Overview

The 3500/64 Dynamic Pressure Monitor is a single-slot, four-channel monitor designed to accept input from various high-temperature pressure transducers. It uses these inputs to drive alarms and provides the following functionalities:

• One proportional value per channel (bandpass dynamic pressure).
• Configurable bandpass corner frequencies through 3500 Rack Configuration Software.
• Additional notch filter capability if needed.
• Provides a recorder output for control system applications.
