NOZZLE STATUS MONITORING APPARATUS

摘要

PURPOSE: A nozzle condition monitoring device is provided to precisely monitor a condition of a nozzle end by using a piezoelectric effect which measures a voltage generated by a piezoelectric sensor transformed when a target material is sprayed. CONSTITUTION: A nozzle condition monitoring device includes a sensing unit, a measuring unit (20), and a control unit (30). The sensing unit senses a voltage generated according to a flow rate and pressure for spraying a target material passing through a nozzle end. The measuring unit measures the voltage generated by the sensing unit. The control unit compares and analyzes the voltage measured by the measuring unit and a preset voltage range, thereby monitoring a condition of the nozzle end.
