Checking
When the temperature coefficient already set is accurate, the conductivity to be displayed
must be constant regardless of liquid temperature. The following check will make sure that
the temperature coefficient already set is accurate.
If, when the liquid temperature is lowered, a larger conductivity value is indicated, the
temperature coefficient already set is too small.
The opposite also applies. If a smaller conductivity value is indicated, the temperature
coefficient already set is too large. In either case, change the temperature coefficient so that
the conductivity no longer changes.
Matrix compensation
The compensation matrix is a table of temperature and conductivity values at differing
concentrations. These values are used to calculate the temperature compensation
applicable for a particular solution. Choose the component that you will be measuring in
your application, and where appropriate the concentration range. EXAxt will do the rest.
By following the routing:
Commissioning>> Measurement setup>> Temp.compensation>> Matrix Commissioning>> Measurement setup>> Temp.compensation>> Matrix
you gain access to the Matrix selection area.
Matrices are available for the common mineral acids and bases. In addition Ammonia and
Morpholine are included. In short by using the matrix method, specialist compensation is
available for the majority of applications in the power industry, water treatment, and chemical
manufacturing. The following matrices are available initially, but as with all Yokogawa
products, we are continually striving to improve both the quality and technological content.
Further solutions will be added to this list.
