1.1 Integrated SafeFlame Scanner
Uvisor™ SF910i is an instrument designed to detect and analyze flames easily and
reliably. It takes advantage of the latest technologies available to make flame detection
and analysis as cost-efficient as possible, while retaining ABB's rock-solid reputation for
reliability.
The main characteristic of the SF910i is its "Integrated" structure. All the electronics from
the sensor(s) to the wiring terminals (or quick release connector), including the processing
unit, the relays, and the communication ports are contained in the scanner enclosure.
For SF910i, other important capability is its one communication line. The communication
protocol is the simpler "MODBUS" protocol for greater flexibility.
SF910i is easy to install and straightforward to configure thanks its software engineering
tool Flame Explorer™ and flexible to operate.
SF910i -*- PYR is the innovative approach of ABB to meet the stringent requirement of
safety and the challenging demand of qualitative information for a combustion monitoring
system.
SF910i -*- PYR flame scanner bases on the proven rock solid technology of the standard
SF910i flame scanner series and it features the sensing element for the analysis unit to
compute the flame temperature measurement in real time.
SF910i -*- PYR flame scanner offers a valuable input to improve the total NOx reduction
control strategy by monitoring the local combustion process.
Flame Scanner SF910i is a simple "flame detector device" (but not an "independent
flame detector device") as part of a higher-level burner control system. Flame scanners
relay output will connect to customer's BMS (Burner Management System), MFT (Master
Fuel Trip), or DCS/SIS systems. Inside these systems, before shutting off/driving valves,
there are 3oo4 or 1oo2 voting logic between several redundancy scanners output relays.
