Application and media
The device described in these instructions may only be used as a point level switch for

For special fluids and media used for cleaning, the manufacturer is happy to provide
assistance in verifying the corrosion resistance of fluid-wetted materials, but disclaims
any warranty or liability.
Residual risks

the temperature of the electronics housing and the assemblies contained therein may rise
to 80 °C (176 °F) during operation. When in operation, the sensor may reach a
temperature close to the medium temperature.
Danger of burns from contact with surfaces!
