Information Technology for Flame Detection
Flame detection with Information Technology at the device level –
accurately and quickly detect flames from a wide variety of sources in
difficult industrial applications without false alarms. This urgent safety infor-
mation is provided to operators and networks quickly via a selection of
desired communication technologies.
UV, UV/IR, IR3, IR and Tri-Spectra designs – provide end user flexibility for
selection of the appropriate technology [Tri-Spectra includes UV/IR/Visible]
SIL 2 certified
– meets Safety Integrity Level requirements
Continuous internal diagnostics – to assure reliable operation and fault
identification
Built-In Test (BIT)
– checks for window obscurity
Alarm relays – provide contact outputs for Alarm, Fault and Auxiliary
0-20 mA output – stepped values provide meaningful diagnostic and alarm information
HART protocol
– for maintenance and asset management
RS-485 Modbus – serial Modbus RTU output
ATEX, IECEx, FM, and CSA – explosion proof and performance approvals
Applications – flame detectors available for hydrocarbon and non-hydrocarbon based flames
