Basics of AC Induction Motors
The basic principle of an AC induction motor is that one or more out-of-phase AC (sinusoidal) currents energize sets of electromagnet coils (called stator coils or windings) arranged around the…
Pressure Gauge Syphons Principle
A pressure gauge siphon is a simple device used to protect a pressure sensor from high-temperature media, such as steam. It can also be used to reduce the potentially damaging…
Pressure Gauge Cocks
Pressure gauge cocks are intended to isolate the pressure gauge from the pressure media in order to enable inspection or replacement of the gauge where the pressure is continuously pulsating.…
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…
Pressure Gauge Snubbers
A pressure gauge snubber is a device used to suppress ("snub") excess force or rapid movement in mechanical systems. Pressure snubbers are designed to dampen the effect of pressure pulses…
Target Flow Meter – Working Principle, Advantages, Disadvantages
A target flow meter measures flow by measuring the amount of force exerted by the flowing fluid on a target suspended in the flow stream.
Motor Control Circuits
Motor control circuits are often connected to lower voltages than the motor they control to make it safer for operators and maintenance personnel.
