Tank Mount pH Control System,

0 pages

This sensor assembly may be mounted to the cover of the ink pail or to a Norcross viscosity measuring element ( shown below).

The sensor tip is connected to a transmitter, by means of a plastic pipe with internal wiring. The transmitter converts th native pH probe signal into a 4-20madc sigͭnal. A signal suitable for transmission to the remotely mounted MP2000pH controller.

The operator puts the desired pH value into the controller as a set point. The controller compares the setpoint with the actual pH value. When the pH drops below the setͭpoint, the controller turns on an amine addition valve, for an appropriate time period.

The controller has a built in time delay which allows it to add amine once every 2 minutes.

All pH sensor assemblies require periodic calibration. In order to make this process simple, we offer pH testing accessories.

The accessories include a test meter, pH probe support, buffered solutions, directions for use and a convenient carrying case

The end of the pH sensor assemͭbly must always be in ink or water. If the tip is allowed to dry or is

damgaed, it must be replaced and the whole assembly recalibrated.
