OPTIBAR PM 5060 C
Damping For the damping of process-dependent measured value fluctuations, you can choose a suitable
integration time. The values which can be entered are from 0 ... 999 seconds with an increment of 0.1
seconds.
Integration time
Linearisation A linearisation is necessary for all vessels in which the volume does not increase linearly with the
level height, e.g. in a horizontal cylindrical or spherical tank, and the indication or output of the
volume is required. Corresponding linearisation curves are preprogrammed for these vessels. They
represent the correlation between the level percentage and vessel volume. By activating the
appropriate curve, the volume percentage of the vessel is displayed correctly. Enter the desired
parameters using the function buttons and save the entries. Note the following if the pressure
transmitter with corresponding approval is used as part of an overfill protection system according to
WHG (Water Resources Act): If a linearization curve is selected, the measuring signal is no longer
linearly proportional to the level. This must be taken into consideration by the user, particularly when
setting the switching point on the limit switch.
Type of linearisation
Current output In the current output menu, the saturation region for above or below a threshold is set. Under
"Current output min./max." these limit values can be set. The factory setting is 3.8 mA and 20.5 mA.
This corresponds to the NAMUR recommendation NE 43.
