| 摘要 |
The present invention relates to an automated sensor calibration system and method for calibrating a gas sensor in-situ in a controlled atmosphere workstation. The system comprises a control means for automatically controlling the calibration system; an enclosure means movable between a first position and a second position; and a drive mechanism, operable by the control means, for moving the enclosure means between the first position and the second position. In the first position, the enclosure means is arranged in a spaced relationship from the sensor such that a sensing head of the sensor is exposed to the controlled atmosphere of the workstation. In the second position, the enclosure means is arranged in engagement with at least one surface so as to define a calibration chamber and enclose the sensing head in the calibration chamber. |
