PROBLEM TO BE SOLVED: To provide an abnormality detecting device which can find out an abnormality and diagnose a deteriorating factor to be a cause of the abnormality and a degree of the deterioration of the factor, etc., in a sealing device. SOLUTION: The abnormality detecting device 10 is arranged in relation to a flow channel passing through the sealing device 1 and provides a group of the detective devices 20 containing the temperature sensors 23, 27, the pressure gauges 21, 25 and a flow meter 29, a computer 30 which electrically connects with a devices 20 and can calculate the sealing flow quantity at a provisional conditions by using calculation program stored in the sealing device, and a display 40 showing the calculating output obtained from the computer 30. The device 10 can detect a symptom of the abnormality in comparison with an actual flow quantity and the calculating sealing flow quantity at the provisional conditions providing that no abnormality exists in the device.
