Title:
診断器具を備えた蒸気トラップ監視装置及び蒸気トラップの動作監視方法
Document Type and Number:
Japanese Patent JP6511395
Kind Code:
B2
Abstract:
A steam trap monitor includes a process variable sensor configured to sense a process variable related to operation of a steam trap. A memory contains information related to a baseline parameter of the process variable. Diagnostic circuitry calculates a current parameter of the process variable sensed by the process variable sensor and compares the current parameter of the process variable with the baseline parameter. Based on the comparison, the diagnostic circuitry responsively provides a diagnostic output based upon the comparison. The baseline and current parameter are based on a time period during which the steam trap is open or closed.
