Bently Nevada 3500/62 133811-03 Process Variable Monitor

Product Introduction

The Bently Nevada 3500/62 133811-03 Process Variable Monitor is a specialized monitoring module in the Bently Nevada 3500 Machinery Protection System. It is designed to interface with process variable signals such as pressure, flow, level, or temperature from industrial transmitters. By bringing process data into the same rack system that monitors machinery parameters like vibration and position, the 3500/62 allows engineers to view both machinery and process conditions in a unified platform.

This monitor accepts standard 4–20 mA signals and provides electrical isolation, scaling, alarming, and integration with the rack’s display and communication modules. The 3500/62 enhances plant reliability by enabling correlation of machinery health with process conditions, supporting both protection and predictive maintenance strategies.

Product Applications

The 3500/62 133811-03 Process Variable Monitor extends the monitoring capabilities of the 3500 rack by including critical process signals. Common applications include:

• Turbomachinery Systems – Integrating process conditions (such as lube oil pressure, fuel gas pressure, or cooling water flow) with vibration and temperature monitoring.

• Compressors and Pumps – Monitoring suction/discharge pressures, flow rates, and bearing lube oil temperatures.

• Generators and Motors – Correlating process parameters with electrical load and mechanical behavior.

• Petrochemical and Refinery Plants – Supervising process-critical variables for plant protection.

• Power Plants – Monitoring cooling water systems, steam pressures, and process feed rates.

• Oil & Gas Facilities – Offshore and onshore process safety monitoring with machinery protection.

Product Advantages

• Unified Monitoring: Brings process variables and machinery data together in a single system.

• Flexible Inputs: Accepts standard 4–20 mA transmitter signals from multiple process instruments.

• High Accuracy: Ensures reliable process variable measurement for protection and diagnostics.

• Scalable: Four independent channels per module reduce the need for multiple devices.

• Real-Time Protection: Fast sampling ensures timely alarm response to abnormal conditions.

• System Integration: Works seamlessly with Bently Nevada 3500 rack displays and communication modules.

• Built-In Diagnostics: Detects signal loss, wiring faults, and module issues proactively.

• Proven Reliability: Industrial-grade design tested for continuous operation in demanding environments.
