What are thermostats? The thermostat is a device for adjusting the temperature of the system so that the system temperature is maintained near the desired setpoint temperature.  The thermostat does this by switching the heating or cooling or deactivating the device or adjusting the fluid flow of heat transfer needed, to maintain the correct temperature. A …

Functions of DCS: Based on its function, DCS has functions: DCS functions as a tool to control a loop system where one loop can perform several control processes. Serves as a substitute for manual and automatic control devices that are separated into a unit so that it is easier to maintain and use Data collection …
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 an industrial network is based on a number of criteria including: The detailed …
Advantages of the Hydraulic system: When compared to the mechanical power method has a weakness in the placement of the transmission power position. It is different with hydraulic power hydraulic power lines can be placed in any place. Regardless of the position of the shaft to the power transmission as in the mechanical power …

Components of automated system: The automatic system includes the following components: Operation Workstation Consists of Workstation Operators computers for …
It is a data communication that aims to reduce or prevent failure in several loops. This results in the failure of a loop to affect the other control loops. The use of Fieldbus also functions as savings on cable routing because the addressing system carried out by Fieldbus allows many devices to communicate via one …
Inverse Time Circuit Breakers Inverse time circuit breakers have both thermal and instantaneous trip features and are preset to trip at standardized levels. This is the most common type of circuit breaker used in the building trades for residential, commercial, and heavy construction. The thermal action of this circuit breaker responds to heat. If a …
Profibus ProfiBus (PROcess FIeld BUS) is a widely accepted international networking standard, commonly found in process control and in large assembly and material handling machines. It supports single-cable wiring of multi-input sensor blocks, pneumatic valves, complex intelligent devices, smaller sub-networks (such as ASi), and operator interfaces. It is an open, vendor independent standard. It adheres …

Industrial safety system An industrial safety system is a countermeasure crucial in any hazardous plants such as oil and gas plant sand nuclear plants. They are used to protect human, plant, and environment in case the process goes beyond the control margins. As the name suggests, these systems are not intended for controlling the process itself …
Introduction The majorities of the instructions take two input values, perform the specified arithmetic function, and output the result to an assigned memory location. For example, both the ADD and SUB instructions take a pair of input values, add or subtract them, and place the result in the specified destination. If the result of the …
