Littelfuse Pump Controls and Liquid Level Controls
Roll Over to Zoom
The 460-15-100-LLS is a liquid level sensor to detect the presence of conductive liquids. A probe is mounted at the desired tank level and connected to the Littelfuse pump control. When the probe is submersed, the relay’s output contacts will change state as soon as the debounce time expires. The adjustable debounce timer is intended to prevent nuisance actuating due to waves or splashing in the tank.

Relay logic can be inverted so the relay’s output contacts change state when the probe is no longer submersed. This makes the unit versatile for use in pump-up and pump-down applications.
