The rugged construction and low cost of the LV750 Series level switch makes it a practical choice in a wide variety of applications for both liquids and solids, which may be electrically conductive or nonconductive. As a radio frequency switch, it can tolerate reasonable amounts of sticky build-up and still function flawlessly. For conductive liquids and materials with a high dielectric constant (greater than 30) that additionally have a tendency to "bridge" between the probe and container wall, a PTFE coated probe should be used. For chemical compatibility considerations, also request the ¾" nipple.
