PIPING PROBLEM SENSING DATA LOGGER, PIPING STRUCTURE, AND PIPING PROBLEM SENSING SYSTEM

摘要

A piping problem sensing data logger that acquires vibration data of high quality and improves the accuracy of problem sensing because the installation method can be standardized and that reduces the risk of being detached from piping and the possibility of being lost after someone detaches it because it can be stationary-installed. The piping problem sensing data logger (1) includes a bolt portion (10) and an antenna portion (13). The bolt portion (10) includes a bolt head portion (12) and a bolt thread (11). The antenna (13) is disposed on an opposite side of the bolt head portion (12) from the bolt thread (11) or disposed in the bolt head portion (12). The bolt head portion (12) includes a vibration detection element (121), a memory unit (122), a control unit (123), a wireless control unit (124), a clock device (125), and a power-supply device (126).
