Leak test bench PPM SF6

automatichosefor workpieces

With this test stand, tightness tests can be carried out on rails: the pressure is generated by means of a pressure convertor. SF6 is contained in the high-pressure medium and the smallest leakage is determined in the vacuum chamber by means of a suitable laser sensor. The clamping device is located in the test chamber. It is adjustable and can therefore be used for almost every type of rail. Adaptation of the rails is carried out by means of high-pressure hoses and couplings by hand. The clamping and testing are carried out automatically. The control is controlled by a Siemens PLC. A touch panel is used as input and display unit. It can also be operated via a keyboard. All relevant measurement results are visualized. Performance data: Test pressure up to 2,700 bar Pressure holding time variable Leak rate measurement Various test points configurable Automatic clamping of the components Sequence for automatic operation: Place the test part Adapt Press Start Protective cover closes Clamping the rail Close the vacuum chambers Vacuum is generated Pressure build-up Pressure stabilization time and pressure holding time Concentration measurement Pressure reduction Medium is evacuated from the rail Hood opens i.
