GAS SENSOR DEVICE

摘要

To provide a gas sensor device capable of obtaining a satisfactory correction effect under a variety of different internal combustion engine operating conditions, a gas sensor device (1) according to the present invention is provided with a concentration sensor (4) for measuring the concentration of a gas and a pressure sensor (5) for measuring the pressure of the gas, and the gas sensor device (1) is provided with a measurement chamber (7) that is removed from a gas flow and has the concentration sensor (4) and the gas sensor (5) disposed therein and with a processing circuit unit (14) for adjusting the signal of the concentration sensor (4) using the signal of the pressure sensor (5). It is preferable for the processing circuit unit (14) to be provided with a response speed adjustment unit for causing the response speed of the detection signal of the pressure sensor to approach the response speed of the detection signal of the concentration sensor.
