Product Description

The 1900/65A 172323-01 is a General Purpose Equipment Monitor from Bently Nevada, a global leader in condition monitoring and asset protection solutions. This versatile and cost-effective monitor is engineered to continuously assess the health of a wide range of industrial machinery. It acquires and processes critical data related to vibration, position, speed, and temperature, providing real-time insights and robust protection capabilities. This makes it an ideal solution for general-purpose machines across various industries where continuous monitoring and early fault detection are crucial for maintaining operational efficiency, reliability, and safety.

Application Scenarios

Consider a large industrial facility with numerous ancillary equipment, such as cooling tower fans, air compressors, and small to medium-sized pumps, which are vital for plant operations but not considered “critical” enough for complex protection systems. Unexpected failures of these machines can still lead to significant downtime and production losses. A chemical processing plant faced such issues with recurring bearing failures in their agitator motors, leading to unexpected stoppages. By deploying the Bently Nevada 1900/65A 172323-01 monitors on these agitator motors, they gained continuous visibility into their vibration signatures. The 1900/65A 172323-01 precisely detected increasing vibration levels, triggering “Alert” warnings when vibration exceeded preset thresholds. This allowed the maintenance team to schedule preventive maintenance during planned outages, replacing the worn bearings before they failed catastrophically. This proactive approach, enabled by the 1900/65A 172323-01, addressed the plant’s pain points of unscheduled downtime and reactive maintenance, leading to improved operational predictability and reduced repair costs.

Technical Principles and Innovative Values

The 1900/65A 172323-01 incorporates fundamental principles of condition monitoring with several key innovative aspects:

• Innovation Point 1: Integrated Multi-Parameter Data Acquisition and Advanced Signal Processing: The 1900/65A 172323-01 is capable of simultaneously acquiring data from various types of sensors – vibration (acceleration, velocity, proximity), position, speed, and temperature – through its 4 transducer and 4 temperature inputs. Each channel features a 24-bit Analog-to-Digital Converter (ADC) for high-resolution data capture. Crucially, it processes up to four distinct variables per channel continuously (e.g., direct amplitude, gap voltage, filtered vibration, and enveloping for bearing fault detection). This integrated, multi-parameter approach and advanced signal processing allow for comprehensive machine health assessment and early detection of a wide array of developing faults, offering a significant advantage over simpler, single-parameter monitors.
• Innovation Point 2: Configurable Alarm Logic and Flexible Output Options: The monitor provides independent “Alert” and “Danger” setpoints for each monitored parameter, ensuring timely warnings. Its six programmable relay outputs can be customized to trigger based on any channel’s status or a combination of statuses, enabling automated shutdowns or external alarms. Furthermore, four configurable 4-20 mA analog outputs provide continuous trending data to Distributed Control Systems (DCS) or SCADA systems. This intelligent alarm management system and versatile output capabilities facilitate rapid, automated responses to escalating machine issues, minimizing human intervention and preventing catastrophic equipment damage.
• Innovation Point 3: Standalone Operation with Robust Communication and Data Integration: The 1900/65A 172323-01 can function as a standalone unit, especially when paired with its optional local display/keypad for direct monitoring and minor configuration. For integration into broader plant networks, it supports Modbus TCP/IP over Ethernet and an RS232/RS485 serial port. This robust communication suite allows it to transmit real-time data, alarm statuses, and historical event lists to higher-level control systems (PLCs, DCSs, SCADA) or Bently Nevada’s System 1® software. This ensures seamless data integration, enabling both localized machine protection and enterprise-wide asset performance management without requiring complex middleware.

Application Cases and Industry Value

In a manufacturing facility, the critical air compressors were prone to unexpected vibrations, leading to premature wear and unplanned maintenance. The existing monitoring system was basic and didn’t provide sufficient early warning. By installing Bently Nevada 1900/65A 172323-01 monitors on their compressors, the facility gained continuous, high-fidelity vibration data. The monitors’ advanced signal processing detected subtle increases in vibration levels, indicating developing bearing issues weeks in advance. The “Alert” relay outputs were connected to the plant’s maintenance system, automatically generating work orders when specific vibration thresholds were exceeded. This allowed the maintenance team to schedule repairs during routine downtimes, avoiding costly emergency shutdowns and extending the lifespan of the compressors. This application directly contributed to a 20% reduction in maintenance costs and a significant improvement in overall equipment effectiveness (OEE), demonstrating the Bently Nevada 1900/65A 172323-01‘s strong value proposition for predictive maintenance in general-purpose machinery.
