APPLICATIONS

Liquid level control switch, ALLCS500MA45-21, is

designed for sensing the liquid levels found in water

containers, ponds, fish tanks, etc. It is widely used in

household appliances (such as: water machine, water

dispenser, humidifier, dehumidifier, water heater, air

conditioning, direct drinking water system, etc.), industrial

equipment (such as: air hydraulic machine, cooler, drainage,

lubricating oil system), gardening equipment, medical

equipment, beauty salon equipment, aquatic farming and

industrial water purification, sewage treatment systems,

automatic door control system and other industries.

DESCRIPTION

The liquid level control switch, also called the water level

control switch or liquid level sensor, is to control the liquid

level. ALLCS500MA45-21 is a small stainless float type

liquid level control switch. This liquid level control switch

features small size, high sensitivity, high temperature

resistance, oxidation resistance, moisture proof, etc.
