Removing ink from recycled paper and turning it into raw pulp to make new paper is an involved process. pH is a critical parameter that influences ink removal efficiency. pH measurements in deinking mills can be difficult because of the varied nature of the raw material and thick consistency of the pulp. Sensors used in this environment must be rugged and chemically resistant. Many pH sensors will require regular daily or weekly cleaning. The Rosemount™ 396R Retractable pH Sensor is well suited to this type of application. The wide-area reference junction provides resistance to coating while the patented helical pathway prevents process intrusion into the inner reference chamber.
The Rosemount 5081 Explosion-Proof Transmitter is a single channel loop powered device that can accept input from a variety of liquid analysis sensors including: pH/ORP sensors, conductivity sensors (contacting and toroidal) and amperometric sensors (dissolved oxygen, chlorine and ozone). The transmitter features a rugged, weatherproof, corrosion-resistant enclosure to withstand harsh environments.
The Rosemount 1058 Dual Channel Transmitter provides confident liquid analysis measurement in a wide range of industrial, municipal and commercial applications. It is a 4-wire powered device that provides multi-parameter liquid analysis for digital and analog sensors, including inputs from pH/ORP sensors, ISE, flow, current, conductivity sensors (contacting and toroidal), turbidity sensors and amperometric sensors (dissolved oxygen, chlorine and ozone).
