SWI L250AD Series | Integral Dispensing Tube Level Switches

Description

The L250AD is a combination single or dual-point level switch and integral dispensing tube designed for use in the pharmaceutical industry. The unit has the capability of dispensing liquids as well as monitoring their levels of critical laboratory solutions from within a plastic-lined container. Its spring-loaded mount adjusts the sensor for optimum submergence and its ultra low-level float requires only 3/16" of liquid to operate. Options include the choice of a polysulfone/polypropylene or stainless steel construction with a variety of switch types.

Principles of Operation

A float with an internal magnet rises and falls in correlation to the container's liquid level. As the float moves, its magnetic field actuates the hermetically-sealed contact inside the switch tube. When the liquid level falls, the contact closes and activates a relay (not included) to indicate the low level. In addition, a separate "pick-up tube" runs parallel to the switch tube and draws fluid from the container.
