The fan of this machine adopts variable frequency control. And the monitoring system uses embedded Monitor, uses the unique control algorithm and enables it to be more accurate, stable and reliable. Solenoid valve controls spray, operates conveniently. Improved pilot clamping bodies can save more time and effort. CWKS Digital program-control type : Digital tube displays the pressure of wind and the air flow; LCD displays the deformation and deflection. Only to press a button to accomplish a detection steps, it can operate in order at the standard steps then finish the whole test. Monitor automatically calculates the deflection and the value of P1, P2, P3, and the preserve for view, and will not lose the data when power off. The judgment of results completes artificially. CWWS Computer control type: On the base of the CWKS function, It communicates by Ethernet The software can automatically finish test by í¦one key typeí¦, evaluate testing results and print the reports. It can complete the by semi-automatically control when testing machine is offline, which is real double-control and double-display. ó(íóMain Technical Specifications 1íóWater tightness testú¦ Range of water flow supply:100í½1000L/h Accuracy levels:1.5; Range of tricking water:2í½3L/m2.min; Range of control pressure:ú½100Paí½ú½5000Pa; Accuracy:ú+í+2% ;Resolution:1Pa; 2íóAir tightness test: Span of flux:0í½520m3/h Precision levels:1.5; Range of controlling pressure:í+10Paí½í+150Pa ú+Accuracy:ú+í+1Pa; Resolution of pressure:0.1Pa; 3íóProperties of wind pressure test: Range of regulation:-5000Paí½ú½5000Pa;Accuracy of sensor:0.2úÑ; Range of controlling pressure:í+100Paí½í+5000Pa Precision:ú+í+2úÑ; Resolution of displacement:0.01mm;Resolution of pressure:1Pa; 4íóFluctuating period of compression:3sí½5s; Fluctuating time of each grape:5min; 5íóControl mode:Computer control full automation and programmed control semi automation; 6íóPower supply:380Ví+10úÑú¼50Hzíú
