8. General Safety and User Instructions
8.1 Safety
Intended use
The sensor must be used solely for the level detection of liquids in applications which are specified and approved
by FAUDI Aviation GmbH.
The sensor must only be used for media against which the housing material and sensor tip are resistant.
Staff qualification
Installation and operating personnel must be qualified and instructed . This applies in particular to assembly,
installation and explosion protection. Make sure that the staff has read and understood these instructions.
Technical condition
Use the sensor only when in perfect technical condition. Only use FAUDI Aviation GmbH accessories.
FAUDI Aviation GmbH will accept no liability for other manufacturers’ accessories.
Risk of burns from hot media
During operation the sensor housing may warm up to over 5 °C. When working with hot media provide protection
against burns.
Explosion hazard areas
Ensure that safety requirements are complied with. Do not use equipment that would be exposed to hard impacts.
8.2 Installation for Various Applications
When using the SLUGGUARD
®
without the dedicated ball valve – use sufficient sealant material like PTFE (Teflon
tape) to seal the sensor.
