BENTLY 3500/61 Process Variable Module
Product Overview: BENTLY 3500/61
The BENTLY 3500/61 process variable module is a high-precision industrial component designed for real-time monitoring of critical process parameters within Bently Nevada’s 3500 Series Machinery Health Monitoring System. As a versatile module in this advanced platform, the 3500/61 interfaces with sensors measuring temperature, pressure, flow, and level, converting analog signals into digital data for comprehensive machinery diagnostics. Engineered for reliability in harsh industrial environments, this module serves as a bridge between field instruments and supervisory control systems, enabling proactive maintenance and process optimization.
Featuring four isolated analog input channels, the 3500/61 supports multiple signal types (4–20 mA, 0–10 V DC, thermocouples, RTDs), ensuring compatibility with diverse sensors. Its 16-bit analog-to-digital conversion ensures high-resolution measurements, while built-in linearization and scaling functions simplify data interpretation. The module’s dual redundant communication paths (Modbus RTU/TCP) enable seamless integration with distributed control systems (DCS) and supervisory control and data acquisition (SCADA) platforms, making it an essential component for industries requiring precise process monitoring.
In automation ecosystems, the 3500/61 enhances system intelligence by combining process variables with mechanical health data from other 3500 Series modules (e.g., vibration monitors). Its -40°C to +85°C operating range and IP20 protection rating ensure durability in demanding settings, from power plant turbines to offshore compressors. By providing real-time insights into process conditions, the module helps operators identify anomalies early, reducing unplanned downtime and optimizing operational efficiency.
