摘要： A helium supply unit (1) supplies helium from a high pressure storage (21) to fill a test chamber (6) which encloses a sample holder (5) to be examined for leaks by measuring device (2) including a mass spectrometer (3) and a control unit (4). The test gas is recovered after the testing by a pressure difference between a low pressure storage (18) and the test chamber (6). The test chamber is evacuated prior to receipt of the test gas by a vacuum pump (27) and after testing by a vacuum pump (34) for more complete helium recovery. The recovered test gas is then transmitted back to the high pressure storage (21) through a compressor (19), which raises the pressure of the recovered gas to a predetermined pressure, from the low pressure storage (18). The control unit (4) also controls a pure test gas supply (37) and a release valve (44). The concentration of the recovered test gas is measured and, if the concentration is too low, the control unit (4) releases the recovered test gas through valve (44) and admits fresh test gas from the supply (37) into the helium supply unit (1) at a point between the low pressure storage (18) and the compressor (19). In this manner, expensive test gases, such as helium, are recovered and reused.

摘要： A test leak unit (1) includes a supply of test gas, preferably helium, and an element (14) for determining leakage rates. The aim of the invention is to create a simple, robust and easily refilled test leak unit, especially for detecting packaging leaks. To this end, the test gas supply is stored under substantially atmospheric pressure in a resealable reservoir (2) including a closing part (3), such that when the reservoir (2) is closed, a test gas-impermeable seal is developed between the closing part (3) and the reservoir (2), and the leakage rate-determining element (14) forms part of the closing part (3).

摘要： A measuring head for a vacuum gauge. An essentially cylindrical housing encloses a measuring cell which is sealed in a vacuum tight manner against the surrounding atmosphere and is connectable with an evacuatable cavity. A measuring filament for producing an electrical signal corresponding to the pressure in the measuring cell is disposed in the measuring cell. The measuring filament is disposed approximately perpendicularly to the axial direction of the housing.

摘要： A conduction-responsive meter head has a device having electrical conduction responsive to a condition such as pressure to be metered. The device communicates with the condition to provide its electrical-conduction response to a bridge electrically including the device. A power supply has two terminals on the meter head for providing electrical power to the bridge. The measurement signal from the bridge is provided, however, to a third terminal by a lead from the bridge.

摘要： A method for operating a film leak detector (1) which includes two films (5, 6) each stretched in a frame (3, 4), which, with a test sample (79) emplaced, delimit a test chamber (80). The detector is equipped with two vacuum pumps (13, 30), in which first the test chamber (80) is evacuated and, after the evacuation operation, a leak detection operation takes place. In order to avoid test gas pollution and impurities during the first phase of the evacuation of the test chamber (80), only one (13) of the two vacuum pumps is operated and during the leak detection operation only the second vacuum pump (30) is operated.
