DABECO AS2 Free Chlorine Sensor
DABECO AS2 Free Chlorine Sensor
- Application: Suitable for cold and hot drinking water up to 70°C.
- Chlorination Agents: Compatible with sodium hypochlorite, calcium hypochlorite, chlorine gas, and electrolytically generated chlorine.
- Measuring System: Uses an amperometric potentiostatic 3-electrode system.
- Electronic Versions: Available in analog, digital, and mA versions with varying galvanic isolation.
- Measuring Range: Sensor slope varies from 65% to 150% of the nominal slope.
- Temperature: AS2 operates from 0 to 50°C, AS3 from 0 to 70°C.
- Pressure: Maximum pressure is 0.5 bar without a retaining ring and 8 bar with a retaining ring in TARAflow FLC.
- Calibration: Uses the DPD-1 method for chlorine and chlorine dioxide.
- Maintenance: Weekly signal control is recommended, with cleaning and electrolyte changes as needed.
- EMC Tested: Complies with electromagnetic compatibility standards.
- RoHS Compliant: Materials comply with the Restriction of Hazardous Substances Directive.
- Cleaning Equipment RV1: Recommended for AS...-CL to extend maintenance intervals and stabilize signals.
- Flow Rate: Specifies minimum flow rates for optimal operation.
- Includes cleaning equipment, spare hulls, electrolytes, and O-rings with specific part numbers.
- Chlorine Measurement: Specifications for analog and digital outputs, measuring ranges, resolutions, and connection types.
- Chlorine Dioxide Measurement: Similar specifications with variations in measuring ranges and outputs.
Catalog excerpts
- direct installation on the sensor - approaching flow to the sensor through RV1 - cleaning effect of RV1 is moderate, i. e. weak deposits on the electrodes will be removed, e. g. weak rust films - for a correct and proper operation of sensor with cleaning equipment RV1 flow chamber FLC-3 has to be used!! - Sensor can be upgraded at any time - Using with AS...-CL: => slope is approx. 3 times higher (see diagram “AS-Chlorine Sensor with and without RV1”) - Using with AS...-CD: => slope is approx. 2 times higher (Subject to technical changes.)
