What is DeviceNet? DeviceNet is a low-cost communications link for connecting industrial devices as inductive sensors, photoelectric, limit switches, push buttons, barcode readers, indicator lights, operator interfaces, motor controllers, etc., to a network, avoiding costly and complex wiring. DeviceNet brings LAN technology…
Industrial networking is the key function to process control. it should be recognized that that networking goes beyond the interfacing of factory systems, to interface with design and documentation systems to form a virtual organisation and other related systems. The actual selection of…
Ultrasonic Proximity sensor: The ultrasonic proximity sensor uses a transducer to send and receive high-frequency sound signals. If the incoming target sound range is reflected again to the sensor, causing the sensor to activate or not activate the output circuit. Piezoelectric…
Reed switch is also called an inductive-magnetic sensor, so it is grouped in special inductive sensors. Reed switch is printed in a bakelite box. If the switch enters a magnetic field, the contact feathers become closed, and the sensor provides electrical signals….
In the case of a rotating shaft, the most widely used method of support is by using one or a number bearing. A considerable number of different types of bearings are commonly available. The system selected is a function of the loads…
Parallel plate interceptor (PPI), Corrugated plate interceptors (CPI) are Plate coalescers. Plate coalescers are skim tanks or vessels that use plates used to increase the process of gravity separation. Various forms of coalescer plate have been found. Parallel Plate Interceptor (PPI) The first…
A Gas turbine is also called a combustion turbine is a type of continuous combustion, internal combustion engine which produces electric current. The gas turbine can operate using two types of fuel (dual fuel system) namely natural gas and oil, can also be operated…
The methods used for measurement of medium resistances are not suitable for measurement of low resistance. This is due to the fact that resistances of leads and contacts, though small, are appreciable in comparison to the low resistances under measurement. Voltmeter–Ammeter Method…
The instruments used to measure the physical and electrical quantities are known as measuring instruments. The measuring instruments may be classified as follows: Absolute instrument & Secondary instruments: Absolute instrument measures the process variable directly from the process without the use of conversion. Such…
Why sensors are used in process industry? Automation devices used for the realization of control techniques from a process such as hardware, PLC software or microcontroller can only run well if the required process data can be obtained validly, for example information such…
