Flow Switch : What is it ?
Flow Switch is a mechanical switch that is switched on or off in response to the flow or non-flow of a fluid such as air or water. The switch typically operates
What is a Limit Switch ?
Limit Switch is a switch operated by the motion of a machine part or presence of an object. They are used for control of a machine, as safety interlocks, or to
What is a Inductive Proximity Switch ?
Inductive Proximity Switch is a device which causes a switching action without physical contact. Inductive Proximity Switches respond to targets that come within the active range of their generated sensing
Belt Sway Switch Working Principle
The belt sway switch allows smooth running of the conveyor and protects it from damages by over swaying which can occur due to uneven loading of material, worn out idler
Pull Cord Switch Working Principle
Pull Cord Switch is an emergency switch to stop the belt conveyor instantly when an accident happens. Since the Pull Cord Switch is so designed that it should be installed
Safety Switches for Controlling Conveyor Operations
In the process to produce cement, power, steel, aluminum etc. , raw material and other inputs have to be transferred from mines or receiving stations to the point of processing.
Electromagnetic and Conductive limit switches Principle
Electromagnetic Limit Switch The electromagnetic wave measuring process allows for universal use even when the media changes. The electromagnetic wave penetrates the medium and, depending on the respective relative permittivity,
What is Contact bounce ?
When a switch is actuated and contacts touch one another under the force of actuation, they are supposed to establish continuity in a single, crisp moment. Unfortunately, though, switches do
RF Capacitance Level Switch Working Principle
RF-Capacitance /Admittance level switch consists of a guard section, upper insulation, main probe and grounding. The guard section is designed to overcome possible medium attachment and to secure signal accuracy.
