2 Basic safety instructions
2.1 Requirements for the personnel
• Installation, commissioning, operation and maintenance of the measuring system may
be carried out only by specially trained technical personnel.
• The technical personnel must be authorized by the plant operator to carry out the
specified activities.
• The electrical connection may be performed only by an electrical technician.
• The technical personnel must have read and understood these Operating Instructions
and must follow the instructions contained therein.
• Faults at the measuring point may only be rectified by authorized and specially trained
personnel.
Repairs not described in the Operating Instructions provided must be carried out only
directly at the manufacturer's site or by the service organization.
2.2 Designated use
The sensor is designed for continuous measurement of dissolved oxygen in water and
aqueous solutions, and also for continuous measurement of oxygen in gases.
The sensor is particularly suitable for:
• Monitoring inertization equipment in the food industry
• Monitoring, measuring and regulating the oxygen content in chemical processes
• Monitoring of fermentation processes
NOTICE
Halogen-containing solvents, ketones and toluene
Halogen-containing solvents (dichloromethane, chloroform), ketones (e.g. acetone,
pentanone) and toluene have a cross-sensitive effect and result in decreased measured
values or, at worst, in the complete failure of the sensor!
‣
Use the sensor only in media that are free from halogens, ketones and toluene.
For non-contact digital data transmission, the sensor must be connected to the digital
input of the Liquiline transmitter using the CYK10 measuring cable.
Use of the device for any purpose other than that described, poses a threat to the safety of
people and of the entire measuring system and is therefore not permitted.
The manufacturer is not liable for damage caused by improper or non-designated use.
2.3 Occupational safety
