Pfeiffer Vacuum Page 120 Vacuum Technology Pfeiffer Vacuum offers the “SmartTest” leak detector with the following equipment: Counterflow leak detector with turbopump and sector field mass spectrometer Calibration leak with automatic calibration Sniffer probe Digital display with automatic measurement range selection Audible leakage indication via the pitch of a signal tone Various types of backing pumps The SmartTest HLT 550 permits any suitable backing pump to be connected, making it ideally suited for integration into leak detector systems. Figure 5.5: SmartTest HLT 560 leak detector The SmartTest HLT 560 (Figure 5.5) is a helium leak detector with an integrated rotary vane pump offering a pumping speed of 5 m3 / h. With this configuration, leak detection in the vacuum mode is also possible within a reasonable period of time for larger workpieces (Table 5.1). The HLT 560 can naturally also be used in the sniffer mode when attached to vessels that are charged with helium. The SmartTest leak detector is mounted on a trolley together with larger backing pumps. The following versions are available: With a 30 m 3 / h rotary vane pump With dry backing pumps of various sizes if an oil-free environment is required (Figure 5.6) With a bypass option enabling large vessels to be pre-evacuated by means of an additional backing pump. During this phase, an upstream valve isolates the leak detector from the workpiece, thus preventing contamination of the leak detector With remote control and sniffer probe as accessories The versions described here are shown in Table 5.1. www.pfeiffer-vacuum.net
