Cristal instruments provides side mounted magnetic level switches [type cls-110] that are floatoperated working on magnetic repulsion principle. Constructional properties includes its simple in design and robust in construction together with strict quality control makes the switches very reliable product. These switches can be used for initiating high or low audio-visual singals or automatic level control of liquids in pressurised or open tanks, containers, hot water service, sterilising equipment and a variety of process control fluid tanks. The float assembly carries a permanent magnet with the float movement. This magnet repels another magnet kept inside the switch housing which in turn actuates a micro-switch having snap action of contacts. The switches are provide with 3-way plug-in connector. Terminals 1 and 2 are normally open and 2 and 3 are normally closed when the level falls. Changeover of contacts occurs when level rises/falls with 15 mm liquid level differential. Significant product features include: glandless and hence leakproof, easy installation, outdoor design, no power consumption, no maintenance, etc.
