力センサの検査装置。 In a pressure sensor testing device that tests static characteristics such as sensitivity and linearity of a pressure sensor based on the output generated in response to the pressure received by the pressure sensor by pressurizing or depressurizing the pressure sensor, Alternatively, a master sensor that generates a reference output in accordance with the reduced pressure, a sensor mounting means to which the pressure sensor is attached so that the same pressure as that of the master sensor is applied, and a pressure sensor attached to the sensor mounting means; A pressure generating means that pressurizes or depressurizes the master sensor by continuously changing pressure, and outputs of both the sensors during the pressurization or depressurization process by the pressure generating means are inputted at predetermined intervals, and the outputs of the two sensors are inputted at predetermined intervals and compared to the reference output of the master sensor. A pressure sensor inspection device comprising: a calculation means for calculating an output result of the pressure sensor based on a predetermined calculation formula.
