Mechanical Vibration Switch Principle

S Bharadwaj Reddy
Mechanical Vibration Switches provide vibration protection for low- to medium-speed machinery. An inertia sensitive mechanism activates a snap-action switch with SPDT output contacts if the vibration exceeds an adjustable setpoint.

Speed Probe Working Principle

S Bharadwaj Reddy
Rotating machinery requires speed sensing for functional systems such as control, monitoring, and safety. To ensure safe operation, it is especially important to monitor rotor speeds in turbine engines. Inductive

Vibration Switch Working Principle

S Bharadwaj Reddy
What is a vibration switch? A vibration switch is a device that recognizes the amplitude of the vibration to which it is exposed and provides some sort of response when

How Vibration sensors Work ?

S Bharadwaj Reddy
Sensors used to measure vibration come in three basic types: displacement, velocity, and acceleration. Displacement sensors measure changes in distance between a machine’s rotating element and its stationary housing (frame).
