Sterling Plumbing 882 00276.00 specifications Example

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 = __________
