Abstract: A tilt sensor includes: a pressure sensor disposed to be relatively movable with respect to a detection target object and configured to detect pressure of a fluid; and a tilt information detection unit configured to detect tilt information (for example, a tilt angle) of the detection target object according to an output of the pressure sensor and movement information of the pressure sensor.

Abstract: A pressure change measuring apparatus and a pressure change measuring method are capable of detecting a change in pressure to be measured with respect to a time axis with high accuracy. The pressure change measuring apparatus includes a reference value setting unit that generates a reference value signal based on an output signal of a differential pressure measuring cantilever under a predetermined state and outputs the reference value signal. An arithmetic processing unit calculates the pressure change in the pressure to be measured based on the output signal, the reference value signal, a volume of a cavity, and a flowing quantity of a pressure transmission medium flowing into and out of the cavity for every unit of a predetermined time period.

Abstract: The present invention provides a pressure change measuring apparatus and a pressure change measuring method, which are capable of detecting a change in pressure to be measured with respect to a time axis with high accuracy. Specifically, a reference value setting unit (60) included in a pressure change measuring apparatus (1) is configured to generate a reference value signal based on an output signal of a differential pressure measuring cantilever (4) under a predetermined state, and to output the reference value signal. An arithmetic processing unit (30) is configured to calculate the pressure change in pressure to be measured based on the output signal, the reference value signal, a volume of a cavity (10), a flowing quantity of a pressure transmission medium flowing into and out of the cavity (10) for every unit of a predetermined time period, and the like.
