Miniature Capacitive Level Switch-LF100D

Product introduction

LF100D series miniature capacitor (liquid) level switch uses induction rod to detect the electric capacity between the induction rod and the barrel wall with the measured object as the medium. When the induction rod is covered by material, the capacitance increases gradually. When the matching value of the circuit set inside the switch is reached, the circuit generates high frequency resonance, and the resonance signal is converted into switch action.

C = ( 0.0884  × K  · A) / TD K = dielectric constant

A = contact area

TD = Insulation layer thickness
