1. A crimping system for crimping fittings on hoses, the system comprising:
a crimper machine having a processor configured to analyze collected information based on identified hose and fitting properties; perform a crimping operation based on the collected information and the identified hose and fitting properties; measure crimping characteristics for the crimping operation; and generate an alert based on the measured crimping characteristics and the collected information;
one or more sensors to measure an applied crimping force as at least part of the measured crimping characteristics for the crimping operation of a hose and a fitting;
the processor of the crimper machine further configured to detect an inaccurate crimp from measurements of the one or more sensors and the measured crimping characteristics due to spring back from the hose and the fitting;
a storage configured to maintain the collected information and update the collected information based on the measured crimping characteristics;
the measured crimping characteristics comprise force applied, applied force measurements and crimping duration;
the one or more sensors including a strain gauge to measure the applied crimping force; and
the crimper machine is configured to analyze the measured crimping characteristics to determine if a used crimping force is within a determined crimping force range.
