Estimating the term…
A covered chamberless particulate detector includes a chamberless detector configured to produce a signal when particulate sensing events occurs, one or more optical emitters configured to emit one or more emitting cones of light, one or more optical sensors defining one or more receiving cones and configured to detect occurrence of particulate sensing events, and a protective cover defining an inside region and an outside region. Each of the one or more emitting cones of light is configured to overlap with each of the one or more receiving cones, thereby creating one or more sensing volumes which may be in the inside region, the outside region, or both regions. The protective cover can be transparent, partially transparent, or opaque, and can include apertures. The optical emitters and detectors can use one or more wavelengths, allowing discrimination of various airborne particulates.
A covered chamberless particulate detector comprising:
A method of using a covered chamberless particulate detector that comprises one or more optical emitters, one or more optical sensors, and a protective cover over the optical emitters and the optical sensors that defines an inside region and an outside region, the method comprising:
