Determining the gap between gas welding - cutting equipment and a workpiece
摘要
<p>Gauge comprises a counter pressure detector whose chamber has inlets for hydraulic medium. Devices create turbulence in the chamber and nozzle head has an outlet for the hydraulic pressure from the chamber which has a detector opening. This determines the counter pressure created by the impact of the hydraulic medium on a work piece and feeds it into a converter which converts it into control signals.</p>
