Abstract

PURPOSE:To obtain a device which is freely mounted and is strong against dirt and is easy to handle and has the response averaged, by connecting a pressure sensor unit and a pipe for pressure introduction through an air chamber which is hermetically sealed except the hole of this pipe. CONSTITUTION:A pressure sensor unit 3 consists of an amplifier 2 for amplifying a sensor signal and a print board 4 as one body and is sealed hermetically by a resin 5 in a case 1 with only a pipe part 31 exposed. A cover 7 having a pipe 10 for pressure introduction is sealed hermetically to the case 1 and is adhered to the case 1 by an adhesive 6. An air chamber 8 for the connection between the sensor unit 3 and the pipe 10 is formed with a left space of the case between the resin 5 and the cover 7. A filter 9 is provided, and this device is used for preventing the dirt of the sensor unit 3 without changing the structure in case that a pressure detecting medium to be introduced is dirty specially.
