The DCW 100 monitor is designed for measuring and regulation in disinfection process (chlorine, chlorine dioxide, ozone) and in particular for CCK sensors.
The auto-cleaning system ASR (patented) maintains automatically the sensor operational.
The cleaning is an electrochemical operation. The DCW 100 applies a suitable potential between the electrodes to produce oxygen and hydrogen without reagents addition. The gases eliminate the existing deposits.
The cleaning sequence is finished in 30 seconds and may be done twice a day. During the cleaning, the status is displayed; the regulation is set on stand-by.
Through the friendly using menu, an easy configuration is done on regulation, thresholds, temperature compensation and alarm events.
With the back lighted display it is easy to read perfectly the measure and temperature at anytime. The analogical output is galvanic insulated, and configured on various scales.

Display: Measurement – temperature – relays status – configuration menu back lighted LCD display, 2 lines
Configuration: Front keypad, 5 keys – Protected access through a key code
Temperature compensation: Manual or Automatic (Pt 100 Ω at 0°C sensor input)
Automatic cleaning: With the sensor type CCK only (auto-recognition)

Analogical inputs:
1 for CCK sensor
1 for temperature (Pt 100 Ω at 0°C sensor)

Flow controller input: For PNP inductive flow controller (NO status) – NO or NC configuration
Adjustable thresholds: 2 independents thresholds – adjustable as increasing or decreasing adjustable hysteresis

Alarm: 1 system dysfunction alarm, common to:
– Too long injection (adjustable timer from 0 to 90 minutes)
– Thresholds overriding
– Automatic cleaning
