New Sump Pump Float Working Principle

  • When the cooling tower stops using the water for its industrial operations, the water level starts to rise. ...
  • When the water level reaches the probes, a signal is transferred between the probes informing the high alarm to activate.
  • When the high alarm is activated it can be programmed to tell the fill to stop filling up the water.

A sump pump float switch detects flooding in the sump; it's what turns your sump pump on and off in response to the amount of water in the sump pit. The device relies on a round float ball to measure liquid level, like a beach ball that floats on top of the water. When the water rises, the float rises with it.Nov 8, 2016

The holding relay eliminates pump chatter in turbulent conditions, allowing the Double Float® pump switch to operate relay control panels for larger pump applications.

How does a sump pump control switch work?

The digital level control switch relies on water pressure increase in the sump basin. When the water level rises in the sump pit, the increased water pressure causes electrons to move through the electronic component. The electronic board handles the high initial current. While the current levels out; then a timed relay takes over and turns on the switch which activates the sump pump motor to run. At the end of the relay timed period, the switch turns off and the pump turns off as well. The water level in the pit has lowered as well as the water pressure. As the water pressure builds again, the entire process is repeated again and again.

How does a float switch work?

The tether float switch and the vertical float switch depend upon the movement of the float to trigger the switch which activates the sump pump motor. As the water level increases in the sump pit, the float rises. When the float is raised high enough by the water, the switch is triggered and the sump pump motor turns on. When the float lowers enough because the sump pit water lowers, the switch turns off the pump.

What is the function of the diaphragm switch?

The diaphragm switch depends upon a membrane to sense the amount of water pressure in the sump pit. As the water level rises, the water pressure increases; the diaphragm (membrane) becomes concave and consequently activates the switch which turns on the sump pump motor. When the water level lowers, the membrane becomes convex and the switch turns off; the sump pump stops running.

What causes sump pump float switches to fail?
