BENTLY 3500/65 145988-02 Temperature Monitoring Module
1. Product Description
The BENTLY 3500/65 145988-02 is a high-precision temperature monitoring module designed for industrial machinery in sectors such as power generation, oil and gas, and manufacturing. As part of the BENTLY 3500 System, it provides 16 channels of temperature measurement, supporting both Resistance Temperature Detector (RTD) and isolated tip Thermocouple (TC) inputs. The module processes real-time data, compares it against user-programmable alarm thresholds, and triggers alerts or shutdowns to prevent equipment damage. Its modular design ensures seamless integration with other 3500 Series components (e.g., vibration, speed monitors) for comprehensive machinery protection.
