Zusammenfassung:	The utility model relates to an on-line calibration device for a differential pressure transmitter. INCLUDING STANDARD CALIBRATION TABLE, a high-pressure side connecting pipe is arranged at the high-pressure measuring end of the standard calibration meter; the low-voltage measuring end of the standard calibration meter is provided with a low-voltage side connecting pipe. The high-pressure side connecting pipe and the low-pressure side connecting pipe are respectively connected with the quick union; the quick union on the high-pressure side of the standard calibration meter is used for being connected with the high-pressure side blow-off end of a differential pressure transmitter to be calibrated, the quick union on the low-pressure side of the standard calibration meter is used for being connected with the low-pressure side blow-off end of the differential pressure transmitter to be calibrated, and a hand-operated booster pump is arranged on the high-pressure side connecting pipe. According to the utility mod
