Abstract
A temperature control system for the fluid in a textile dyeing vat 10. Collimated light from a single source 18 is passed through a transparent section 14 of a shunt tube 12 coupled to the vat, and through a transparent, movable, wedge-shaped container 28 filled with a reference dyeing fluid. The emerging light intensities are detected by photocells 24, 36 whose outputs are fed to differential amplifiers 38, 40. The output of the former controls the movement of the container 28 which the output of the latter controls the temperature of the vat through a valve device 46.
