FineTek SB Series RF-Capacitance Solid Level Switch
Sticky, coating-prone materials are notorious for tripping false alarms on ordinary capacitance switches — the FineTek SB Series RF-capacitance (admittance) level switch is built specifically to avoid that problem, delivering accurate point-level detection even when material clings to the probe.
How It Works
The probe assembly is made up of a guard section, upper insulation, main probe, and grounding. As the medium reaches the main probe, the measured admittance rises and the switch actuates. What sets this design apart is the active guard section, which is specifically engineered to reject material build-up on the probe — so accuracy holds up even when product sticks to the insulation.
