LR-S2 Series Float Level Switch
Suitable for measuring liquid levels—whether top-mounted or side-mounted—the float rises and triggers a contact action, converting the measured liquid level into a switch signal output. This allows for local audible and visual alarms or remote monitoring. The product features the following characteristics:
● Suitable for sealed tanks
● The reed switch contact material is rhodium (with a surface layer of rhodium oxide), offering a contact life of up to 2 million cycles.
● The special treatment of the reed switch enables it to operate normally even at high temperatures of 200°C.
● Multiple control points can be implemented, and the position of each control point can be customized according to customer needs.
● All the outgoing wires from the switches are concentrated inside the junction box, making installation simple and convenient while reducing wiring costs.
● The junction box has an IP65 or higher protection rating and can be configured with intrinsically safe or flameproof types as needed.
● Overall performance is reliable. Materials available include SUS304, SUS316L, PP, PVDF, PTFE, and more.
● Length can be custom-made to any size (Lmax ≤ 5m)
