| Product Introduction
The WCLL300 series miniature float-type level switch developed and produced by winchen sensor is a level detection product designed specifically for small spaces and small liquid containers. It works on the principle that the float follows the liquid level up and down to trigger a reed switch; when the level reaches the set height, a switch signal is output to achieve level alarm, water shortage protection or automatic water replenishment control.
The WCLL300 series miniature float-type level switch is compact in size and structure and simple to install - vertical installation is all that is needed. The product supports both normally open (NO) and normally closed (NC) signal outputs, and cable length, terminals, float material and so on can be customized according to actual needs. It is widely used in water purification equipment, new energy equipment, medical equipment, water treatment equipment, hydraulic machinery, small industrial liquid storage devices and other fields.
| Features
1. Compact size, saves installation space: compact design, suitable for installation inside equipment with limited space.
2. Sensitive action, precise level control: the float quickly triggers the reed switch as the level changes, with high repeat accuracy and stable, reliable level control.
3. NO/NC selectable, compatible with various control circuits: normally open or normally closed output can be selected according to control requirements, easy to connect to different control systems.
4. Multiple material options, compatible with different liquid media: float and stem material options including PP and stainless steel, suitable for clean water, weak acids and alkalis, and some industrial liquids.
5. Simple structure, long service life: no complex mechanical transmission parts, good sealing performance of the reed switch, not prone to failure in long-term operation.
6. Easy installation, low maintenance cost: vertical threaded or snap-in mounting; simple installation and replacement, reducing equipment maintenance costs.
7. Flexible customization, stable lead time: supports customization of cable length, terminals, wire harness, float material and other parameters to meet volume application needs.
