Horizontal-Mount P.P Float Level Switch LS06

MISENSOR Fluid Controls will get you the right float switch or liquid level sensor for your application! Whether you need an off the shelf float switch or a custom designed liquid level sensor, we can help! Strain Measurement Devices is a technically driven design and manufacturing firm dedicated to helping customers solve their toughest sensor and measurement problems. KAIDI's talented staff has been designing custom sensors to measure force, pressure, temperature, weight, torque, liquid level and many combinations.

MISENSOR Fluid Controls can design and manufacture a custom or standard float switch or liquid level sensor in many shapes and materials. Whether you desire an inexpensive plastic float switch or a rugged stainless steel multi level liquid sensor, let use guide you to the proper solution. You can submit your project on line by selecting the customize button next to the float switch product that best meets your needs, and an engineer will contact you to finalize any required details. Our on line application notes may also be used to let you design your own cost effective float switch pump control.

For customers who demand replacement parts or a customized float switch or liquid level sensor, we offer competitive pricing for OEM designs and applications. We can also design a machined level sensor or custom molded float switch in a large variety of metals or plastics.

When the float ball rises or falls with the liquid to the level of the switch, The magnetic force of magnet which inside of the float ball will cause the reed switch to turn ON. When the float ball move away from the reed switch, the reed switch will turn OFF.

It can reversible from NO to NC (Normally open or Normally closed)

open or close a circuit with only a small change in liquid level - usually a 1/4" to 1/2" movement in level will change the status from open to closed or vice-versa. Where it is desirable to turn a device on at one level and off at a significantly higher or lower level, two float switches can be used.

Suppose that you want a pump to fill a chamber to the point where it is 75% full. You do not want the pump to begin refilling the chamber until the liquid level has dropped to the point where it is only 50% full. The difference in these two levels is 6 inches. Since a float switch activates in about 1/4"-1/2", using a single float switch will not achieve your objective.

The solution is achieved by using two normally-closed float switches. The illustration below shows a simple way to utilize a standard, inexpensive eight prong DPDT relay to prevent the bottom switch from opening the pump circuit and prevent the top switch from closing the circuit. Using this arrangement, the float switches can be placed at any desired "turn pump on" and "turn pump off" levels.

The above illustration is for a "fill-up" application, but the same logic can be utilized in a "drain-out" application. In such an application a pump would be used to pump liquid out of a chamber when it was 75% full and continue pumping liquid out until the level was reduced to 50% full.

You can achieve this by inverting both switches and reversing their position - i.e. the switch shown in the upper position in the illustration would instead be placed low in the chamber where the pump should turn on; likewise, the switch shown in the lower position in the illustration would be placed high in the chamber where the pump should turn off. Remember to invert each switch so that it acts as a normally-open rather than a normally-closed switch.
