Dust Level Sensor Arrangement for Dust Collection System
First Claim
1. Dust level sensor arrangement mounted into a lid of a dust collection container in which dust that descends from a dust separator positioned above said lid accumulates, and sensitive to the level of an upper surface of the accumulated dust in the container to alert an operator when the dust has risen to a predetermined level, the arrangement comprisinga sensor mounted in a penetration in said lid generating radiation that is directed downward into the drum and is reflected off the upper surface of the accumulated dust, and providing an output signal that goes from one sense to another sense when the dust has reached said predetermined level;
- anda strobe alarm that is coupled to said sensor and is triggered by the output signal of the sensor to generate a visible strobe alert signal when said accumulated dust has reached said predetermined level in the container.

Abstract
A level detector or sensor for a dust collection system has a threaded housing that seats in a penetration in the lid of a dust collection drum or other container, and can be adjusted mechanically in its mounting. The sensor has an adjustment to control the distance at which it picks up light off the collected material. An elongated flexible cable connects the sensor with an alarm strobe, which may be a low-power LED device, and can be positioned at a convenient location remote from the drum.

8. Dust level sensor arrangement mounted into an upper closure of a dust collection drum in which dust accumulates that descends from a dust separator positioned above said drum, and sensitive to the level of an upper surface of the accumulated dust in the drum to alert an operator when the dust has risen to a predetermined level, the arrangement comprising
a sensor mounted in a penetration in said lid generating radiation that is directed downward into the drum and is reflected off the upper surface of the accumulated dust, and providing an output signal that goes from one sense to another sense when the dust has reached said predetermined level; - and
an alarm arrangement that is coupled to said sensor and is triggered by the output signal of the sensor to generate an alert signal to alert an operator when said accumulated dust has reached said predetermined level in the drum. - View Dependent Claims (9, 10, 11)
