Patol Infra-Red Heat Sensor 5410 ABS c/w Mounting Bracket (720-012)

The 5000 Series is an early warning infra-red transit heat sensor, which can trigger at temperatures as low as 100°C, when monitoring materials being transported on conveyor systems, before they have reached the ember or flame condition.

Its unique dual detector enhanced Infra-red monitoring has been created to detect black heat. Black body emissions occur for all material, the sensor is designed to detect a change in these emissions even at relatively low temperatures, when the material moves through its field of view.

Air purging from a mains operated Air Purged Blower (APB) feed is used to maintain a positive air pressure in the sensor enclosure, and ensures the prevention of dust settling on the sensor window.

The air supply is monitored by a pressure switch, which on air failure is signalled as a fault status.

The 5410 incorporates within the unit a series of user programmable SIL switches. Option selection including detector sensitivity settings, auto/manual reset sequence selection and single / coincidence voting from the two individual internal detectors for the alarm trip and shutdown outputs.

The sensor air pressure and signal cable connections are fault monitored and fail safe. The controller incorporates an aux. fault input & common fault output contact.

Key Features:

• Detection of hazards at temperatures below flame point including both embers and buried hot spots

• Twin high integrity detection circuit channels for maximum reliability
• Two wire operation - Powered by direct connection to standard fire trigger circuits or addressable loop interface
• Single / Coincidence voting output
• Timed auto reset / coincidence analyser circuit
• Tuned response — solar blind
• Volt free relay contact output operation selectable as standard
• Fault Monitored, with Test & Reset push buttons
• Field Programmable
