Optical Density Meter for Control
McNab, Incorporated announces an electronic
optical density monitor and controller for process control. The McNab
Model HSA 1 uses optical sensors and a solid-state indicator
controller. The indicator
controller has two alarm points, with output relays to signal when product
quality is unacceptable. The
sensors mount on the McNab Model HSA 1
integrated flow cell system. Materials
of construction are stainless steel with rugged glass lenses. The optical sensors measure turbidity or
clarity of the process across the pipe. Pipe sizes up to 8 inches can be provided. The in-line,
full-time, measuring system operates at line pressure up to 150 PSI, and
does not require a by-pass line or other sampling or cooling systems. The
unit utilizes the McNab flow cell system, developed over 25 years for
reliable measurement of in-pipe process fluids. The Model
HSA 1 is useful for measuring concentration levels and fluids that
must have fillers added to meet specifications. McNab also manufactures conductivity,
salinity, pH, and specific ion monitors, including models that feature
built-in chart recorders. For additional information on the McNab
Model HSA 1 or any McNab analyzer/controller, contact
