Leybold LDS1000 Modular Leak Detection System for Integration in Leak Testing Systems 1x Mass spectrometer TTR211515730 1x Turbovac TMP35 LS and 1x re-conditioned spare turbo TMP35 LS 1x Leybold calibrated leak 145 49 TL7 - LDS1000 1x PLC Control RS232 - 19" Electronics rack module 1x Connection cable electronics module 1x Instruction manual 1x S/S Fixed volume 1x Right angle isolation valve 1x Various vacuum fittings Modular concept for flexible system design. The LDS1000 is a helium leak detector for universal integration in industrial leak testing systems (vacuum or sniffer mode). The modular design concept allows the cost effective and flexible integration into systems for various applications. Specifications: Smallest detectable helium leak rate: FINE mode mbar x l x s-1 < 5 x 10-11 GROSS mode mbar x l x s-1 <3.5 x 10-10 Sniffer mode mbar x l x s-1 <1 x 10-7 Units of measurement (selectable): mbar x l x s-1, Pa x m3 x s-1, atm x cc x sec-1, g/a, ppm Max inlet pressure: mbar 3 (0.3 in FINE mode) Response time: <1 s Ion source: 2 yttrium/irridum long life cathodes Vacuum connections: DN16KF Relays: 4 Control inputs: Programmable control compatible (max. 35V) Charge recorder output lin/log: 0-10V Interface: RS232 Features: Fast response time for short testing cycles. Measurement of the true leak rate of the test sample while simultaneously pumping down the test chamber (partial flow operation). Easy to operate. Switching over from vacuum leak detection to sniffer leak detection upon a single key press allows for immediate pin-pointing of the leak during the same test step. Control and acquisition of data via programmable control compatible signals or RS232 interface. Control and data acquisition software LDS-WARE (optional). Chart recorder output 0-10V lin/log for logging the leak rate and the fore vacuum pressure. Calibration through internal calibrated leak. Additionally calibrations with external test leaks (master testers) or dynamic calibrations are possible. Electronics module prepared for mounting in a 19" rack, offering protection against dust, high temperatures or electromagnetic interference. The operating unit may also be detached from the instrument and been used in any position.
