Abstract of the Disclosure An optical sensing head is provided for immersion in a solution carrying suspended solids and includes a chamber exposed to the solution and defining a sample path which extends through the solution. A spray mechanism is provided which forcefully removes light attenuating deposits which may accumulate on the surfaces of the chamber structure forming the sample path. A light beam is directed along an optical path (which includes as a portion thereof the sample path), and a light sensor is disposed at the other end of the optical path providing a signal indicative of the in- tensity of the received light. Plumbing is provided through which the exposed chamber may be flooded with clear water to thereby provide a low level suspended solids concentration for use as a reference. A light ab- sorbing member is provided which is selectively posi- tioned across the optical path to provide a high level suspended solids concentration reference when so posi- tioned. A controller receives the light sensor signal and operates to control the spray mechanism, the flooding function, and the positioning of the light absorbing member in a predetermined sequence. The sensing head and its control system provide a suspended solids measure- ment with a predetermined scale factor over a pre- determined range and further provide a correction when the optical path or controller circuit characteristics change. When the control is unable to properly provide the correction, an error indication is provided so that the suspended solids concentration readings will be known to be inaccurate.
