Introduction:Instrument insulation boxManufacturing technology is constantly improving, especially with the introduction of microelectronics technology. Many instruments have become fully electronic, with no moving parts, and analog instruments have been replaced with digital instruments. Therefore, the indicator of deterioration is not as important and prominent in intelligent instrument insulation boxes.
Sensitivity refers toInstrument insulation boxThe sensitivity to changes in the measured parameters, or in other words, the ability to respond to changes in the measured quantity, is the ratio of the output change increment to the input change increment in steady state. Sensitivity is sometimes also known as the 'amplification ratio' and is the slope of each point on the tangent line of the static characteristics of the instrument insulation box. Increasing the amplification factor can improve the sensitivity of the instrument. Simply increasing the sensitivity does not change the basic performance of the instrument insulation box, that is, the accuracy of the instrument insulation box does not improve. On the contrary, sometimes oscillation occurs, causing unstable output. The sensitivity of the instrument insulation box should be maintained at an appropriate level.
However, forInstrument insulation boxFor users, such as instrument workers in chemical enterprises, the accuracy of instrument insulation boxes is certainly an important indicator, but in practical use, the stability and reliability of instrument insulation boxes are often emphasized more, because there are not many detection and process control instruments used for measurement in chemical enterprises, and a large number are used for testing. In addition, the stability and reliability of the instrument insulation box in the process control system are more important than accuracy.
