Conductometer–concentration meter with inductive sensor
Conductivity transmitter (analyzer) is designed as a single-unit one-channel monoblock or
split measuring instrument which consists of an electronic unit and a sensor and is installed directly on a
controlled facility: a pipeline or a tank.
The sensor is structurally connected to an electronic
unit or can be placed at a distance of up to 9 m from the electronic unit.
Inductive analyzer sensor, proximity, made of a
material with a high chemical resistance to acids and alkalis. A strong design and smooth surface of
the sensor, as well as flow-through hole of a big diameter provides a
low probability of contamination and a possibility of the
sensor easy cleaning, possibility to work with contaminated liquids.
A built-in temperature sensor provides a temperature compensated measurement
of the solutions concentration.
It is designed for measurement and monitoring of
high values of specific electric conductivity (SEC), salts, alkalis and acids solutions.
Basing on known dependencies between the SEC and the analyzed component
concentration, transmitters can be used as concentration meters and salinity meters (C-3130.K)..
The analyzer can be used in the local Modbus (RTU,
ASCII) network (option) or be connected to the measuring
instrument by means of a current loop (option).
Application: heat power industry, chemical, petrochemical, pulp and paper, food processing,
dairy, brewing and other industries. In the dairy and brewing industry, it can be used as an indicator
of phase separation: water - milk, water - washing solution, etc.
manual or automatic selection of one of three measuring ranges;
temperature compensation mode selection: disabled, enabled, setting of reference temperature and temperature rates;
SEC (concentration) measured parameters and the temperature showing at display;
simplified calibration with one solution;
linear approximation of output specification (for C-3130.К) in
case the solution concentration has a non-linear dependence of SEC.
Analyzers C-3130.x.I-Ех (in the «I» enclosure) have an
explosion protection type "flameproof enclosure" provided with a marking "1Ex d IIB Т6 Х".

1) The reference temperature (°C) and the temperature coefficient (% per °C) are set programmatically.
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
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.
