DABECO BR1 Bromine Sensor

Product catalog summary

Overview: The BR1 indicator is designed for measuring bromine levels in various water types, including drinking, swimming pool, service, process, and sea water. It utilizes a membrane-covered, amperometric potentiostatic 3-electrode system for measurement.

Specifications:

Measuring System: Available in analog and digital versions, with options for galvanic isolation.
Measuring Range: Sensor slope varies between 65% and 150% of nominal, affecting the measuring range.
Temperature: Operating water temperature is 0 to 45°C, and ambient temperature is 0 to 55°C. Automatic temperature compensation is included.
Pressure: Maximum working pressure is 0.5 bar without a retaining ring and 3 bar with a retaining ring in TARAflow FLC.
Flow Rate: Recommended flow velocity is 15-30 L/h.
pH Range: Operates effectively between pH 6.5 and 9.5.

Procedures:

Run-in Time: Approximately 2 hours for first start-up.
Response Time: T90 is approximately 2 minutes.
Calibration: Conducted at the device using analytical determination methods specific to the bromine agent.
Maintenance: Regular signal checks are recommended weekly, with membrane cap changes annually and electrolyte changes every 3-6 months.

Interferences: The sensor also measures Cl2, ClO2, and O3, and can be affected by corrosion inhibitors and water hardness stabilizers.

Connections: Various connection options are available, including mV, Modbus, and 4-20 mA versions, with specific cable length limitations based on signal processing type.

Materials and Size: The sensor is made from microporous hydrophilic membrane, PVC, PEEK, and stainless steel, with dimensions varying slightly based on the version.

Storage and Transport: Sensors should be stored dry and without electrolyte, while electrolytes should be kept in original bottles away from sunlight.

Spare Parts: Includes membrane caps, electrolytes, emery, and O-rings, with specific part numbers provided.

pH Dependence: A diagram illustrates the relative dependence on pH, showing optimal performance around pH 7.2.
