8 Basic safety instructions
8.1 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.
• Measuring point faults may be repaired only by authorized and specially trained personnel.
Repairs not described in the Operating Instructions provided may only be carried out
directly by the manufacturer or by the service organization.
8.2 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 (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.
The sensor must be connected with the CYK10 measuring cable for non-contact, digital data
transmission to the digital input of the Liquiline transmitter.
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.
8.3 Workplace safety
As the user, you are responsible for complying with the following safety conditions:
