BENTLY 125800-01

Description

1. Parameter Specifications

• Power Supply: The BENTLY 125800 – 01 typically operates on a 24V DC power supply. The power consumption is relatively low, around 5 – 8W, which is energy – efficient for continuous operation in industrial settings.
• Measurement Capabilities:
  • Displacement Measurement: It is mainly designed for accurate displacement measurement. It can measure shaft displacement with a high resolution, usually up to 0.1μm. The measurement range can be adjusted according to the specific application, typically covering ±250μm to ±1000μm.
  • Frequency Response: It has a wide frequency response range, which can accurately measure the dynamic displacement changes of the shaft. The frequency response can reach up to several kHz, enabling it to capture high – frequency vibration components.
• Output Signals:
  • Analog Output: It provides an analog output signal, usually in the range of 4 – 20mA or 0 – 10V. This analog signal is proportional to the measured displacement, which can be easily connected to other control systems such as distributed control systems (DCS) or programmable logic controllers (PLC) for further processing and monitoring.
  • Digital Output: It may also have digital output interfaces for alarm signaling and status indication. These digital outputs can communicate with other devices via protocols like Modbus RTU.
• Accuracy: The measurement accuracy is high, typically within ±0.5% of the full – scale measurement range. This high accuracy ensures reliable monitoring of shaft displacement in industrial machinery.

2. Applications

• Rotating Machinery Monitoring: In power plants, the BENTLY 125800 – 01 is widely used to monitor the shaft displacement of steam turbines, generators, and gas turbines. By continuously measuring the shaft displacement, it can detect early signs of misalignment, imbalance, or bearing wear. For example, if the shaft displacement exceeds the normal range, it may indicate a problem with the bearing, and timely maintenance can be carried out to prevent more serious damage.
• Petrochemical Industry: In refineries and chemical plants, it is used to monitor the shaft displacement of pumps, compressors, and fans. These rotating machines are crucial for the production process, and any abnormal shaft displacement can lead to equipment failure and production interruption. The BENTLY 125800 – 01 can help ensure the stable operation of these machines.
• Manufacturing Industry: In large – scale manufacturing facilities, it is used to monitor the shaft displacement of high – speed rotating machinery such as lathes, milling machines, and grinding machines. This helps in maintaining product quality and reducing downtime due to equipment breakdowns.

3. Weight and Dimensions

• Weight: The BENTLY 125800 – 01 weighs approximately 0.8 kg. Its relatively light weight makes it easy to install and handle during the setup and maintenance processes.
• Dimensions: It has compact dimensions, typically around 150 mm in length, 100 mm in width, and 50 mm in height. These dimensions allow it to be easily installed in standard industrial control cabinets or on DIN rails.

4. Features

• High – Precision Measurement: With its high – resolution and high – accuracy measurement capabilities, it can provide precise displacement measurement data, which is crucial for early fault detection in rotating machinery.
• Wide Frequency Response: The wide frequency response range enables it to capture both low – frequency and high – frequency displacement changes, providing a comprehensive view of the shaft’s dynamic behavior.
• Easy Integration: The analog and digital output interfaces make it easy to integrate with other control and monitoring systems, facilitating seamless data transfer and system – level control.

5. Stability and Reliability

• Robust Construction: The BENTLY 125800 – 01 is built with a sturdy housing that can withstand harsh industrial environments, including high temperatures, humidity, and mechanical vibrations.
• Quality Components: It uses high – quality electronic components that are selected for their reliability and long – term performance. This helps to ensure stable operation over an extended period.
• Self – Diagnostic Function: It has a self – diagnostic function that can detect internal faults and abnormal operating conditions. The diagnostic information can be used for quick troubleshooting and maintenance, reducing the downtime of the monitoring system.

6. Real – World Examples

• Power Plant Turbine Monitoring: In a large – scale coal – fired power plant, the BENTLY 125800 – 01 is installed on the steam turbine. One day, the monitoring system detected a gradual increase in the shaft displacement. The maintenance team was immediately alerted, and after further inspection, they found that the turbine’s bearing had started to wear. Thanks to the early detection by the BENTLY 125800 – 01, the bearing was replaced in time, preventing a major turbine failure and avoiding a long – term power outage.
• Petrochemical Compressor Monitoring: In a petrochemical refinery, the BENTLY 125800 – 01 is used to monitor the shaft displacement of a large compressor. During normal operation, the measured displacement was within the normal range. However, one day, the system suddenly detected a significant increase in displacement. The compressor was immediately shut down for inspection, and it was found that a coupling had become loose. The timely detection by the BENTLY 125800 – 01 prevented a potential compressor explosion and ensured the safety of the refinery.
