What is Contactor ?
To start up and shut down a three-phase AC induction motor, any three-pole switch with a suitable current rating will suffice. Simply closing such a switch to send three-phase power

How Tilt Level Switch Works ?
Tilting type level switch so designed to be hung in the tank with a stainless chain. When the switch inclines above 20 degrees owing to the increase of stored material,
Load Cell Working Principle
Load cell is a sensor or a transducer that converts a load or force acting on it into an electronic signal. This electronic signal can be a voltage change, current
Ultrasonic Sludge Blanket Level Meter Animation
Sludge Level Probe uses an ultrasonic pulse to accurately measure the sludge level. An ultrasonic signal sent from the probe is directed towards the sludge blanket in the tank. Height
Coriolis Mass Flow Meter Working Principle
Mass flowmeters are the types of flowmeters which are mainly employed in mass-related processes such as chemical reactions, heat transfer, etc. In all these processes, accurate measurement of flow is
Working Principle of Vortex Flow Meter
Vortex Meters can be used for a wide range of fluids, i.e. liquids, gases and steam. They are to be seen as first choice, subject to verification to cover the
Thermal Mass Flow Meter Working Principle
Principles of Operation Thermal mass flow meters employ the thermal dispersion principle whereby the rate of heat absorbed by a fluid flowing in a pipe or duct is directly proportional
Oval Gear Flow Meter Working Principle
Oval gear flow meters are traditional, mechanical, positive displacement (PD) flow meters, first invented more than 50 years ago by OVAL Corporation of Japan and now widely used for flow
Eddy Current Working Principle Animation
Eddy currents are currents induced in conductors, when a conductor is exposed to a changing magnetic field due to relative motion of the field source and conductor; or due to
Displacer Level Switch Working Principle
Displacer controls offer alternative features to the float-operated control. The sensor is a weight (displacer), heavier than the liquid, that is suspended by a spring. When liquid contacts the displacer,
