Process conditions
For the process conditions, please also note the specifications on the type label. The lowest value
always applies.
For the process temperature and the vessel pressure, you also have to note the specifications on
the type label! Always the lowest value is applicable!
Process temperature (measured on the
process fitting)
-40 … +200 °C (-40 … +392 °F)
2)
Time span after a sudden measuring distance change by max. 0.5 m in liquid applications until the output signal
has taken for the first time 90 % of the final value (IEC 61298-2).
3)
Outside the specified beam angle, the energy of the radar signal has a level which is reduced by 50 % (-3 dB)
4)
