Pressure-temperature
ratings
The following pressure/temperature diagram refers to the entire measuring device and not
just the process connection.
A0026823-DE
Secondary containment
pressure rating
The sensor housing is filled with dry nitrogen on delivery and protects the electronics and
mechanics inside.
The housing does not have pressure vessel classification.
Flow limit
Pressure loss
System pressure
The relative accuracy of the density measurement increases with increasing system
pressure.
Thermal insulation
Due to a low thermal capacity of the medium, the medium temperature can be greatly
affected by the ambient temperature through the supply line and the measuring device. The
influence of the ambient temperature on the medium temperature can be reduced by
insulating the supply line.
Vibrations
Due to the high operating frequency of the micro-channel, vibrations (<20 kHz) do not affect
measuring accuracy.
