Star Encyclopedia : Principles for the Selection of Automated Instrumentation

In the process of industrial production, instrumentation plays an important role in detecting, displaying, recording or controlling process parameters. The detection of the process production process is the basic means to understand and control industrial production, only at any time can accurately understand the whole picture of the process, and control, in order to ensure the smooth production process, and with high productivity, small consumption to produce qualified products. That’s why automated instrumentation becomes indispensable. So how to choose the right automation instrumentation. First, the conditions of the process The temperature, pressure, flow, viscosity, corrosiveness, toxicity, pulsation and other factors of the process are the main conditions for determining the selection of the instrument, which is related to the rationality of the instrument selection, the service life of the instrument and the fire prevention, explosion-proof, security and other issues of the workshop. Second, the importance of operation The importance of the parameters of each detection point in operation is the basis for the selection of the indication, recording, accumulation, alarm, control, remote control and other functions of the instrument. Generally speaking, variables that have little impact on the process, but need to be monitored frequently, can be indicative; For important variables that need to be constantly informed about changing trends, the record format should be chosen; Some variables that have a greater impact on the process and need to be monitored at any time should be controlled; For variables that are related to material balance and power consumption and require measurement or economic accounting, it is advisable to set up an accumulation; For some variables that may affect production or safety, it is advisable to set alarms. Third, economy and unity The selection of instrumentation is also determined by the scale of investment, and the necessary economic accounting should be carried out under the premise of meeting the requirements of process and automatic control, so as to obtain the appropriate performance and price ratio. In order to facilitate the maintenance and management of instrumentation, attention should also be paid to the uniformity of instrumentation when selecting models. Try to choose products of the same series, the same specification and the same manufacturer. Fourth, the use and supply of instruments and meters The selected instrumentation should be a relatively mature product, which has been proven to be reliable in the field; At the same time, it should be noted that the selected instruments and meters should be in abundant supply and will not affect the construction progress of the project.
