[PID] FundamenInstrumentation and process control can be traced back many millennia. Some of the early examples are the process of making fire and instruments using the sun and stars‚ such as Stonehenge. The evolution of instrumentation and process control has undergone several industrial revolutions leading to the complexities of modern day microprocessor-controlled processing. Today’s technological evolution has made it possible to measure parameters deemed impossible only a few years ago

highlighted the inconsistent results of statistical process control routinely faced by Quality Control Managers. Product weight readings were taken from the manufacturing floor‚ entered into an Excel spreadsheet and analyzed. The results produced no predictable under or over filling trend despite the fact that the same people used the same scales at the same time of day. The problem is simple and fundamental. Human error is an inevitable part of the process of collecting statistical data. This is consistently

B1 – Ethics‚ fraud and internal control at Bern Fly Company The main purpose that a good internal control must fulfil is to protect the firm’s assets from fraud and theft. As we can see from the description of Bern Fly Company’s case‚ the internal control within the company leaves much to be desired. As it can be read in the case the salespersons get commission promptly after each order taken by their customers without any control to check if that order is real or only a fictitious one. This

speed control device confined with a Bluetooth and will be given I.P. address to the Bluetooth as per their registration. And Bluetooth will be installed at every speed-limit board and will have individual I.P. address described by the National Highway Authority of India (NHAI). Bluetooth will be programmed with the speed limit as prescribed in the speed-limit board. Then this Bluetooth will interact with the Bluetooth in vehicle and will order it to control the speed using the speed control device

Control Charts Control Charts are use to distinguishes between specialcause or common-cause of variation that is present in a process. There are two basic types of control charts:- Variables - Quantitative data (Measured) Attributes - Qualitative data (Counted) Variable Control Charts Use actual measurements for charting Types:- Average & Range charts Median & Range charts Average & Standard deviation charts Individual & Moving Range charts Run Charts Attribute

Cascade control is a powerful extension of conventional 3 Cascade control is a powerful extension of conventional 3-term feed term feed back - control control. It is a strategy which compensates for specific disturbances at source and largely Prevents them from affecting process being controlled. A cascade control scheme has two controllers‚ the output of the master controller being used to adjust the set point of the slave controller The effect of steam pressure disturbances can be compensated
