Qualifier

A system for monitoring a compressed air driven, pulse tool comprising:

• a means for measuring air pressure between the trigger of a pneumatic pulse tool and the motor and converting the air pressure into an electrical signal representative of the air pressure;
• a means for electrically computationally processing the electrical signal into another signal representative at least one parameter corresponding to a condition of the tool being monitored which is a function of air pressure;
• a programmed microprocessor configured to identify a portion of the signal representative of the air pressure corresponding to the parameter;
• wherein the programmed microprocessor is configured to identify and store the parameter of a first threshold air pressure to begin monitoring the parameter of a cycle;
• wherein the programmed microprocessor is configured to identify and store the parameter of a second air pressure to identify a portion of the signal representative of the air pressure of the tool driving a fastener to its target torque;
• wherein the programmed microprocessor is configured to identify and store the parameter of a third air pressure to count a completed cycle when the measured air pressure is in the same as the third identified and stored parameter;
• wherein the programmed microprocessor is configured to identify and store the parameter of a fourth air pressure to indicate a shut off region of the cycle when the measured air pressure is above the fourth identified and stored parameter;
• wherein the microprocessor is configured to indicate a pulsing region when the measured air pressure is between the third stored air pressure and the fourth stored air pressure;
• and
• wherein the programmed microprocessor is configured to confirm that the measured air pressure is in the pulsing region.
