Technical information

The unique solar blind sensor with infrared reflective cone optical focus has been created to detect moving black heat with a spectral response between 5 to 14 µm (wide band). Black body emissions occur for all materials and the sensor is designed to detect and respond to a small change in radiant emissions even at relatively low temperatures. All sensors include adjustable sensitivity between 10 to 40 µW.

The infrared heat sensors are typically mounted at 1 to 1.5 metres above the conveyors and aligned such that the monitored potential hazard passes through the sensors field of view. The sensors provide outputs for Alarm / Trip and Fault monitoring.

The range of 5000 series sensors include continuous air purging to maintain an automatic cleaning system that ensures the prevention of dust settling on the sensor lens. Several models are available including specialist sensors with ATEX certification for hazardous dust environments and glass free Stainless Steel sensors suitable for food processing areas.
