Abstract
An integrated sensor device includes first and second housings combined together and is attached to a wall of a conduit via a joint portion thereof. Specifically, the first housing has the joint portion and a pressure conducting hole and holds a temperature measuring unit therein for detecting a temperature of a medium flowing in the conduit. The second housing holds a pressure measuring unit therein for measuring a pressure of the medium which has been conducted through the pressure conducting hole. Accordingly, several measuring units (sensors) can be attached to one portion of the conduit, so that the attachment process is simplified.
Claims25
An integrated sensor device for attaching to an attachment device holding a medium therein to detect a state of the medium, said integrated sensor device comprising:
- a first housing having a first joining portion;
- a first measuring unit installed in said first housing for detecting a first state of said medium;
- a second housing, having a second joining portion, wherein said second joining portion detachably connects to a specific portion of said attachment device;
- and
- a second measuring unit installed in said second housing for detecting a second state of said medium;
- wherein said second housing holding said second measuring unit therein detachably connects to said first housing holding said first measuring unit therein through said first joining portion;
- wherein said first measuring unit communicates with an external area of said second housing to detect said first state when said second housing is connected to said first housing and said second joining portion is connected to said attachment device.
An integrated sensor device for detecting a state of a medium, comprising:
- a first sensor unit for detecting a first state of said medium, said first sensor unit including:
- a first housing defining a first passage therein and having a first joining portion having a first structure;
- and
- a first sensor accommodated in said first housing and exposed to said first passage for detecting said first state of said medium;
- and
- a second sensor unit connected to said first sensor unit through said first joining portion for detecting a second state of said medium, said second sensor unit including:
- a second housing defining therein a second passage for introducing said medium toward said first sensor by communicating with said first passage, and having a second joining portion, said second joining portion having a second structure identical with said first structure of said first joining portion;
- and
- a second sensor accommodated in said second housing for detecting said second state of said medium.
An integrated sensor device for detecting a pressure and temperature of a medium, comprising:
- a pressure sensor unit which detects a pressure of a medium, said pressure sensor unit including;
- a first housing defining a passage therein, said passage containing a pressure sensor, said first housing having a first joining portion, said passage opening to one surface of said first housing;
- a temperature sensor unit which detects a temperature of a medium, said temperature sensor unit having a second housing, said second housing including:
- an attachment device joining portion provided on an external surface of said second housing, said attachment device joining portion detachably connectable to an attachment device, said reachment device joining portion substantially fluidly sealing an outer surface of an inside portion from an outside surface of an outside portion when said attachment device joining portion is connected to said attachment device;
