Gas supply pressure alarm device
First Claim
1. A pressure alarm device, for a pressure gauge having an indicator needle operable about a pivot, said pressure alarm device comprising:
- an alarm body;
at least a first means for sensing at least a first desired position of said needle relative to said pivot during a use of said pressure gauge and for creating a corresponding position signal;
said means for sensing and creating operably joined to said alarm body;
means for retaining said alarm body proximate said pressure gauge and for positioning said means for sensing relative to said first desired position;
alarm circuit means for receiving said position signal and for generating at least one alarm signal;
said means for receiving and generating operably joined to said alarm body; and
means for supplying power to said alarm circuit means, whereby during said use when said means for sensing and creating determines said needle is at said at least first desired position and creates said corresponding position signal, said alarm circuit means receives said position signal and generates said at least one alarm signal.

Abstract
The present invention provides a pressure alarm for use in conjunction with conventional pressure gauge unit systems, as a replacement pressure gauge and alarm, or as a pressure alarm system. The invention provides adaptable alarm feedback signals for an operator, preventing the unexpected loss of pressure when using a gas cylinder, pressure boiler, or other device. The invention provides an alarm that may be a visual, audible, electronic, or mechanical low-pressure alarm and may include a means of ordering replacement supplies or sending a warning message. A system controller and memory module prevents false alarms and eases the burden of the operator while allowing external input and control.
