Opacity Measuring Apparatus
US Patent:
4076425, Feb 28, 1978
Filed:
Feb 17, 1976
Appl. No.:
5/658763
Inventors:
Julian Saltz - Princeton Junction NJ
International Classification:
G01N 2122
US Classification:
356205
Abstract:
An opacity measuring apparatus and method for monitoring the density of effluent flowing through a furnace stack includes a collimated light source directed in a first light path through the stack and the effluent flowing therein, which impinges upon a photoelectric detector providing a first electrical signal related thereto. A second light path, provided by a light pipe disposed in a path external to the stack, directs the light to the photoelectric detector which provides a second electrical signal related thereto. Circuit means provide a third electrical signal related to the ratio of the first electrical signal to the second electrical signal. Also included is an electrical correction signal related to the drift of the electronic circuitry and unwanted contamination occurring in the first light path which is subtracted from the first and second electrical signals prior to obtaining their ratio and circuitry to display and automatically calibrate the apparatus over relatively long periods of time.
