LLC1 Series
Littelfuse LLC1 Series

The LLC1 Series is a single probe conductive liquid level control designed for OEM equipment and commercial appliances. This unit may be ordered with fixed fill or fixed drain operation. A time delay (1-60s) prevents rapid cycling of the output relay. On adjustable units, the sensitivity adjustment allows accurate level sensing while ignoring foaming agents and floating debris. Isolated AC voltage is provided at the probe to prevent electrolysis. A trickle current of less than 1mA determines the presence or absence of liquid between the probe and common. The LLC1 Series printed circuit board is conformal coated to resist moisture and corrosion.

Features & Benefits:

 

  • Isolated AC voltage on probe: Prevents scale buildup on the probe
  • Open PCB design: Cost effective design for OEM equipment and commercial appliances
  • Conformally coated PCB: Protects against moisture and corrosion
  • Sensitivity adjustment: Provides accurate level sensing while ignoring foam or floating debris
