Product introduction

The 1900/65A-01-02-01-00-00 from Bently Nevada is a compact yet powerful machinery protection monitor designed for industrial environments requiring reliable monitoring of rotating equipment. As part of the 1900 series, this 2-channel monitor serves as a flexible solution for applications where space is constrained but comprehensive machinery protection is still essential. Unlike larger rack-mounted systems, this panel-mount monitor combines measurement capabilities with alarm functionality in a streamlined package, making it suitable for both standalone installations and integration with larger monitoring networks.

Bently Nevada’s 1900/65A-01-02-01-00-00 is engineered to bridge the gap between basic sensors and protection actions, converting raw input signals from proximity probes, accelerometers, and process transmitters into actionable machinery health data. It provides essential protection through configurable alarms while offering sufficient measurement precision for diagnostic trending. This versatility makes it ideal for monitoring pumps, fans, motors, and other rotating machinery in industries ranging from manufacturing to oil and gas, where reliable equipment operation is critical to production continuity.

Core advantages and technical highlights

Dual-channel versatility: The 1900/65A-01-02-01-00-00 features two independently configurable channels that support multiple input types, including proximity probes for vibration and position measurement, accelerometers for vibration monitoring, and 4-20 mA signals for process parameters. This flexibility allows the monitor to adapt to diverse machinery monitoring requirements without requiring specialized hardware for each measurement type.

Rugged design for harsh environments: Built to withstand extreme industrial conditions, the monitor operates reliably across a -20°C to +70°C temperature range and resists the effects of vibration, electromagnetic interference, and moisture. This ruggedization ensures consistent performance in challenging environments such as industrial plants, offshore platforms, and mobile equipment applications.

Simplified integration: The monitor supports both standalone operation and integration with larger monitoring systems through standard communication protocols. Its compact form factor allows installation in space-constrained locations, while compatibility with 3500 series peripherals enables seamless data sharing with enterprise-level maintenance systems when needed.

Configurable protection logic: Each channel offers dual alarm levels (Alert and Danger) with adjustable time delays and latching options, allowing customization of protection strategies to match specific machinery requirements. This flexibility ensures appropriate response to abnormal conditions, from simple alarms to automatic shutdown sequences, helping prevent equipment damage while minimizing unnecessary production interruptions.

Typical application scenarios

Manufacturing facilities

In manufacturing environments, 1900/65A-01-02-01-00-00 monitors are installed on production line motors and gearboxes to track vibration levels and bearing temperatures. The dual channels allow simultaneous monitoring of drive-end and non-drive-end bearings, providing early warning of potential failures. When integrated with plant control systems, these monitors can trigger maintenance alerts or production slowdowns before catastrophic failures occur, reducing unplanned downtime.

Oil and gas pumping stations

Remote pumping stations utilize 1900/65A-01-02-01-00-00 monitors to track vibration and pressure parameters in critical pump assemblies. The monitor’s rugged design withstands the harsh environmental conditions typical of these locations, while its low power consumption makes it suitable for installations with limited power availability. Alarm outputs can activate local indicators or transmit alerts to central control rooms, ensuring timely response to abnormal conditions in these often-unmanned facilities.

Water and wastewater treatment plants

In water treatment facilities, the monitor protects critical rotating equipment such as centrifugal pumps and aeration blowers. It monitors vibration levels and seal water pressure, providing early detection of impeller wear, bearing degradation, or cavitation issues. The panel-mount design simplifies installation in control cabinets, while the wide operating temperature range ensures reliable performance in the varying conditions of treatment plant environments.

Installation, commissioning and maintenance instructions

Installation

Mount the 1900/65A-01-02-01-00-00 on a panel or DIN rail in a location with adequate ventilation and protection from direct moisture. Ensure proper grounding to minimize electrical interference. Connect sensors using shielded cables (such as 136711-01) to the appropriate input terminals, following polarity markings. Wire alarm outputs to control devices or indicators, ensuring compliance with local electrical codes. Apply 18-32 VDC power using a regulated power supply, preferably with surge protection.

Commissioning

After installation, configure the monitor using compatible software via USB connection (using cables like 123M4610 for interface modules). Set input types, measurement ranges, and alarm thresholds for each channel based on machinery specifications. Verify sensor connections by applying test signals or observing normal operation values. Test alarm functionality by simulating abnormal conditions to ensure proper activation of outputs and indicators. Document configuration settings for future reference.

Maintenance

Perform quarterly visual inspections to check for loose connections, corrosion, or physical damage. Verify power supply integrity and ensure ventilation paths remain unobstructed. Calibrate the monitor annually using certified test equipment to maintain measurement accuracy. Download and archive trend data periodically to support predictive maintenance efforts. During maintenance, check alarm response times and verify that configuration settings remain unchanged from approved baselines. Replace any damaged cables or connectors promptly to ensure reliable operation.
