Title:
PRESSURE GAUGE
Document Type and Number:
WIPO Patent Application WO/2016/016912
Kind Code:
A1
Abstract:
[Problem] To provide a pressure gauge that allows the presence of a measurement error to be readily checked. [Solution] This pressure gauge includes a piston; a first conversion mechanism that converts linear motion, generated by the pressure from an object to be measured, against the elastic force of a spring of the piston into rotational motion about a first rotation shaft; an indicator needle that is fixed to one end of the first rotation shaft; a dial; a momentum detecting means for detecting momentum indicating the amount of movement of the piston; and a pressure sensor that measures a pressure value of the pressure exerted in an internal space in the cylinder. A determination means determines whether or not the difference between a first measurement value estimated from the momentum detected by the momentum detecting means and a second measurement value measured by the pressure sensor exceeds a predetermined value. If the difference between the first measurement value and the second measurement value exceeds the predetermined value, a notification is given to a user by a notification means.
