A relay is an electrical switch that opens and closes under the control of another electrical circuit. Electronic relay are used in a wide variety of applications throughout industry, such as in telephone exchanges, digital computers, motor and sequencing controls, and automation systems. Highly sophisticated relays are utilized to protect electric power systems against trouble and power blackouts as well as to regulate and control the generation and distribution of power. Get more information about how these electronic relay works and what important role they play.
Electrochemical sensors have electrode arrays with two, three or more electrodes, which are called auxiliary electrode. Electrochemical sensors are used to determine the concentrations of various analytes in testing samples such as fluids and dissolved solid materials. Electrochemical sensors are frequently used in occupational safety, medical engineering, process measuring engineering, environmental analysis, etc. Electrochemical sensors, such as pH sensors, ion selective sensors, and redox sensors, are equipped with electrical conductors to allow electrical signals to be transmitted to and from electrodes contained within the sensor.
Electrochemical detection is also one of the important terms related to this. The electrochemical detector responds to substances that are either oxidizable or reducible and the electrical output is an electron flow generated by a reaction that takes place at the surface of the electrodes.
An electric motor is a device that converts electric energy into mechanical energy. Electric motors are found in household appliances such as fans, refrigerators, washing machines, pool pumps and fan-forced ovens. The reverse process that of converting mechanical energy into electrical energy is accomplished by a generator or dynamo. A three phase induction motor has a simple design, inherently high starting torque, and high efficiency. Such motors are applied in industry for pumps, fans, blowers, compressors, conveyor drives, and many other kinds of motor-driven equipment. 3 phase electric motor will also vibrate less and hence last longer than single phase motor of the same power used under the same conditions.
