Bently Nevada™ 3500/60 Temperature Monitor — Part No. 163179-01
Product Overview
The Bently Nevada 3500/60 (Part No. 163179-01) is a six-channel temperature monitoring module designed for the 3500 Series Machinery Protection System. Manufactured by Bently Nevada, a Baker Hughes business, this module delivers continuous, online temperature surveillance for critical rotating machinery and process equipment. It conditions temperature inputs from both Resistance Temperature Detectors (RTDs) and Thermocouples (TCs), comparing measured values against user-programmable alarm setpoints to drive protective relay logic and alerting functions.

Key Features
| Feature | Description |
|---|---|
| Channels | 6 independent temperature monitoring channels |
| Input Types | RTD (Resistance Temperature Detector) and Thermocouple (TC) |
| Configuration Flexibility | RTD/TC non-isolated or TC isolated I/O module variants |
| Channel Isolation | 250 Vdc channel-to-channel isolation (TC isolated version) |
| Alarm Setpoints | User-programmable Alert and Danger thresholds via 3500 Rack Configuration Software |
