Types of Level Switch's

A Level Switch is an instrument for monitoring the height of liquid and tripping relay contacts

This Switch  may used for a Indication or to control a pump.

There are different types of level switch with different working Principles. Level Switch used widely in every industries for monitoring and controlling level.

In this article, we just discuss the type of level Switch's.

Capacitance Type Level Switch 

This type of switch detect the level by changing its capacitance.

Capacitance Type Level Switch 

Optical Type Level Switch

Optical level switch Works on principle of Reflection

Optical

Conductivity Type Level Switch

Conductive material touches the electrodes, a AC current starts to flow which operates the relay in the control.

Conductivity

 Float Type Switch level switch

This types of switch's works on buoyancy force

Vibrating Tuning fork Type Level Switch

Vibrating tuning fork liquid level switches are threshold contact trip devices which typically consist of a tuning fork which extends out from the switch housing
