Title: Operation frequency detector of steam trap
Inventor: NAGASE MAMORU
IPC: F16T1/48
Filed: 1990-02-15
Abstract: PURPOSE:To prevent the erroneous counting of drifts and the judgment of a normally operating one as a defective by comparing the average value of a plurality of data at the time of arithmetic processing of operation frequency of the opening and closing valve of a steam trap. CONSTITUTION:When the frequency of opening and closing valve operation of a steam trap 12 is detected 10 as electric vibrations for arithmetic processing 14, the maximum value and minimum value of drifts are calculated from the average value of a plurality of sampling data up to the last time, and when the average value of a plurality of following sampling data is the maximum value of drift of the average value of the sampling data up to the last time or more, and flag is OFF, the operation frequency is counted. The operation frequency is judged from the count numbers of the both. Hence, the drift width in a drift part can be reduced. Thus, even when the thickness of a casing is thin, and the pressure of a steam pipeline system is high, the drift is never detected as the operation frequency, and a normally operating one is never judged as a defective.
