On detecting the presence of oil, diesel or water, the Redeye sensor senses a change in the refractive index of the surface; this immediately puts the system into alarm. When in alarm an audio warning is sounded and a visual output illuminates. Simultaneously, the two internal relays switch to allow for onward signalling to a BMS for instance and mechanical switching of valves and pumps etc.
- Typical applications include oil/diesel storage tanks, fuel feed pipelines, boiler houses and plant rooms.
