Scaling The Measuring Range - IFM Electronic efector 500 PM2055 Bedienungsanleitung

Technical information / Functioning / Parameters

Scaling the measuring range

• With the parameter "Analogue start point" (ASP) the measured
value at which the output signal is 4 mA is defined.
• With the parameter "Analogue end point" (AEP) the measured
value at which the output signal is 20 mA is defined.
• Minimum distance between ASP and AEP = 25 % of the span (scal-
ing factor 4).

The output signal is between 4 and 20 mA in the set measuring range.
It is also indicated:
• System pressure above the measuring range: output signal > 20mA.
• System pressure below the measuring range: output signal drops to
max. 3.2 mA (depending on the scaling).
