BENTLY 3500/33-01-00

Description

1. Parameter Specifications

• Power Supply: The BENTLY 3500/33 – 01 – 00 operates on a 24V DC power supply. It has a relatively low power consumption, typically around 10 – 15W, which is suitable for long – term continuous operation in industrial environments.
• Input Signals: It is designed to receive signals from various types of sensors. It can interface with proximity probes to measure shaft displacement, vibration sensors for vibration monitoring, and temperature sensors. The input impedance is carefully calibrated to ensure accurate signal reception, usually in the range of several kilo – ohms depending on the sensor type.
• Output Signals: The module provides analog and digital output signals. The analog outputs are commonly in the 4 – 20mA or 0 – 10V range, which can be used to transmit measurement data to other control systems such as distributed control systems (DCS) or programmable logic controllers (PLC). Digital outputs are used for alarm signaling and status indication, and they may communicate via protocols like Modbus RTU or Profibus DP.
• Measurement Range: For shaft displacement measurement, it can typically cover a range of ±250μm to ±1000μm, depending on the specific probe used. For vibration measurement, it can measure vibration amplitudes in the range of 0 – 25mm/s (peak – to – peak).

2. Applications

• Rotating Machinery Monitoring: In power plants, the BENTLY 3500/33 – 01 – 00 is used to monitor the condition of steam turbines, generators, and gas turbines. It continuously measures shaft displacement, vibration, and temperature to detect early signs of misalignment, imbalance, or bearing wear.
• Petrochemical Industry: In refineries and chemical plants, it monitors the operation of pumps, compressors, and fans. By analyzing the vibration and displacement data, it helps prevent equipment failures and unplanned shutdowns, ensuring the safety and efficiency of the production process.
• Manufacturing Industry: In large – scale manufacturing facilities, it is used to monitor the condition 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 3500/33 – 01 – 00 weighs approximately 1.2 kg. Its relatively light weight makes it easy to install and handle during the setup and maintenance processes.
• Dimensions: It has dimensions of around 200 mm in length, 150 mm in width, and 80 mm in height. These compact dimensions allow it to be easily installed in standard industrial control cabinets.

4. Features

• High – Precision Monitoring: It offers high – precision measurement capabilities, with a resolution of up to 0.1μm for displacement measurements and high – accuracy vibration measurement. This allows for the detection of even the smallest changes in machinery conditions.
• Multifunctional Sensing: The module can handle multiple sensor inputs simultaneously, providing a comprehensive view of the machinery’s health. It can monitor different parameters such as displacement, vibration, and temperature at the same time.
• User – Friendly Interface: It comes with an intuitive interface that allows operators and technicians to easily configure the device, view real – time data, and set alarm thresholds according to their specific requirements.

5. Stability and Reliability

• Robust Construction: The module is built with high – quality materials and a sturdy housing that can withstand harsh industrial environments, including high temperatures, humidity, and mechanical vibrations.
• Redundancy and Self – Diagnosis: Some versions may have redundant components and self – diagnostic features. In case of a component failure, the redundant parts can take over, ensuring continuous operation. The self – diagnostic function helps in quickly identifying and resolving issues.
• Quality Assurance: BENTLY is known for its strict quality control during manufacturing, guaranteeing long – term reliable performance.

6. Real – World Examples

• Power Generation Plant: In a large – scale coal – fired power plant, the BENTLY 3500/33 – 01 – 00 is used to monitor the steam turbine. By continuously monitoring the shaft displacement and vibration, it detected a slight increase in vibration levels. This early detection allowed the maintenance team to investigate and discover that one of the turbine blades had a small crack. They were able to schedule a maintenance shutdown in advance, preventing a more serious failure that could have led to a long – term power outage.
• Petrochemical Refinery: In an oil refinery, the BENTLY 3500/33 – 01 – 00 was installed on a large compressor. The module detected a sudden change in the shaft displacement, which indicated a possible bearing problem. The refinery was able to stop the compressor immediately, avoiding a major breakdown that could have caused a significant loss of production and potential safety hazards. This proactive maintenance approach saved the refinery both time and money.
