DULCOTEST® Conductivity Sensors


Conductivity Measurement

The electrolytic conductivity is the most important measurement of the chemical process analysis after the pH value. With electrolytic conductivity, all processes where salts, acids, and brines play a role can be controlled, guided or regulated with measuring technology.

For all applications it is always important, to measure the electrolytic conductivity as exactly, promptly and reliably as possible at high availability of the measuring values either for control, guidance or regulation of the processes.

Frequently Asked Questions

Standard Lead Times for Products / Expediting

Standard lead times are listed below. If you need an order expedited, please contact your customer service representative. Please be aware that overnight shipments receive priority over ground shipments. Gala/Beta/Concept - 3 days Sigma series - 5 days ProMus - 2 weeks Dulcometer 3-4 days

When discharging to atmosphere, what steps will improve repeatability of dosing?

Installing a spring in the discharge valve of the pump gives some improvement, but for the maximum improvement, a backpressure valve should be installed at the end of the line.

What variables can be measured or controlled with ProMinent equipment?

We can measure or control pH, Redox, Free or Total Chlorine, Chlorine Dioxide, Conductivity, Ozone, Peracetic Acid, Hydrogen Peroxide and Dissolved Oxygen.

Can you explain what the different options are using the Ident-code for the D1C controller?

The Identcode for a D1C has 13 parameters that can be specified. The first parameter is the type of mounting such as wall or panel mount. Then the operating Voltage must be selected. The measured variable is the parameter being measured such as pH, chlorine, Redox ? The next selection is the connection of measured variable, which selects how the sensor is wired, such as an SN6 connector. The correction variable selects whether there is pH or temperature correction. The next variable is feed forward capability. This signal can be used for metering proportional to the flow rate. The control input allows control by contact closure. The signal output function can be set up as measured, controlled or correction variable. The power control variable pertains to the alarm functions and how and what they control. The pump control option is set up for whether pumps will be controlled. The control characteristic sets the pump up for proportional control band or the more sophisticated PID control. The interface is not used at this time. The last variable allows for the selection of the language.

When programming the D1C, what options can I enable or disable?

The D1C controller can be set up for a complete operating menu or a reduced menu. The reduced operating menu permits operation of the most important parameters, but will not allow the operator to change system parameters that are normally set up once, during initial installation. The complete operating menu allows all parameters to be changed.

What is feed forward control?

This signal can be used for metering proportional to the flow rate.

What option is required on controllers when you want to connect to a chart recorder?

The controller must have the signal output option for measured value for recording or two mA outputs.

What do I need to order with a D1C?

SEE WORD DOC

What do I need to order with a D2C?

SEE WORD DOC

I am working with a ProMinent D1C controller and controlling pH. I keep getting a check sensor error. What is causing this problem?

The problem may be that the checkout time is set too low. This feature is used to detect a defective sensor: if the value is set to 1 second, the processor looks for changes on the sensor readings; if the display does not change during this interval, a check sensor will result. This feature can be set from 1 to 9999 seconds or turned off in the measure value mode of the controller. Turn the checkout time to off or set the measured time to at least 60 seconds, so the sensor is checked once a minute instead of once every second.

Where are conductivity controllers most commonly used?

Conductivity controllers are used in industries including, paper, pharmaceutical, plating, electronics, breweries, power production, and plating. Two very popular applications are bottle washing and cooling towers.
