What is Three Phase? A typical technique of alternating-current electric power generation, transmission, and distribution is three-phase electric power. It is a form of polyphase system that is utilised by electrical grids all over the world to transfer power. Large motors and other heavy loads are also powered by it. Because it utilises less conductor …
For most control applications in process industries, it is required to have more than one control valve to respond to the single controller output. The control valves must be configured to follow the control instructions issued by a particular controller. Control valves are said to be split ranged or sequenced and configured to follow the …
Modes of Split-Range Control in Control Valve Applications Read More »
Control valves are constructed using various combinations of the valve actuator and valve body. The failure modes in the control valve actuator is achieved by combining direct acting or reverse acting actuator and direct acting or reverse acting valve body. The selection of valve actuator and valve body is done in such a way to …
What is Two Phase? Two-phase electrical power was an optional process (polyphase) alternating current electric power distribution technology used in the early twentieth century. Two circuits were employed, with voltage phases that differed by a quarter of a cycle, or 90 degrees. Typically, four wires were utilised in circuits, two for each phase. Three wires were …
What is an ELCB? Earth Leakage Circuit Breakers are safety devices that provide additional protection against earth leakage. ELCB is employed in places where the earth impedance is high. The primary objective of these devices is to reduce the risk of shock in the event of a current flow to the earth. When energy “leaking” …
What is Circuit Breaker? A circuit breaker is a device that may manually or automatically break a circuit under all circumstances, including no load, full load, and short circuit. A circuit breaker is a device that can perform any of the following functions: Under typical circumstances, manually or by remote control, makes or breaks a …

What is a stepper motor? A stepper motor is also called a step motor because it is a pulse-driven motor that would change the angular position of the motor in steps. The stepper motor would rotate at a specific angle of degree according to the electric pulse. Basically, it is a brushless synchronous electric motor …
The pressure sensor and pressure transmitters are very useful instruments for the measurement and controlling of pressure in process industries. The pressure gauge is used for local indication and transmitters & pressure switches for controlling a process. And these instruments need to be calibrated for any errors. For this, we require a pressure calibrator to …

Temperature measurement and control is an important factor in all process industries and in power plants environments of higher temperature and higher pressure. The thermowell allows the temperature sensor Thermocouple and RTD to remove easily from the process environment for the purpose of calibration in case of measurement error, or replacement in case of …
