Description
Patol 5012 Stainless Steel Infra-Red Heat Sensor without Controller
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 eight 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 compressed air feed is used to maintain a positive air pressure in the sensor enclosure, an air knife 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 5020 controller is directly connected to the sensor. A series of user programmable DIL switches allows option selection including detector sensitivity settings, auto/manual reset sequence selection and single / coincidence voting from the four individual internal detection channels 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.
