Description
BENTLY 3500/60 Six-Channel Temperature Monitoring Module
1. Product Description
The BENTLY 3500/60 is a high-precision, modular temperature monitoring solution designed for industrial applications requiring real-time data analysis and reliable alarm activation. As part of the BENTLY 3500 Series, this six-channel module supports simultaneous monitoring of temperature using Resistance Temperature Detectors (RTDs) or thermocouples (TCs). It offers configurable alarm setpoints, advanced signal conditioning, and seamless integration with BENTLY’s System 1 software for predictive maintenance. The 3500/60 is engineered for harsh environments, making it ideal for power generation, oil & gas, and manufacturing sectors.

3. Advantages and Features
- Multi-Sensor Flexibility: Supports both RTDs and TCs, enabling mixed-input configurations.
- Precision Monitoring: ±0.5°C accuracy for critical temperature-sensitive processes.
- Dual-Channel Redundancy: Optional redundancy for safety-critical applications (e.g., offshore platforms).
- User-Programmable Alarms: Customizable alert/danger thresholds with <10 ms response time.
- Robust Design: IP65-rated enclosure for resistance to dust, moisture, and corrosive environments.
4. Application Fields and Case Studies
- Energy: Turbine bearing temperature monitoring in power plants.
- Oil & Gas: Pump motor temperature analysis in refineries.
- Manufacturing: Extrusion line temperature control in plastics production.
Case Study: A North American petrochemical plant reduced equipment failures by 40% using the 3500/60 to detect overheating in compressors, avoiding $800K in annual repair costs.
