Teledyne Oldham Spyglass SG50-F-IR3-H2 Flame Detector
The Teledyne Oldham Simtronics SG50-F-IR3-H2 flame detectors provide unrivalled response, high performance and reliable detection for challenging fires such as hydrogen.
The near-infrared video technology embedded in option in the detector allows visualization of these fires which are often nearly invisible to the human eye. Video capture of a fire event includes one minute before the alarm and up to three minutes after the event.
SpyglassTM flame detectors offer the fastest detection of fires and explosions, providing the opportunity to reduce or prevent damage to property & equipment.
Key Features:
-
High immunity to false alarm, including arc welding
-
Detects hydrogen, ammonia, methane & syngas flames using three infrared wavelengths, with clear separation
-
5 selectable sensitivity levels
-
Ultra-fast detection within 40 milliseconds for fireballs or explosions
-
High speed (<0.5 s) option available for rapid detection of fires in challenging applications
-
Built-in-Test (BIT) – Automatic and manual internal self-test of window cleanliness and overall operation of the detector
-
HART® 7 - Easy configuration and diagnostic capability to assist preventative maintenance
-
Dirty optics warning for preventative maintenance needs
-
Heated window to avoid condensation and icing
-
Stainless steel tilt-mount with horizontal and vertical adjustment
-
SIL 2 capable - suitable for use in a SIL 2 compliant safety system
