特徴とする圧縮空気の残量警報器。 The free end of the Bourdon tube 4 is displaced by the change in pressure accompanying the use of compressed air in the compressed air tank 1, and the needle 5 is moved along the scale plate 6 in accordance with the movement of the free end of the Bourdon tube 4. In a residual pressure gauge that measures the residual pressure in the compressed air tank 1 by rotating and displacing the needle; At the same time, a reed switch 7 is arranged in the alarm required low pressure display area on the scale plate 6, and is rotated to the alarm required low pressure display area when the compressed air pressure in the compressed air tank 1 reaches the alarm required low pressure. The reed switch 7 is closed by the magnet 8 at the tip of the needle, and the piezoelectric ceramic vibrator 9 placed at the bottom of the residual pressure gauge is operated by power supply from the internal battery power supply, and is assisted by the above vibration. A compressed air remaining amount alarm device characterized in that a vibration plate 11 is vibrated to issue an alarm to a diver.
