104-00-08-90-02-05(CN) can maintain stable performance in these environments, ensuring continuous and reliable data collection.
Reliable signal transmission: The 9.14-meter cable is made of high-quality materials with good shielding performance, which can effectively resist electromagnetic interference in industrial environments. In factories with many motors and frequency converters, electromagnetic interference is strong, but the shielded cable ensures that the signal from the probe to the monitoring system is not distorted, ensuring the accuracy of measurement data.
Easy integration with monitoring systems: The probe is specially designed to be compatible with BENTLY NEVADA’s series of monitoring systems. It can be quickly connected to the proximitor and data acquisition unit, reducing the difficulty of system integration. During installation, there is no need for complex debugging, which shortens the construction period.
4. Typical application scenarios
Turbine monitoring in power plants: In thermal power plants, steam turbines are core equipment. The 330104-00-08-90-02-05(CN) is installed near the turbine shaft to monitor radial vibration and axial displacement. When the turbine operates, if the bearing wears, the shaft will have abnormal vibration. The probe can detect this change in time and transmit the data to the monitoring system. Operators can judge the health status of the turbine according to the data, and arrange maintenance before a major failure occurs, ensuring the stable operation of the power plant.
Motor and compressor monitoring in manufacturing: In a large manufacturing plant, high-power motors and air compressors are widely used. The probe is installed on the motor bearing seat and compressor rotor to monitor their vibration and displacement. For example, if the motor rotor is unbalanced, the vibration amplitude will increase. The probe can capture this signal and send an alarm through the monitoring system, prompting maintenance personnel to balance the rotor, avoiding motor damage caused by long-term unbalanced operation.
Pump monitoring in oil and gas industry: In oil fields and gas transmission stations, various pumps are used to transport oil and gas. The 330104-00-08-90-02-05(CN) is used to monitor the shaft vibration and axial movement of the pump. Due to the harsh working environment of the pump, bearing wear and shaft misalignment are prone to occur. The probe can detect these faults in advance, ensuring the normal operation of the pump and avoiding oil and gas leakage caused by equipment failure.

5. Installation and maintenance guidelines
Installation: Before installation, carefully read the installation manual provided by BENTLY NEVADA. Select the appropriate installation position on the machinery, ensuring that the probe is perpendicular to the target surface (shaft) and the distance between them is within the effective measurement range. Use special mounting brackets to fix the probe to prevent 松动 during machinery operation. Connect the probe cable to the proximitor according to the wiring diagram, ensuring that the connection is firm and the shielding layer is properly grounded to reduce interference. After installation, power on the system and check whether the output signal is normal.
Maintenance: Regularly inspect the probe and cable for physical damage, such as cracks on the probe surface and wear or breakage of the cable. Clean the probe surface regularly to remove dust and oil stains that may affect the measurement accuracy. Check the connection between the cable and the proximitor to ensure it is tight. Periodically calibrate the probe using professional calibration equipment to ensure its measurement accuracy. If abnormal signals are found during use, first check the installation position and cable connection. If the problem cannot be solved, contact BENTLY NEVADA’s technical support.
