Title:
PRESSURE SENSOR
Document Type and Number:
WIPO Patent Application WO/2016/170743
Kind Code:
A1
Abstract:
This pressure sensor is provided with a sensing unit (10) that outputs a detection signal corresponding to pressure; an amplifying unit (30), which amplifies the detection signal at a predetermined amplification factor, and outputs the signal as a pressure signal; a determining unit (40); and a signal output unit (60). The determining unit (40) determines, on the basis of determining reference, whether the signal value of the pressure signal is a value of lower pressure with respect to a reference value at which a pressure detection range is halved. In the cases where the determining unit (40) determines that the signal value of the pressure signal is not a value of the lower pressure with respect to the reference value, the signal output unit (60) outputs a determination signal indicating that the signal value of the pressure signal is not a value of the lower pressure with respect to the reference value.
