Abstract

A gas sensor 1 has a catheter 3 to which a gas sensor body 4 and a signal guide member 5 for guiding a detection signal of the gas sensor body 4 are attached. The other end of the signal guide member 5 is connected to a connector 6. The gas sensor 1 is airtightly received in the reception body in the state where a connection terminal of the connector 6 is exposed to the outside. The reception body 2 is filled with a mixed gas containing a gas to be measured by a predetermined concentration. At the time of calibration, the connection terminal of the connector 6 is connected to a measurement amplifier while the reception body 2 is not opened and calibration is performed, and at the time of measurement, the reception body 2 is opened and the gas sensor 1 is taken out to perform ordinary measurement.

Claims

1. A gas sensor package comprising:

a reception body for accommodating the gas sensor, said reception body being filled with a gas having a predetermined concentration in a seal condition; and

a connector for transferring a signal from the sensor to guide it to an external portion of the reception body, the connector having a connection terminal exposed to the external portion of said reception body.

2. A gas sensor package as claimed in claim 1, wherein said reception body is made of a flexible material.

3. A gas sensor package as claimed in claim 1, further comprising:

calibration announcement means for recognizing the calibration mode, said calibration means accommodated into the connector.

4. A gas sensor package for receiving a gas sensor comprising:

a gas sensor body;

a signal guide member connected at its one end to said gas sensor body to lead a detection signal of said gas sensor body;

a connector connected to the other end of said signal guide member;

a reception body for receiving at least said gas sensor body and for airtightly receiving said gas sensor in a state where at least a connection terminal of said connector is exposed to the outside, and

an atmosphere filled in said reception body and containing a gas to be measured at a predetermined concentration.

5. A gas sensor package according to claim 4, wherein said connector of said gas sensor is constituted by a first connector having at its opposite ends connection terminals and a second connector detachably connected to one of said connection terminals of said first connector, said first connector being fixed to said reception body in a state where the other connection terminal is exposed to the outside of said reception body.

6. A gas sensor package according to claim 4, wherein said gas sensor has a catheter, said gas sensor body being attached to said catheter, the whole of said catheter being received in said reception body.

7. A gas sensor package according to claim 4 further comprising:

water and a water-holding material are received in said reception body.

8. A gas sensor package according to claim 4, wherein said reception body is provided with a connector holding member for holding said connector and having a hole portion which makes the inside and outside of said reception body communicate each other, said connector being held in said connector holding member through screw-engagement between respective screw portions formed in a circumferential surface of said connector and a circumferential wall surface of said hole portion.

9. A gas sensor package as claimed in claim 4, further comprising:

calibration condition announcement means for recognizing the calibration mode, said calibration means accommodated into the first connector.
