    Abstract: The present invention discloses a signal processing device, an air pressure sensor assembly and an electronics apparatus. The signal processing device for a sensing signal comprises: an input unit, which is configured to receive the sensing signal; and a processing unit, which is configured to attenuate a higher frequency component of the sensing signal so that the value of the higher frequency component when the sensing signal is stable is lower than that when the sensing signal is changing. According to an embodiment of this invention, the present invention can reduce the noise in a sensing signal from an air pressure sensor during a stable state.

    Abstract: A pressure gauge includes: a pressure sensor; a display unit configured to display a measurement value of the pressure sensor; and a measurement controller configured to set, as a measurement range of the pressure sensor, any of a plurality of measurement ranges defined by a lower limit value specific to the pressure sensor and respective upper limit values that are equal to or lower than an upper limit value specific to the pressure sensor and are different from each other, and to avoid that the display unit displays the measurement value when the measurement value exceeds a display upper limit value dependent on the upper limit value of the measurement range that is set.

    Abstract: A technique for setting offset of a hydraulic pressure sensor which senses operation oil pressure is provided herein. In particular, ignition-off is detected and an ignition-off time point and remaining pressure of the object to be sensed are stored. The remaining pressure is sensed by the hydraulic pressure sensor at the ignition-off time point and stored accordingly. Additionally, whether an ignition is turned on or not after the ignition-off is also detected and an ignition-on time point is stored, when the ignition-on is detected after the ignition-off. A time lapse between the ignition-on from the ignition-off time point is then calculated along with the reduced pressure corresponding to the time lapse due to the time lapse. As a result, a value obtained by subtracting the reduced pressure from the remaining pressure of the hydraulic pressure sensor is set and applied as the offset of the hydraulic pressure sensor.

    Abstract: A pressure gauge of which the presence or absence of a measurement error can be easily checked is provided. A pressure gauge includes: a piston; a first conversion mechanism converting a linear motion of the piston against an elastic force of a spring into a rotating motion about a first rotation shaft, the linear motion being caused by the pressure transmitted from a target to be measured; an index that is fixed to one end side of the first rotation shaft; a dial; momentum detecting means for detecting momentum indicating an amount of movement of the piston; and a pressure sensor measuring a pressure value or the pressure acting on the internal space of the cylinder. Determining means determines whether a difference between a first measurement value and a second measurement value exceeds a predetermined value, the first measurement, value being estimated from the momentum detected toy the momentum detecting means, the second measurement value being measured by the pressure sensor. Notifying means notifies a user if the difference between the first measurement value and the second measurement value exceeds the predetermined value.

    Abstract: A system and method compensate for effects of gravity on the diaphragm of a capacitance diaphragm gauge (CDG). The CDG generates a measured absolute pressure value in response to an applied absolute pressure on an input of the CDG. The CDG is subjected to a variable orientation of the CDG with respect to the earth's surface that can cause inaccurate pressure measurements. A pressure measuring circuit generates a measured value of an applied absolute pressure provided to an input of the CDG. A tilt sensor generates at least one tilt sensor output value that is responsive to an orientation of the CDG with respect to the earth's surface. A processing system adjusts the measured absolute pressure value by a calibration factor to generate a calibrated absolute pressure value representing the applied absolute pressure, wherein the calibration factor is selected in response to the at least one tilt sensor output value.
