• Enclosure: Encased in a powder-coated mild steel enclosure are the monitor electronics, featuring printed circuit boards, power terminals, and relay terminals. This enclosure is seamlessly linked to the Smart Sensor assembly via a quick-connect cable.
• Monitor Terminal Blocks: Positioned within the front panel of the enclosure, these blocks facilitate the connection of power, AC/DC relay, and 4-20mA analog output.
• LCD: 320x240 resolution display. By default, the monitor`s home screen prominently displays readings of hydrocarbon concentration along with any ongoing alarms.
• Keypad: The keypad includes a standard five-point navigation star for easy left, right, up, down, and enter commands. Additionally, shortcut keys are conveniently placed for quick access to main screens and menus.
• Smart Sensor Assembly:
• The Smart Sensor assembly is seamlessly linked to the monitor enclosure via a quick-connect cable.
• It comprises a transparent flow cell housed in Kynar, along with sealed optics and electronics, a humidity sensor, and a three-position flush valve.
• Three-Position Ball Valve: The valve is affixed to the Smart Sensor and connected to the monitor enclosure via wiring. It facilitates regular processes, flushing, and solution injection by managing the sample inlet and outlet lines of the Smart Sensor assembly.
• Luer-Lok Injection Port: The front port of the Smart Sensor is designated for injecting cleaning solutions using a syringe.
• Cleanout Port: Situated atop the Smart Sensor assembly, the inlet port enables access to the flow, facilitating manual cleaning with a brush when flushing alone is insufficient.
• Sample Inlet: The inlet port serves as the plumbing connection for attaching the sample intake line to the Smart Sensor assembly.
• Sample Outlet: The outlet port serves as the plumbing connection for attaching the sample outline to the Smart Sensor assembly.
• Flush Line Inlet: The flushing port serves as the plumbing connection for attaching a clean water line or pump to the Smart Sensor assembly.
