Abstract:
A system for monitoring a mechanical tool with a mechanical switch comprising:the mechanical tool including a means for stimulating the switch wherein the switch can provide electrical signals upon reaching a mechanical parameter; the mechanical tool also including a transmitter for sending the electrical signals to a receiver; a remote qualifier including a receiver for receiving the electrical signals from the transmitter of the mechanical tool; the remote qualifier also including a means for electrically computationally processing the electrical signals into other signals representing at least one parameter corresponding to a condition of the mechanical tool being monitored which is a function of the condition, wherein the means for electrically processing the signals includes a programmed microprocessor configured to identify a portion of the signals representative of the mechanical switch condition corresponding to the parameter and wherein the programmed microprocessor is configured to identify and store the parameter of a first period of time for the electrical signal to attain a predetermined level and also configured to identify and store a second period of time for the electrical signal to remain at that level; and a means for displaying the parameter.
