All-in-one integrated processor and viewing head solution.

Published on : Tuesday 30-11--0001

The U2 Series is an all-in-one integrated processor and viewing head system which is uniquely suited for single or multi-burner, multi-fuel and difficult flame detection applications. The all-in-one solution eliminates the need for a separate processor which saves on cabinets and wiring. Multiple models and sensor options meet difficult flame monitoring applications requiring a high level of discrimination.

Features

• Integrated viewing head and signal processor.
• Electronic check (no mechanical shutter) for self-check of the system.
• Independent configuration and adjustable gain settings for each sensor.
• Ten selectable flicker frequency filters for solid state UV and IR sensor (model dependent).
• Fully programmable using touch screen interface with easy to follow scrolling menu structure.
• Available in quick disconnect or PF versions with factory installed pigtail extension cable.
• Modbus RS422 communication for use with FLAMETOOLS-PC or FLAMETOOLS-HMI/U supports 248 loops and 32 loops, respectively.?
