2.2 Designated use
Application and measured materials
The measuring device described in these Operating Instructions is intended only for level and
interface measurement of liquids. Depending on the version ordered the device can also measure
potentially explosive, flammable, poisonous and oxidizing materials.
Observing the limit values specified in the "Technical data" and listed in the Operating
Instructions and supplementary documentation, the measuring device may be used for the
following measurements only:
►
Measured process variable: Level and/or interface
►
Calculated process variable: Volume oder mass in arbitrarily shaped vessels (calculated from
the level by the linearization functionality)
To ensure that the measuring device remains in proper condition for the operation time:
►
Use the measuring device only for measured materials against which the process-wetted
materials are adequately resistant.
►
Observe the limit values in "Technical data".
Incorrect use
The manufacturer is not liable for damage caused by improper or non-designated use.
Verification for borderline cases:
►
For special measured materials and cleaning agents, Endress+Hauser is glad to provide
assistance in verifying the corrosion resistance of wetted materials, but does not accept any
warranty or liability.
Residual risk
The electronics housing and its built-in components such as display module, main electronics
module and I/O electronics module may heat to 80 °C (176 °F) during operation through heat
transfer from the process as well as power dissipation within the electronics. During operation the
sensor may assume a temperature near the temperature of the measured material.
Danger of burns due to heated surfaces!
►
For high process temperatures: Install protection against contact in order to prevent burns.
2.3 Workplace safety
For work on and with the device:
►
Wear the required personal protective equipment according to federal/national regulations.
