How to Get the Best Price for Quality Products
Instrumentation and process control are two terms that are often heard in the same sentence. This is because they go hand in hand. Instrumentation is the measurement of process variables, while process control is the use of these measurements to maintain a desired output. In order to get the best price for quality products, it is important to understand how instrumentation and process control work together. At LKI.no you can check more information about this topic.
The first thing to understand is that instrumentation and process control are not the same thing. Instrumentation is the collection of data, while process control is the use of that data to make decisions. In other words, instrumentation is the foundation upon which process control is built.
Instrumentation can be divided into two categories: input and output. Input instruments are used to measure variables such as temperature, pressure, level, and flow. Output instruments are used to provide a signal that can be used to control a process variable. For example, an output instrument could be used to turn on a heater when the temperature falls below a certain point.
Process control can be further divided into two types: feedback and feedforward. Feedback controls use measurements from input instruments to make adjustments to the process. For example, if the temperature of a reaction is too low, a feedback controller could turn on the heater. Feedforward controls use measurements from output instruments to make adjustments to the process. For example, if the level of a tank is getting low, a feedforward controller could open a valve to allow more liquid into the tank.
