وصف
Description
The Bently Nevada 3300/65 Dual Valve Position Indicator is a specialized monitoring module engineered for the 3300 Series system. This unit provides two independent measurement channels specifically designed to track valve position in steam turbines and other critical rotating machinery. By delivering precise position feedback, the module facilitates machinery protection through integrated alarm and trip logic, ensuring operational stability.
Features
- Dual-channel architecture for independent valve position monitoring.
- Integrated alarm setpoints for Alert and Danger conditions.
- Visual status indication via front-panel LEDs (OK, Bypass, Alert, and Danger).
- Proportional analog output signals for external control system integration.
- Rack-mounted design compatible with standard 3300 Series system infrastructure.
Applications
This module is primarily utilized in power generation and heavy industrial facilities for monitoring steam valve positioning. It is essential for systems requiring continuous feedback to prevent mechanical overtravel or valve-related failures in turbine-generator sets.
