智能测量系统的发展要求仪器能够提供高质量的测量信号。这意味着，最初的重点应放在确保测量系统的完整性上。这也意味着，除了被测信号外，测量系统还应提供其运行状态以及相关设备的运行状态的指示。当怀疑设备内存在故障或故障条件时，需要条件信号来验证被测信号。本文是IMTC93论文（1993年5月）的延续。这里介绍了对压力和差压测量系统进行研究的其他结果。重点是分析商业上可用的压力和压差测量系统的传统输出信号中的噪声，以检测过程连接中的堵塞。<<ETX>>
Current developments in intelligent measurement systems demand that the instruments should be designed to provide measurement signal of high quality. This implies that initial emphasis should be placed on ensuring the integrity of the measurement system. This also means that, in addition to the measurand signal, a measurement system should provide an indication of its operational status, as well as that of the associated plant. The condition signals are necessary to validate the measurand signal when there is suspicion of malfunction or fault conditions within the plant. This paper is a continuation of the IMTC93 paper (May 1993). Here additional results of studies carried out on pressure and differential pressure measurement systems are presented. The focus is on the analysis of the noise in the conventional output signals from commercially available pressure and differential pressure measurement systems to detect blockages in the process connections.<<ETX>>
