Digital Dosing Units

If a current signal is available (0 - 20 mA) calculate the frequency output of the extruder for the

lower / upper working area using the formula:

Frequency [Hz] = Input current [mA] x 10000 [Hz]

20 [mA]

Note the data:

Min. input frequency = __________ Hz

Max. input frequency = __________ Hz

Calculate the span factor using the formula:

Span factor [Hz / rpm] = Frequency [Hz]____________

Rotational speed of the extruder [rpm]x 10

Note the data:

Span factor = __________
