Abstract:
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; further comprising: at least one alarm generating component in said alarm circuit means; said at least one alarm component generating said at least one alarm signal; said at least one alarm component being at least one of an audible alarm unit, a visual alarm unit, a wired electronic message alarm unit, a wireless electronic message alarm unit, and a mechanical alarm unit; and said at least one alarm signal being at least one of an audible signal, a visual signal, an electronic signal, an electronic message signal, and a mechanical signal, whereby said one at least one alarm component is effective to notify a user of said alarm signal, said means for retaining and positioning said alarm body proximate said pressure gauge includes at least one of an elastomeric member system, a cover system, and an adhesive system; said elastomeric member system including an elongated elastic member; said elastic member elastically retaining and repositionably holding said alarm body relative to an outer circumference of said pressure gauge; said elastic member enabling said user to position and retain said alarm body along said outer circumference relative to said first desired position; and said elastic member urging said alarm body into a stabilizing close contact with said outer circumference during said use, whereby said means for sensing reliably senses said needle relative to said first desired position during said use.
