What are transformers? The transformer is a static piece of apparatus which transfers electrical energy from one circuit to another, which are electrically disconnected by means of mutual induction. A Transformer consists of two or more stationary electric circuits where the source…
DIFFERENCE BETWEEN DCS ,PLC AND SCADA SCADA (Supervisory contol and Data Acquisition) is essentially a computer based (usually PC nowadays) system for displaying field data. The difference between it and HMI (Human Machine Inerface) software aren’t significant.Most SCADA systems are tag based, and a lot of…
Load cells are transducers that are used to convert work, force or pressure into an electrical signal. Load cells are also called as load transducer or load sensors. The force is measured on the basis of deflection or increase in fluid pressure. There…
Introduction The encoders use rotating discs with optical windows, as shown in the figure below. The encoder contains an optical disk with fine windows engraved on it. The light from the emitters goes through the openings in the disk to the detectors….
Introduction There are two basic counter types: count-up and count-down. When the input to a count-up counter goes true the accumulator value will increase by 1 (no matter how long the input is true.) If the accumulator value reaches the preset value the…
Introduction This function is used to provide a time-delay in a circuit. In the example shown in figure, a switch-off delay is used to delay the off-time. The lamp P1 will be off after 5 seconds.An ON delay timer will wait a…
Introduction In this session we are gonna discuss about troubleshooting of a transmitter.we are gonna look into some common problems and their solutions . What are the troubleshooting when Transmitter milliamp reading is zero Verify power is applied to signal terminals Check…
Slide valves are one of the many variations of the gate-type valve and were originally designed for use in the pulp and paper industry to overcome the problems in handling wet and dry fluidized solids in pipelines. The opening…
Noise produced in pipelines may be pump-generated (changes in power and pressure. or varying amplitudes of pressure pulsations) or fluid-generated (flow instability, turbulence or simple fluid friction). Noise caused by the operation of valves, regulators and control elements is transient and related…
Introduction As you can see we already discussed about some of the Installation & Troubleshooting of some communication systems in part 1 this section will discuss about AS-i,devicenet, ethernet,TCP/IP if you want to read about part 1 link is given below Part 1…
