Calibration device, flexible bag with components of a calibration device and procedure for calibrating a sensor

摘要

The invention concerns a calibration device for calibrating a sensor (1), which is a sensor for determining a proportion of a gas to be detected (2) in a gas mixture, comprising:-One container (3), containing an electrolyte liquid (4) and two electrodes immersed in the electrolyte fluid (4) (51,52);A gas production chamber (6) which is located in the container (3) in such a way that the gas production chamber (6) surrounds at least partially a first electrode (51,52) of the two electrodes and is located in the gas production chamber (6) electrolyte fluid (4);A calibration chamber (7) with a guide (71), in which direction (71) the sensor to be calibrated (1) can be inserted at least partially,where the calibration chamber (7) is connected to the gas production chamber (6) by at least one lockable aperture (8),where by applying an electrical voltage (U) to the electrodes (51,52) the electrolyte fluid (4) at the first electrode (51) separates by electrolysis a gas mixture containing the gas to be detected (2),which gas mixture flows through the open lockable aperture (8) from the gas production chamber (6) to the calibration chamber (7).The invention also concerns a flexible bag (20) to provide components of the inventive calibration device and a process to calibrate a sensor (1) with an inventive calibration device.
