Product Introduction
The 1900/55 is an industrial monitoring module developed by Bently Nevada, a globally leading supplier of industrial vibration monitoring and equipment protection systems (now a brand under Baker Hughes). This series of products is mainly used for monitoring fans and general equipment status. It is designed to continuously monitor the vibration status and dynamic behavior of rotating machinery, especially low-frequency equipment such as fans, providing real-time data support for maintenance, fault prediction, and equipment protection.

Product Details
Bently Nevada has been dedicated to the research and development of vibration and rotating machinery health monitoring equipment since the 1960s, and has accumulated a large amount of application experience in industries such as power, petrochemical, and manufacturing. The 1900/55 series products belong to one of the 1900 series of Bently Nevada, and are mainly used for continuous monitoring applications in industrial sites.
1900/55-01-01-01-00 is designed as an industrial-level, real-time vibration and condition monitoring module that can operate independently or be integrated with the on-site control system. Its core purpose is:
-- To provide continuous monitoring of the mechanical operation status;
-- To determine whether there are potential faults such as imbalance, loosening, or abnormal bearings in the equipment by analyzing signals such as vibration and speed;
-- To support alarm, online control, and predictive maintenance.
Unlike some monitoring devices that are only applicable to high-speed turbines, 1900/55 is more suitable for the condition monitoring of low-speed mechanical equipment such as fans, pumps, and blowers, especially in scenarios where long-term online monitoring is required.
1900/55 Core Function and Monitoring Capabilities
The main functions of 1900/55 are focused on vibration monitoring for industrial fans and general rotating equipment. Its design is adapted to the harsh environment of factory sites. Common features include:
Multi-channel vibration monitoring system
Supports multi-channel configuration, capable of simultaneously receiving vibration signals from multiple sensors;
Performs independent real-time monitoring for different locations (such as bearing housings, gearboxes, etc.); Vibration monitoring covers a range from low frequency to high frequency (such as 1.5 – 1000 Hz ±3 dB frequency response).
Real-time warning and alarm capabilities
The system can conduct dynamic analysis on the input signal.
When the vibration value exceeds the set threshold, an immediate alarm and protection action will be triggered.
Parameters such as time delay and alarm relay type can be configured. It can be linked with the control system to achieve automatic and safe shutdown.
Local or networked monitoring support
An optional communication module (such as Modbus RTU and other protocols) can be connected to DCS/PLC or monitoring software.
Utilize the Modbus protocol to transmit monitoring data to the management system, enabling long-term trend analysis. It can be seamlessly integrated with Baker Hughes' System 1 software to optimize equipment health management.
Configurable parameters and flexible settings
Parameters such as time delay setting, relay logic selection, and scan time configuration can be set through the front panel or the communication interface.
Support on-site adjustment, without the need for switch or jumper wire settings.
Remarkable Service
Installation location determined:
Main monitoring unit location
Installed in a position that is convenient for observation and maintenance;
If installed in the control cabinet, ensure that the control cabinet has good ventilation. If installed outdoors, it is recommended to use a waterproof and dust-proof chassis or protective enclosure to safeguard the equipment.
Installation method
The Bently Nevada 1900 series monitoring module offers multiple installation options:
Panel installation
DIN rail installation
Installation of cabinet fixing bolts
These methods support various on-site layouts, such as control cabinets, wall surfaces of the machine room, brackets, etc.
Parameter setting
After the installation is completed, the engineer should enter the monitoring module to make the necessary configurations, such as:
Channel type setting (speed/vibration);
Alarm threshold setting (Alert/Danger);
Logical parameters like time delay, Scan cycle, etc
