CC-801 conductivity controller for measurements in pure, ultra pure water, sewage and waste water. This controller is one of the new generation devices offering wide range of possibilities.
Designed to work in power stations, heat and power plants, water treatment stations and waste water treatment plants. It is a stationary device in housing resistant to dust and humidity (IP-65).
High measurement accuracy and stability has been provided.
The device has a large, graphic display, the conductivity and temperature results and the status of relays are showed simultaneously.
The graphic display enables to choose among the displayed information.
Apart from the basic data - conductivity and temperature, additional parameters like information about the ralay’s status or information about the last calibration date may be chosen to be displayed.
The used, in the controller, modern electronic elements have made the meter's memory independent to the power supply.
The device is easy, intuitive to operate and has an English language menu. It is equipped with a collective optical signalisation of the correct work and the condition of the regulation process.
CC-801 controller has an automatic temperature compensation system, which co-operates with the Pt-1000 temperature sensor.
The device enables 1-point calibration of the conductivity cell by entering the known constant K value or in a standard solution with automatic detection of the calibration point value. It is possible to calibrate the meter without the need of disconnecting the outputs.
The CC-801 controller is powered with standard 230 V voltage - which is galvanically isolated from the input clamps. It is possible to use other power voltage: 110/230/24V AC, 12-24 V (optional). Low power voltage is signalised by the instrument.
Outputs: relays (alarm or PID controlling), isolated digital: RS-485, MODBUS (ASCII and RTU); isolated current outputs: 0 ÷ 20 or 4 ÷ 20 mA.
The meter has also the real time clock with date.
In case of using the relays and exceeding the entered lower or higher limits, the proper relay is switched (minimum and maximum alarm) or fill in or frequency coefficients are changed (for the PID controller)
It's possible to connect a remote panel (keyboard with display), which enables controlling the device from up to 1 km distance.
Possibility of the data radio transmission from the measuring head to the controller.
24 months of warranty, quick warranty and after warranty service.
The controller has a CE certificate.

The conductivity cell cooperating with the meter is placed in a head. In case of measurements in tanks GCZ-1t immersion head is used, in which a conductivity sensor with steel electrodes is built in (description in separate catalogue card). The length of the head may be agreed (from 0.5 m ÷ 4 m) diameter of the head 50 mm. The head is equipped with a special handle to be hanged on an arm or a hook. The signal is amplified in the pre-amplifier, which is placed in the head.
The measurement in a pipeline is made with use of flow through head GCP-1t or GXP-1.
In case of high pressure in the pipeline a use of the lateral circulation with free outflow of small volume of the liquid through the GXP-01 head should be used.
The choice of the suitable head depends on the measured liquid and the conditions.
For the steel pipelines we offer a special mounting equipment for the conductivity cell which is mounted on the thread placed on the pipe and made according to our drawings. The preamplifier is placed next to the head. The choice of the right head depends on the type of the measured liquid, pressure, predicted measurement values and the conditions.
Description of the heads in separate catalogue cards.

Optionally there is a possibility of the radio transmission of data from the measuring head to the controller.
