Technical Data

Measured variable: oxidative, bro‐
n
mine-containing disinfectant
– BCDMH: 1-Bromo-3-chloro-5,5-
dimethylhydantoin,
– DBDMH: 1,3-Dibromo-5,5-dime‐
thylhydantoin
– N-bromo-amidosulfonate
Applications:
n
– Typical applications are: the treat‐
ment of cooling water, disinfec‐
tion of slightly contaminated
waste water or the treatment of
water of a comparable quality
Measuring range:
n
– BCR 1-mA-0.5 ppm: 0.01 ... 0.50
mg/l (nominal gradient:
24.0 mA/ppm)
– BCR 1-mA-2 ppm 0.02 ... 2.00
mg/l (nominal gradient:
6.0 mA/ppm)
– BCR 1-mA-10 ppm: 0.1 ... 10.0
mg/l (nominal gradient:
1.20 mA/ppm)
pH range:
n
– 6.0 ... 9.5
– pH dependence< -10 %
Temperature range:
n
– 5 ... 45 °C (temperature compen‐
sated)
– No sudden changes in tempera‐
ture
Storage temperature:
n
– 5 ... 50 °C
Sample water conductivity:
n
– 500 μS/cm ... 10,000 μS/cm
Resolution:
n
– corresponds to the lower limit of
the measuring range
Maximum operating pressure:
n
– DLG III: 1.0 bar (free flow), no
negative pressure
Flow:
n
– In-line probe housing DLG III A/B
– Optimum: 60 ... 80 l/h
– Minimum: 40 l/h
– Maximum: 120 l/h
Cross sensitivity:
n
– Chlorine
– Chloramine
– Iodine
– CIO
2
– O
3
– Permanganates lead to too-high
results (too much is measured)
– Reducing agents such as sul‐
phide, sulphite, thiosulphate and
hydrazine lead to too-low results
(too little is measured).
Membrane cap service life:
n
– typically 3 months, depending on
the water quality
Material:
n
– Membrane cap made of PPE
– PVC electrode shaft
Supply voltage:
n
– 16 ... 24 V DC
– at least 35 mA at 16 V DC
Output signal:
n
– 4 ... 20 mA
Degree of protection
n
– IP 65
