Overview
The Bently Nevada 84933-02 is a six-channel temperature monitor (model 3300/35) designed for precise industrial temperature measurement and monitoring. This RTD-based monitor enables simultaneous, independent temperature measurement from up to six different sources, making it ideal for machinery monitoring, process control, and predictive maintenance applications. The unit provides standard 4-20 mA analog output signals for direct integration with control systems and data acquisition platforms.
Key Features
- Six Independent Channels: Monitor temperature from six separate sources simultaneously
- RTD Input Support: Accepts Resistance Temperature Detector (RTD) sensors with user-programmable RTD types (e.g., 100 Platinum 0.00385, 4-wire configuration)
- 4-20 mA Output: Standard analog signal output for seamless integration with industrial control systems
- On-Line Monitoring: Real-time temperature measurement with dedicated alarm relay capability
- DIN Rail Mounting: Compact design enables straightforward installation in control panels
- Industrial Robustness: Suitable for harsh environments and demanding applications including machinery, power plants, and process industries
