Safety instructions
1.1
Designated use
The sensor is suitable for continuous measurement of dissolved oxygen in water.
The sensor version determines what the sensor is especially suitable for:
• COS21D-A (measuring range 0.01 to 20 mg/l)
– Measuring, monitoring and regulating the oxygen content in fermenters
– Monitoring the oxygen contents in biotechnological systems
• COS21D-B (trace measurement with high CO
2
partial pressure, measuring range 0.001 to
20 mg/l, preferred operational range 0.001 to 2 mg/l)
– Monitoring inerting units in the food industry
– Monitoring the residual oxygen contents in carbonated media in the beverage industry
• COS21D-C (trace measurement, measuring range 0.001 to 20 mg/l, preferred operational
range 0.001 to 2 mg/l)
– Trace measurement in industrial applications such as inerting
– Monitoring residual oxygen contents in boiler feedwater
– Monitoring, measuring and regulating the oxygen contents in chemical processes
"
Caution!
The sensor must not be used for measurement in hydrogen loaded media.
The COS21D sensor must be connected to the digital input of the Liquiline transmitter using the
CYK10 measuring cable for non-contact, digital data transfer.
Any other use than the one described here compromises the safety of persons and the entire
measuring system and is, therefore, not permitted.
The manufacturer is not liable for damage caused by improper or non-designated use.

Installation, commissioning and operation
Please note the following items:
• Installation, commissioning, operation and maintenance of the measuring system must only
be carried out by trained technical personnel.
The technical personnel must be authorized for the specified activities by the system operator.
• Electrical connection must only be carried out by a certified electrician.
• Technical personnel must have read and understood these Operating Instructions and must
adhere to them.
• Before commissioning the entire measuring point, check all the connections for
correctness. Ensure that electrical cables and hose connections are not damaged.
• Do not operate damaged products and secure them against unintentional
commissioning. Mark the damaged product as being defective.
• Measuring point faults may only be rectified by authorized and specially trained
personnel.
• If faults can not be rectified, the products must be taken out of service and secured against
unintentional commissioning.
