Features

Multi-Channel Flexibility

8 independent channels support simultaneous monitoring of multiple process parameters, allowing integration of diverse sensors (e.g., pressure transducers, thermocouples, flow meters) into the 3500 system.

High Accuracy and Isolation

±0.1% full-scale accuracy ensures precise measurement of critical process variables, while 2500 VAC isolation protects against electrical noise and ground loops in industrial environments.

Wide Sensor Compatibility

Supports 4–20 mA, 0–10 VDC, and RTD inputs, adapting to common industrial sensor types and enabling flexibility in system configuration.

Rugged Industrial Design

Robust construction resists vibration, electromagnetic interference (EMI), and temperature fluctuations, ensuring reliable performance in harsh settings like refineries and power plants.

Seamless System Integration

Connects to the 3500 system backplane to share data with monitoring modules and communication gateways, enabling centralized analysis and integration with SCADA/DCS systems.

Function

The primary function of the 106M1081-01 is to collect, condition, and convert analog signals from external sensors into digital data for the Bently Nevada 3500 system. It receives signals from sensors measuring process parameters (e.g., pressure in pipelines, temperature in bearings, flow in process lines), filters out noise, and amplifies weak signals to ensure accuracy. The module then converts these analog signals to digital values, which are transmitted to the 3500 system controller for analysis. By integrating process data with vibration and position monitoring, it enables the 3500 system to correlate machinery health with operational conditions, supporting comprehensive fault detection and preventive maintenance.

Use

In industrial settings, the module is installed in the 3500 system rack, where it connects to external sensors via shielded cables. It interfaces with pressure transducers on pumps, thermocouples on motors, and flow meters in pipelines, converting their signals into actionable data. Operators configure the module using 3500 system software to set input types, scaling, and alarm thresholds for each channel. The processed data is displayed on the 3500 HMI or integrated into SCADA/DCS systems, allowing operators to monitor process conditions alongside machinery health metrics.

Application Fields

Power Generation

Monitors boiler pressure, steam temperature, and feedwater flow in thermal power plants, integrating process data with turbine vibration monitoring to ensure efficient and safe electricity production.

Oil and Gas

Measures pipeline pressure, fluid flow, and separator levels in upstream and midstream operations, enabling correlation of process conditions with compressor and pump health to prevent overloads.

Chemical Processing

Tracks reactor temperature, agitator speed, and chemical flow rates, supporting safe operation by linking process parameters to mixer and pump vibration data.

Pulp and Paper

Monitors paper machine web tension, roll pressure, and drying cylinder temperature, optimizing production by integrating process data with machinery condition metrics.

Mining and Metals

Measures hydraulic pressure in crushers, conveyor belt load, and coolant flow in mills, ensuring equipment reliability by correlating process loads with machinery vibration.

In summary, the Bently Nevada 106M1081-01 is a vital analog input module that enhances the 3500 system’s ability to monitor both machinery health and process parameters. Its accuracy, flexibility, and rugged design make it essential for industries seeking comprehensive condition monitoring solutions to improve operational efficiency and protect critical assets.
