  • 41. PRESENTATION : New Tech Standard vs SMARTLevel vs. What happens now with material build-up? Resistor - A thin film has a low electrical conductivity. - Extremely high AC frequency (~6.5MHz) causes additional resistance versus ground. GND Sensor doesn’t recognize material build-up anymore as valid target without this ground reference. WWW.BALLUFF.COM
