<P>PROBLEM TO BE SOLVED: To detect clogging of a pressure connecting pipe at an earlier time point by improving sensitivity of diagnosis of clogging in the pressure connecting pipe. <P>SOLUTION: A container 10 is connected to a pressure connecting pipe 3 in the vicinity of a connecting point between a process piping 2 and a pressure transmitter 1. Accordingly, if a fluid 7 is a compressible fluid, a deformation ratio of the fluid 7 increases with respect to changes in pressure, changes in pressure fluctuation are easily detected, and the sensitivity of diagnosis of clogging in the pressure connecting pipe is improved. If the fluid 7 is a non-compressible fluid, a component having a diaphragm (pressure receiving surface greatly deformed by pressure) is connected instead of the container 10. <P>COPYRIGHT: (C)2013,JPO&INPIT |
