Bently Nevada 3500/42M 176449-02 Proximitor/Seismic Monitor

Functional Features Multi-parameter Monitoring: It can accept input signals from proximity sensors and seismic sensors, and is capable of monitoring multiple parameters such as radial vibration, thrust position, differential expansion, eccentricity, acceleration, and velocity. After processing the signals, it compares them with user-programmable alarm values to achieve comprehensive monitoring of the equipment's operating status. Real-time Monitoring and Spectrum Analysis: It can continuously monitor the vibration of the equipment and provide real-time data feedback. At the same time, it supports the spectrum analysis function, which helps to identify fault frequencies and abnormal vibration patterns, making it easier to detect potential faults in a timely manner. Communication Capability: It supports communication protocols such as Modbus and Ethernet/IP, and can communicate with other monitoring systems or data acquisition systems, facilitating data sharing and integration. Status Indication: The front panel is equipped with LED indicator lights, including the OK indicator light (displaying the normal operating status), TX/RX indicator lights (indicating the communication status), etc., which enables operators to quickly understand the working status of the module.

Technical Parameters Input Signals: It can accept signals from 1 to 4 proximity, velocity, or acceleration sensors. In terms of input impedance, the standard I/O is 10kΩ (for proximity and acceleration inputs); for TMR I/O, when three bus TMR I/O channels are connected in parallel to one sensor, the effective impedance is 50kΩ. Sensitivity: The sensitivity of parameters such as radial vibration, thrust, and eccentricity is selectable. For example, the sensitivity of radial vibration can be selected as 3.94 or 7.87mV/µm; the acceleration sensitivity is 10mV/(m/s²); the velocity sensitivity can be selected from 20, 5.8, or 4mV/(m/s), etc. Power Consumption: The typical value is 7.7 watts. Dimensions: Approximately 7.5×3.5×1.5 inches. Weight: Approximately 1kg.

Application Areas: It is widely applied in industrial fields such as power generation, chemical engineering, metallurgy, petroleum, cement, papermaking, and machinery. It is suitable for continuous monitoring of various rotating and reciprocating machinery, such as industrial gas and steam turbines, aeroderivative gas turbines, hydraulic turbines, air or process gas compressors, turboexpanders, electric motors, and generators, etc.

Application Cases of Bently Nevada 3500/42M 176449 - 02: Petrochemical Industry: In large-scale petroleum refineries, the main blower of the catalytic cracking unit is a key piece of equipment. Bently Nevada 3500/42M is used to monitor the vibration of the main blower in real-time. Through the multi-channel monitoring function, it can simultaneously monitor the vibration conditions of multiple bearing points of the blower. Once the vibration value approaches or exceeds the set threshold, the module will promptly trigger an alarm to remind the operators to conduct inspections and maintenance, avoiding blower failures caused by excessive vibration, which in turn affects the entire refining production process.

Power Industry: In thermal power plants, the steam turbine is a key equipment for converting the thermal energy of steam into mechanical energy. The 3500/42M module can accurately monitor parameters such as the shaft vibration and bearing vibration of the steam turbine. For example, through the spectrum analysis function, it can accurately identify abnormal vibration frequencies caused by reasons such as steam turbine blade fouling and shafting imbalance, helping maintenance personnel to formulate maintenance plans in advance and carry out targeted treatment during unit minor repairs or overhauls, ensuring the safe and stable operation of the steam turbine and improving power generation efficiency.

Metallurgical Industry: In the blast furnace blowers of steel plants, the 3500/42M module is applied to monitor their vibration status. When problems such as impeller wear and gear failures occur in the blowers, the module can promptly capture the changes in vibration and transmit the data to the monitoring system in the central control room through the Modbus or Ethernet/IP communication protocol, so that technicians can analyze and deal with it in a timely manner, preventing equipment failures from causing the shutdown of the blast furnace and reducing production losses.

Papermaking Industry: In the transmission systems of large paper machines in paper mills, the 3500/42M module is used to monitor the vibration conditions of equipment such as motors and reducers. Through the real-time monitoring and historical data recording functions, technicians can analyze the changing trends of equipment vibration and discover potential fault hazards in advance, such as bearing wear and poor gear meshing, and reasonably arrange the maintenance time of the equipment to avoid a decline in paper quality or production interruptions caused by equipment failures.
