WORKING PRESSURE MEASUREMENT DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a working pressure measurement device having different measurement ranges in which working pressure differing in range can be measured.SOLUTION: A working pressure measurement device includes: a measurement rod 6 for measuring pressing pressure; springs compressed as the measurement rod 6 is operated so as to measure the pressing pressure; and a housing 2 which holds the spring inside, the housing 2 holding a plurality of springs 5a and 5b differing in spring constant inside. The working pressure measurement device includes a selective compression member 8 which compresses only a spring to be used for measurement between the plurality of springs 5a and 5b as the measurement rod 6 is operated.
