Title: PRESSURE SENSOR DEVICE AND ELECTRICALLY POWERED PUMP
Abstract:
An embodiment of this pressure sensor device is a pressure sensor device for an electrically powered pump, the pressure sensor device comprising: a pressure sensor that measures the pressure of a fluid inside the electrically powered pump; a first terminal part and a second terminal part that project from the pressure sensor in a first direction extending toward one side in the horizontal direction; a third terminal part that projects from the pressure sensor in a second direction extending toward another side in the horizontal direction; a fourth terminal part that projects from the pressure sensor in the second direction and that is electrically connected to the second terminal part; a first capacitor that is arranged on one side, in the horizontal direction, of the pressure sensor and that is connected between the first terminal part and the second terminal part; and a second capacitor that is arranged on another side, in the horizontal direction, of the pressure sensor and that is connected between the third terminal part and the fourth terminal part.
