Bently Nevada 1900/65A General Purpose Equipment Monitor
The Bently Nevada 1900/65A General Purpose Equipment Monitor is designed to continuously monitor and protect equipment that is used in a variety of applications and industries. The monitor's low cost makes it an ideal solution for general-purpose machines and processes that can benefit from continuous monitoring and protection.
The 1900/65A provides four transducer inputs and four temperature inputs. Software can configure each transducer input to support 2- and 3-wire accelerometers, velocity sensors or proximity sensors. Each temperature input supports Type E, J, K, and T thermocouples, and 2- or 3-wire RTDs.
The 1900/65A provides six relay outputs, four 4-20 mA recorder outputs, and a dedicated buffered output. The user can use the 1900 Configuration software to configure the relay contacts to open or close according to the OK, Alert and Danger statuses of any channel or combination of channels, and to provide data from any variable from any channel on any recorder output. The dedicated buffer output can provide the signal for each transducer input.
A Modbus® Gateway option allows the monitor to provide static variables, statuses, event list, time and date information directly to any Modbus client, including Distributed Control Systems (DCSs), Supervisory Control and Data Acquisition (SCADA) systems, Programmable Logic Controllers (PLCs), or System 1® software. The monitor uses an internal counter and a Modbus client/master time reference to generate time and date information. Users can upgrade monitors without the Modbus Gateway by ordering the 1900/01 Communications Upgrade (see the Ordering Information section). The 1900/65A supports Modbus communications via Ethernet and a software-configurable RS232/485 serial port.
The user defines monitor operation and the Modbus Gateway register map by using software running on a laptop or PC to create a configuration file and download the file to the monitor through the built-in Ethernet connection. The 1900/65A permanently stores configuration information in non-volatile memory, and can upload this information to the PC for changes.
The 1900/65A supports an optional display/keypad to view channel information or make minor configuration changes. This allows the 1900/65A to operate as a stand-alone package. If desired, the user can mount the display up to 75 metres (250 feet) from the Monitor Module.
The Bently Nevada 1900/65A General Purpose Equipment Monitor is a remarkable and versatile device that has long been trusted in the industrial machinery monitoring landscape.
The 1900/65A is a highly capable monitor specifically engineered to cater to a wide array of general-purpose equipment monitoring needs. It serves as a crucial tool for ensuring the reliable operation of industrial machinery by providing accurate and timely information about the equipment's condition.
- Input Flexibility: This monitor can accept a variety of input signals. It is compatible with both proximity probes and velocity transducers, allowing it to measure different parameters such as shaft vibration, axial position, and machine velocity. For proximity probe inputs, it has an input impedance of 10 kΩ, ensuring stable signal reception.
- Signal Conditioning: It comes with built-in signal conditioning capabilities. The 1900/65A can filter and process the incoming signals to extract meaningful data. It offers options for low-pass, high-pass, and band-pass filtering, enabling users to customize the signal processing according to their specific requirements.
- Display and Indicators: The front panel of the 1900/65A features a clear and intuitive display. It shows the measured values of the monitored parameters in real-time. Additionally, there are status indicators such as OK, ALERT, and DANGER LEDs. These LEDs provide quick visual cues about the equipment's condition, making it easy for operators to identify potential issues at a glance.
- Alarm Configuration: Users can configure alarm setpoints for each monitored parameter. The monitor continuously compares the measured values against these setpoints and triggers alarms when the limits are exceeded. This proactive approach helps prevent equipment failures and minimizes downtime.
- Comprehensive Monitoring: The 1900/65A is capable of monitoring multiple parameters simultaneously. Whether it's tracking the vibration levels of a rotating machine or monitoring the axial movement of a shaft, this monitor provides a holistic view of the equipment's performance.
- Data Logging and Analysis: It has the ability to log historical data, which can be invaluable for trend analysis. By analyzing the logged data, maintenance personnel can identify patterns and predict potential equipment failures before they occur. This allows for proactive maintenance planning, reducing the risk of unexpected breakdowns.
- Communication Capabilities: The 1900/65A can communicate with other devices or systems. It supports standard communication protocols such as RS-485, enabling it to integrate with larger industrial control networks. This allows for remote monitoring and control, enhancing the overall efficiency of the monitoring system.
The 1900/65A finds extensive use in various industries. In the manufacturing sector, it is used to monitor the performance of machine tools, ensuring the quality of the production process. In the power generation industry, it plays a vital role in monitoring turbines and generators, helping to maintain their optimal operation. In the oil and gas industry, it is deployed to monitor pumps, compressors, and other critical equipment, safeguarding the integrity of the production and transportation processes.
In conclusion, the Bently Nevada 1900/65A General Purpose Equipment Monitor is a reliable and feature-rich device that has proven its worth in industrial machinery monitoring. Its advanced technical features, comprehensive functionalities, and wide range of applications make it an essential tool for ensuring the safe and efficient operation of industrial equipment.
