Conductometer - concentration
meter with a contact sensor
Conductivity meter is designed as a transmitter: a single
channel monoblock or split measuring unit consisting of stucturally combined an electronic unit
and a sensor which is installing 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 5 m from the electronic unit (in split version). It is designed for measurement and monitoring of
specific electric conductivity (SEC), salts, alkalis and acids solutions.
Basing on known dependences between the SEC and the analyzed component
concentration, transmitters can be used as salinity meters and concentration meters (C-3110.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).
Analyzers C-3110.x.I-Ех (PT in the “I” enclosure) have
an explosion protection type "flameproof enclosure" provided with a marking "1Ex d IIB Т6 Х". Accessories:

1) The upper limit of measurement for submersible sensors is 100 mS/cm. 2) The upper limit of the temperature of the liquid to be analyzed is determined depending on the specific medium. 3) The sensor of the conductometer C-3110 can be manufactured to a temperature of up to 120 °C by special order;
P < 0,6MPa (execution of HT). 4) The reference temperature (° C) and the temperature coefficient (% per ° C) are set programmatically.
The conductometer has a galvanic isolation between the input and 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 measuring range can be set in the concentration meters 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 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.
