摘要
A pressure transmitting device detects, through a pressure guiding tube, a pressure of a liquid, slurry, gas, or the like to be measured, wherein there are fluctuations in the pressure; where the pressure guiding tube blockage diagnosing device comprises: a rising/falling frequency detecting portion for segmenting into a plurality of continuous intervals a time series of pressure values detected by the pressure transmitting device, and for detecting, in each time interval, the rising/falling frequency of the fluctuations; and an evaluating portion for evaluating the state of blockage of the pressure guiding tube through comparing, to a specific threshold value, the rising/falling frequency of the fluctuations.
