A level switch is a device used to detect the level of substances such as liquid, chemical solvent, powders, lumps within tanks, silos, and hoppers. In addition, a level switch prevents overfilling of tanks and silos and ensures tanks do not run too low, possibly interrupting production.
Parker JRS Series Level Lead Switch with Detection balls and detection rods are completely enclosed and thus the products are not affected by pressure, vacuum, or gases. The lead switch is enclosed in a glass tube containing insert gas and thus the products operate safely in combustible gases. When the detection ball moves up and down due to buoyancy, the lead switches fixed to the upper/lower limit contact point positions are sensed.
