BENTLY 190501-12-00-CN

Description

1. Product overview

The BENTLY 190501 – 12 – 00 – CN is a specialized Velomitor CT velocity transducer, playing a crucial role in BENTLY’s machinery condition monitoring solutions. It is a low – frequency variant of the standard Velomitor piezo – velocity sensor, meticulously designed to precisely measure the casing vibration velocity of cooling tower and air – cooled heat – exchanger fan assemblies. These assemblies typically operate at speeds of 100 to 300 rpm, with a minimum operational speed of 90 rpm. By accurately measuring the vibration velocity, this transducer provides valuable insights into the health and performance of the monitored equipment, enabling early detection of potential issues and preventing costly breakdowns.

3. Product features and technical highlights

Low – frequency vibration measurement expertise: The 190501 – 12 – 00 – CN is specifically tuned to measure low – frequency vibrations, which are characteristic of cooling tower and air – cooled heat – exchanger fan assemblies. In a large industrial cooling system, these fan assemblies often operate at relatively low speeds, and their vibrations can be challenging to detect accurately. The transducer’s design, with its optimized frequency range, can precisely capture these low – frequency vibrations. By accurately measuring the vibration velocity, it can detect early signs of issues such as fan blade imbalance or bearing wear. For example, a slight imbalance in the fan blades will cause a specific pattern of low – frequency vibrations, which the 190501 – 12 – 00 – CN can detect and transmit as data for further analysis.

High – quality construction for durability: The use of 316L stainless steel for both the case and the connector ensures exceptional durability. In an industrial environment where the transducer may be exposed to harsh weather conditions, corrosive chemicals, or mechanical stress, the 316L stainless – steel construction provides long – term reliability. For instance, in a coastal power plant, where the cooling towers are constantly exposed to salt – laden air, the 190501 – 12 – 00 – CN’s stainless – steel components resist corrosion, ensuring continuous and accurate vibration monitoring.

Reliable connection and long – distance signal transmission: The mil – c 5015 connection interface, along with the long – cable support, enables reliable signal transmission over significant distances. In a large – scale industrial complex, the monitoring equipment may be located in a central control room, while the cooling tower fan assemblies are spread out across the facility. The 190501 – 12 – 00 – CN can maintain a stable connection and transmit accurate vibration data over a cable length of up to 305 m. The splash – proof and isolated design of the connector further enhance the reliability of the connection, protecting against environmental factors that could interfere with signal quality.

Sensitivity and accuracy for early problem detection: With a sensitivity of 3.94 mv/mm/s (100 mv/in/s) ± 5% and a wide frequency response, the transducer can detect even the most minute changes in vibration velocity. This high level of sensitivity and accuracy is crucial for early detection of machinery problems. In an air – cooled heat – exchanger in a chemical plant, a small amount of debris getting stuck on a fan blade can cause a subtle change in vibration velocity. The 190501 – 12 – 00 – CN can detect this change, allowing maintenance personnel to address the issue before it leads to more significant problems, such as increased wear on the bearings or damage to the fan motor.

4. Typical application scenarios

Industrial cooling systems: In industrial plants, cooling towers are essential for maintaining the proper operating temperature of various processes. The 190501 – 12 – 00 – CN is used to monitor the vibration velocity of the fan assemblies in these cooling towers. By continuously measuring the vibration, it can detect any abnormal behavior, such as unbalanced fan blades or misaligned bearings. In a large manufacturing facility, if the vibration levels of a cooling – tower fan exceed the normal range, it could indicate a problem that, if left unaddressed, could lead to reduced cooling efficiency or even fan failure. The data from the transducer can be used to schedule preventive maintenance, ensuring the continuous and efficient operation of the cooling system.

Power generation plants: Power plants, whether they are coal – fired, gas – fired, or nuclear, rely on air – cooled heat – exchangers to dissipate heat. The 190501 – 12 – 00 – CN is installed on the fan assemblies of these heat – exchangers to monitor their vibration velocity. In a gas – fired power plant, the heat – exchanger fan assemblies are crucial for maintaining the proper temperature of the cooling water used in the power – generation process. Any malfunction in these fan assemblies can affect the overall efficiency of the power plant. The transducer can detect early signs of problems, such as fan – motor issues or excessive wear in the speed reducer, allowing for timely maintenance and preventing power – generation disruptions.

HVAC systems in large buildings: In large commercial buildings, such as shopping malls or office complexes, HVAC (Heating, Ventilation, and Air – Conditioning) systems often use air – cooled heat – exchangers. The 190501 – 12 – 00 – CN can be used to monitor the vibration of the fan assemblies in these heat – exchangers. In a large shopping mall, the HVAC system operates continuously to maintain a comfortable indoor environment. Monitoring the vibration of the heat – exchanger fan assemblies using this transducer can help facility managers detect any potential problems, such as bearing wear or fan – blade damage. By addressing these issues promptly, they can ensure the smooth operation of the HVAC system, providing a pleasant environment for customers and employees while minimizing energy consumption.

5. Installation and maintenance guidelines

Installation: Before installation, carefully review the detailed installation manual provided by BENTLY NEVADA. Ensure that the installation area on the machinery is clean and free from any debris or contaminants that could affect the transducer’s performance. When installing the transducer, use the provided – 12 – plate stud (3/8 – in 24 to m8x1) to securely mount it on the casing of the cooling tower or air – cooled heat – exchanger fan assembly. Make sure the mounting is stable and the transducer is properly aligned to accurately measure the vibration. Connect the transducer to the monitoring equipment using the mil – c 5015 connection interface, ensuring that the connection is tight and secure. Route the cable in a way that avoids contact with moving parts, hot surfaces, or areas with high electromagnetic fields.

Maintenance: Regularly inspect the 190501 – 12 – 00 – CN for any signs of physical damage, such as cracks in the casing or loose connections. Clean the transducer surface periodically to remove dust, dirt, and any other contaminants that could accumulate over time, especially in dusty industrial environments. Check the signal transmission quality by comparing the data received at the monitoring unit with the expected values. If there are any issues with the signal, such as weak or erratic readings, first check the connections. If the problem persists, refer to the troubleshooting guide in the manual. In case of a malfunction, contact BENTLY’s technical support team for assistance. Periodically, check for any updates or advisories from BENTLY regarding the transducer to ensure optimal performance.
