Proportional technology Applications

Pressure control (2)

Material testing Fluid coating Flight simulator The force acting against the test piece is continuously increased until the test piece is destroyed. The spray pattern, i.e. the coating width, is adjusted by controlling the air supply through fan adjusting nozzles. The movements of an aircraft are simulated by applying different pilot pressures to the cylinders.

Temperature control Leak test Brake pressure The room temperature is held at a constant level by opening or closing ventilating shutters. The proportional pressure regulator precisely adjusts the test pressure to the different test pieces for leak test purposes. A set-point signal is used to gradually brake and slow down a rotating mass in accordance with the controller s speed profile.

Clamping pressure control The clamping pressure of machine tools is adjusted in accordance with the materials being used (steel, synthetic material, etc.).
