Conductometer — concentration meter with contact or proximity inductive sensor

C-3101М.х
C-3101М.х.E
C-3101М.х.E.I-Ex

   The analyzer is designed for measurement and monitoring of specific electric conductivity (SEC) of salts, alkalis and acids solutions.
Following the well known dependences between the SEC and the analyzed component concentration, conductometer may be used as salinity meter and concentration meter.
   The analyzer is a single channel measuring device which consists of a primary transducer (PT) and a measuring instrument (MI). PM of conductometer can be equipped with a contact or proximity inductive sensor. The length of the three-wire communication line between the PT and the MI can reach 1000 m.

   Additional functions:

  • manual or automatic selection of one of four measuring ranges (for C-3101М.1, C-3101М.2);
  • selection of a temperature compensation mode: enabled, disabled, mode of ultra-pure water thermal compensation;
  • bilinear function by the output signal;
  • simplified calibration with one solution;
  • linear approximation of output specification (for C-3101M.К) in case the solution concentration has a non-linear dependence of SEC.

   C-3101М.x.E.I-Ех analyzers (PT in the «I» enclosure) are of "X-proof enclosure" explosion protection type, provided with a marking "1Ex d IIB Т6 Х".

   Execution with the index "E" meets the increased requirements for resistance to electromagnetic interference.

   Accessories:

  • holders;
  • Inductive sensors: AM-ES1, SI-315, AST-37HT.
Application: heat power industry, chemical, petrochemical, pulp and paper, food processing, dairy, brewing and other industries.
  • In the power industry it is used complete with the hydraulic panel with a cation exchange filter to provide control of highly demineralized water SEC.
  • In the dairy and brewing industry, it can be used as an indicator of phase separation: water - milk, water - washing solution, etc.

1) upper measuring limit for submercible contact sensors 100 mS/cm.
2) the upper limit of the temperature of the analyzed liquid to be is determined depending on the medium.
3) the sensor of the analyzer ECS-1.08 can be manufactured to a temperature of up to 120 ° C (HT version) by special order.
4) reference temperature (° C) and the temperature coefficient (% per °C) are set programmatically.

At the request of the customer, C-3101M can be equipped with a hydropanel with a cation-exchange H-filter.

The measuring instrument has a galvanic isolation between the input and the output.

At the request of the consumer, the manufacturer specifies a specific measuring range. The user can reconfigure the conductometer to a different range within this model.

At the request of the consumer, another measurement range can be set in the concentration meters intended for measuring the concentration in accordance with the normalized relationship between the SEC and the concentration of the analyte in the solution.

At the request of the consumer in the concentration meters, indication can be setted in percent or grams per liter in accordance with the normalized relationship between the SEC and the concentration of the analyte in the solution.
