BENTLY 79492-01 Six-Channel Temperature Monitor
1. Product Description
The BENTLY 79492-01 is a compact, high-performance temperature monitoring module designed for industrial rotating machinery in sectors such as power generation, oil and gas, and manufacturing. As part of the BENTLY 3500 Machinery Protection System, it provides six independent channels for real-time temperature measurement using Resistance Temperature Detectors (RTDs), including PT100, PT500, and Ni120 sensors. The module processes data, compares it against user-configurable alarm thresholds, and triggers alerts or shutdowns to prevent equipment damage. Its modular design ensures seamless integration with other 3500 Series components for comprehensive machinery health monitoring.
