Float switch P140-43NBR

Liquid level sensing switch is a liquid level control device has the advantages of simple structure, convenient use, safety and reliability, the general received relays or contactors, and then through the relay / AC contactor control other motors, electrical appliances.... When the water level, level up / down to a certain distance, the inductive switch is closed or cut off, with the relay / AC contactor also follow closed or cut off, so as to control the water level, water pump, oil level.

It can be through the voltage is 3--350V (AC / DC), so the voltage is connected with the 220V is possible! But its power is very small! (rated current conventional is 0.5A), so you can't let it directly with the electrical components than its big power, going through the relay / AC contactor: liquid level switch rated current of 0.5A, can be used within a 10A relay.

Its small size / lightweight, fast speed, environmental non-toxic, acid and alkali resistance, corrosion resistance, high temperature and high pressure resistance, simple structure, convenient installation, low cost, high sensitivity and accurate and reliable operation, is not affected by the fluctuation of water level effect, long service life, remote control. Compared with the electronic switch, it also has the characteristics of anti load impact ability, in the humidification machine, wet grinding machine, water machine, water heater, water heater, water purifier, cleaning machine, solar energy, air conditioning, bathroom equipment and other household appliances; aspects of oil tank, water tower, chemical liquid level control of shipbuilding, paper etc. and printing, generator equipment, petroleum chemical industry, food industry, water treatment, electrician, dye industry, hydraulic machinery, laboratory equipment and so on various equipment level control system has been widely applied.
