Technical Examples

Sieve screen level sensing in a filtering apparatus (10) for filtering fine powder material (M) which includes a sieve (12) having a material inlet (24) and a material outlet (26), and a sieve screen (14) is disposed within the sieve (12) between the material inlet (24) and outlet (26) such that the material (M) must pass through the sieve screen (14) to enter the material outlet (26) and thereby exit the sieve (12). An input valve (22) controls the flow of material (M) into the sieve (12) through the material inlet (24). A sieve screen level sensor assembly (20) senses a level of material (M) accumulated upon the sieve screen (14), and issues a level sense signal (66) indicative of that level. A programmable logic controller (60) receives the level sense signal (66) and controls the inlet valve (22) dependent at least in part thereon to thereby control the flow of material (M) into the material inlet (24).
