Bently Nevada 330750-60

1. Specification

The maximum cable length:  be extended to 305 meters, no signal attenuation is detected with respect to the determined length;

Sensitivity: typically less than 5% of the static sensitivity, or about ±2% at 152mm/s; installation resonance frequency is suitable for actions below 5kHz; with a general sensitivity measure at 145 mv/in/s (5.7 mv/mm/s).

2. Feature

The employment of non-contact measurement technology: this non-contact type certainly uses free contact acquisition that eliminates any contact between the DOI of traditional measurement due to wear and poor contact problems. The reliability and stability of the measurement are higher than in traditional devices, finding a good compromise to enhance the sensor life while lowering maintenance costs.

Multi-directional monitoring：Bently Nevada 330750-60 allows monitoring of several physical quantities such as shaft displacement, vibration amplitude, frequency, and speed at the same time, to achieve a comprehensive monitoring of rotating machines. The operation condition can be determined very much more accurately through bringing together all the parameters, to detect potential problems like imbalance and misalignment along with shaft cracking, thus establish a ground for maintenance systems management by avoiding blackout or outages caused by failing of equipment while safeguarding the operational stability of the power system.

3. Application

The power industry：comprises monitoring shaft vibration, displacement, and speed; large rotating equipment includes generators, steam turbines, and fans. A real-time monitoring of operating conditions for these machines assures potential hazards of fault faults of power disconnections causing problems like imbalance, misalignment, breakage, etc.

Chemical industrial area: thus at refineries, other chemical plants, and sites; Bently Nevada 330750-60 is used for monitoring several manifold reciprocating machinery such as centrifugal pumps and compressors. Operations and failures such as surge and impeller wear initiation are monitored as observed through Bently 330750-60. To enhance safety and ensure the continuing realization of the production process happens without accidents such as leaks, explosions, or equipment failures. All have optimized effectiveness in the operating parameters and maximized product quality.

Steel industry: During the steel production process, the Bently Nevada 330750-60 online monitor may be used to check the operation of key equipment such as a rolling mill or continuous casting machine. By monitoring the vibration of the rolling mill roll shaft, the rolling parameters can be adjusted in time to prolong roll life and improve steel rolling quality. Vibration monitoring of the continuous casting machine's crystallizer guarantees quality in the ingot and assurance that production proceeds smoothly.

Cement industry: Equipment like a ball mill and rotary kilns are large-scale rotating machinery in the cement industry, and the Bently 330750-60 can be effectively used to monitor them. The Bently Nevada 330750-60 will monitor the shaft vibration and speed of the ball mill, analyze the governing state of the grinding body, optimize the grinding process, and enhance ball mill productivity and cement fineness. The rotary kiln monitoring can enhance its stability and avoid problems, such as cylinder deformation and roller wear, from affecting the quality and output of cement products.

Papermaking industry: The Bently Nevada 330750-60 plays a very significant role in the vibration monitoring of the shafts of various running parts of the papermaking machines, including drying cylinders and press rolls. The abnormal vibration detection of the equipment via the Bently 330750-60 is preemptive and assures no quality problems regarding thickness variations or wrinkling of paper. This quickly enhances quality and efficiency in paper-making and cuts down on maintenance costs and downtime.
