Controller DULCOMETER® D1Cb/D1Cc

The controller DULCOMETER® D1Cb/D1Cc can be used for control tasks in potable water treatment, waste water treatment and many other areas. Safe, convenient and clear, thanks to the large illuminated graphic display, plain text operating menu and pH sensor monitoring.

Product description

The water analysis workhorse

The D1Cb/D1Cc controller is a 1-channel P/PID controller Controls processes automatically to ensure that the specified values (e.g. pH: acid or alkaline) are maintained even in the event of interfering influences. more in the glossary for the measured variables The physical variables to be determined by measuring. more in the glossary pH, ORP, chlorine, chlorine dioxide Chlorine dioxide is an exceptionally reactive gas, which is not stored due to its instability ... more in the glossary, chlorite, ozone Significantly less environmentally harmful by-products result from the generation and use of ozone ... more in the glossary, bromine, peracetic acid Peracetic acid is particularly used in the food and beverage industry, but also for disinfection in ... more in the glossary, hydrogen peroxide Due to its complete biodegradability, hydrogen peroxide is a disinfectant and oxidising agent ... more in the glossary, fluoride, dissolved oxygen The measured variable "Dissolved oxygen" indicates the volume of gaseous oxygen physically dissolved in the aqueous phase in mg/l (ppm). more in the glossary and conductivity via mA. The sensors for pH and ORP can be directly connected via coaxial cable or using the 4-20 mA sensor input. The controller can bidirectionally control the measured variables The physical variables to be determined by measuring. more in the glossary, monitor limit values and transmit the measured value via an mA output, e.g. to a PLC Programmable Logic Controller. The mA output can optionally also be configured as an interference variable output. The controller has two pulse frequency outputs to control two metering pumps (raise and lower). Two output relays can optionally be used as limit value relays or to control motor-driven pumps or solenoid valves. An alarm relay signals the occurrence of a fault. A digital input is used to switch off the control or to process a sample water limit contact by remote control. The impact of temperature on the measurements can be provided by temperature measurement or by manual input. Menu-driven operation is possible in 20 languages.

Your benefits

  • Flexibility through free selection of variables from all measured variables
  • Safety through sensor monitoring of pH for glass breakage and line breakage
  • Flexibly upgradable, thanks to subsequent activation option of functions by means of an activation code
  • Various installation options: wall-mounted or installation in a control cabinet

Field of application

  • Measurement and control of water parameters in industrial and process water treatment plants
  • Waste water neutralisation
  • Measurement of the pH value and the disinfection parameters in potable water treatment and in the food and beverage industry
  • Measurement and control of the hygiene parameters in swimming pools
