With the development of industrial automation, there are more and more types of instruments, and today we will introduce to you the basic principles of instrument selection. First of all, we need to consider the conditions in the industrial 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. Secondly, 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 the instrument is also determined by the scale of investment, and the necessary economic accounting should be carried out to obtain the appropriate performance/price ratio under the premise of meeting the requirements of process and automatic control. In order to facilitate the maintenance and management of the instrument, it is also necessary to pay attention to the uniformity of the instrument when selecting the instrument. Try to choose products of the same series, the same specification and the same manufacturer. Finally, the use and availability of meters. The instrument selected 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 instrument should be in abundant supply and will not affect the construction progress of the project. Production-oriented instrument enterprises have a reliable guarantee for the technology, type and supply of instruments, which provides a diversified choice for industrial automation.
