1. Specification

Input Signal Type: Bently Nevada 330709-000-070-10-02-00 accepts the signal from the probe, processes it, and converts it to enable accurate measurement of related physical quantities, with the specific input signal type, being the matched probe, usually expected to be a high-frequency alternating current signal, which effectively detects small displacement and vibration changes.

Operating Temperature Range: 0°C to +55°C, with a storage temperature of -51°C to +155°C.

Power Consumption: Typical power consumption is 5.02 watts.

Humidity: 95%, non-condensing.

Measurement Range: On the displacement measurement side, Bently 330709-000-070-10-02-00 has a large measurement range. Based on the specific configuration and application requirements, the instrument may measure displacements starting from a few microns and going to several millimeters, and thus meet the requirements for shaft displacement monitoring in most industrial equipment. In the case of vibration measurement, the frequency range falls from DC to several kHz, and thus is able to pick up various vibration frequency components during the operation of the equipment and present rich information for the fault diagnosis.

2. Feature

Integration of Different Measurements: Bently Nevada 330709-000-070-10-02-00 can measure multiple physical quantities of shaft displacement, vibration and key phase simultaneously. Through one device, multi-dimensional information of the equipment's working condition can be obtained, which provides for a better understanding of the health condition of the equipment. For instance, monitoring of a turbine shaft system: In this case, Bently 330709-000-070-10-02-00 can simultaneously monitor radial displacement, axial displacement and vibration of the shaft, and in combination with key phase signal, accurately determines the rotation location and phase relationship of the shaft so as to better analyze the cause of equipment failure.

Real-Time Monitoring and Data Update: Bently Nevada 330709-000-070-10-02-00 features real-time monitoring that enables rapid and continuous collection and processing of data, along with timely updating of results, so that the user knows the latest operational status for the equipment. At the time, during operation, on any occurrence of abnormality, such as marred shaft vibration or displacement beyond the normal range, then, this equipment gets to legitimately wake an alarm and at that very moment alert personnel for preventive action to be undertaken to avert equipment failure.  

3. Application

Power Industry:

Hydropower Generating Units: There are great instances that the hydropower stations owe much to Bently 330709-000-070-10-02-00 in regard to the turbine shaft systems of large hydropower stations for the rightful provision of accurate monitoring on them, such as due to water flow and changes in load. The indication of the shaft displacement across the normal range suggests that bearing wear or shaft misalignment problems can occur. This will give the staff a chance to make adjustments and repairs on time and ensure the safe and efficient operation of the turbine generator set, thereby improving power generation efficiency.

Petrochemical Industry

Centrifugal compressor: In petrochemical production, centrifugal compressors are used to transport several gases. Bently Nevada 330709-000-070-10-02-00 can detect the vibration and displacement of the compressor shaft. During the operation of the centrifugal compressor in the catalytic cracking unit of the refinery, real-time measurements were made by the sensor, indicating a slight increase in vibration of the shaft. Following investigations, the impeller was found to be corroded. With timely impeller replacement, compressor shutdown due to failure was avoided, ensuring normal production for the whole catalytic cracking unit and reducing economic losses caused by equipment failure.

Pump was used with: Voting across numerous pumps in the petrochemical industry, within centrifugal and reciprocating pumps, are conditions that have shaft operating conditions critical for the production process. Bently Nevada 330709-000-070-10-02-00 can monitor the vibration, displacement, and key phase of the pump shaft in real-time. For instance, once, in a chemical plant, a large centrifugal pump made abnormal noise during operation. Bently 330709-000-070-10-02-00 sensed a slight change in the vibration spectrum from the pump shaft. After examination, it was determined that one of the bearings was damaged. With timely replacement of the bearing, the pump came back to operation, ensuring normal transportation of materials in chemical production.

Aerospace field:

Aircraft engine maintenance and inspection: In the maintenance workshop of the aircraft engines, this sensor can be used to inspect the repaired engine. When the airline was testing the repaired engine, Bently Nevada 330709-000-070-10-02-00 showed that the engine's shaft vibration was slightly above the standard value. Further inspections concluded that there was a slight deviation in the position of a component during the installation process. A timely adjustment thereafter enabled it to pass the inspections, certifying the engine quality maintenance and ensuring flight safety.
