Controler DULCOMETER® D2C cu doua canale

Controler DULCOMETER® D2C cu doua canale

Avantaje

  • Universal, pentru masura si controlul combinat al numeroase variabile: pH / Redox, pH/ clor, pH/ pH, pH/ Dioxid de clor şi clor/ clor
  • Ideal adaptat cerintelor procesului datorita numeroaselor trepte de extensie
  • Integrare facila in procesul tehnologic: multiple posibilitati de instalare a senzorilor si de control al echipamentelor de dozare
  • Procese optimizate datorita functiunilor speciale precum dozare in sarcina de baza, multiple functiuni de valoare limita.
  • Siguranta: monitorizarea valorii limita cu temporizare la dozare.
  • Usor de operat, prin intermediul afisajului grafic si al meniului in 8 limbi.
  • Afisaj grafic generos pentru valori masurate, valori de corectie si informatii.

Controlerul cu doua canale DULCOMETER® D2Ceste un dispozitiv de masura si control bazat pe thenologia cu microprocesor si care ofera un inalt grad de fiabilitate intr-un spectru latg de aplicatii. Controlerul este configurabil si, prin urmare, poate fi adaptat pentru a satisface nevoile dumneavoastra specifice. Cerinta aplicabula tipului de control, tipului constructiv (montaj pe perete, pe panou etc.) precum si altor parametri. Dumneavoastra specificati de ce aveti nevoie si platiti doar pentru atat.

Applications for measured quantity combinations pH/Redox, pH/Chlorine and Chlorine/Chlorine

  • Water treatment for swimming pools
  • Differentiating measurement of Chlorine, reduction of combined Chlorine in swimming pool water purification
  • Cooling water treatment

Application for measured quantity combination pH/pH

  • Effluent treatment
  • Neutralisation
  • All applications have to be fitted with a redundant pH measuring device for safety reasons

Application for measured quantity combination pH/Chlorine dioxide

  • Combating legionella
  • Drinking water treatment

Features

  • Threshold value monitoring with adjustable automatic cut-out as standard
  • Probe connection in two-wire technology, unaffected by interference
  • 2 signal outputs 0/4 – 20mA galvanically separated
  • Different designs for wall and panel mounting
  • 1 digital input for pause and error monitoring of sample water
  • 1 digital input for super chlorination or basic load
  • Basic load dosing (additive effect)
  • Unidirectional control for pH/Redox, pH/Chlorine dioxide and pH/Chlorine, bidirectional control for pH/pH
  • Neutral zone control for pH/pH
  • Temperature compensation for pH
  • Chlorine difference measurement for Chlorine/Chlorine
  • Regulating output for minimising combined chlorine for Chlorine/Chlorine
