Check device for air activated pressure valve |
摘要 |
A modified air activated pressure valve is described, together with a method for its manufacture, that has a pressure sensitive switch located in the inlet chamber and in the outlet chamber. These pressure sensitive switches are preset by the user to output a finite voltage (typically about 5 volts) only when they are exposed to a pressure that exceeeds some value. The outputs of both switches may then be displayed, as needed. Additionally, a display circuit is provided that gives an output signal only when both the inlet and the outlet chambers are at or above their intended pressures.
