MPS34C Independent Ps and Pt control RVSM compliant 5000 hour pump guarantee 4 hour battery back-up Multiple line switching • • • • • MPS34C High Precision Digital Air Data Test Set Exclusive 5000 hour pump life guarantee The MPS34C is a rugged flight line instrument designed for low maintenance. Designed by DMA, the low maintenance internal pressure and vacuum pumps run only on demand, extending the pump life and carrying a 5000 hours industry exclusive guarantee, based on test set running hours. Automated ca librat ion Calibration, performed by software, is fast and simple since no mechanical adjustments are required. Calibration factors are password protected for security. The resultant accuracy of the vibrating element sensors exceeds the RVSM industry requirements. Flexible Multiple line switch ing By means of independently addressable ports the MPS34C is configured to control up to 8 lines of isolation: 4 ports for static and 4 for pitot. This multiple line switching permits fast and safe isolation of the lines to isolate leaking channels. Control is possible from any of the local or remote user interfaces. Combinations of line switching are also possible for numerous fault finding routines. Low power consumpt ion for high reliability Careful consideration during the design ensures low power consumption giving minimal internal temperature rise which consequently results in high reliability: typically 110 VA power consumption from the a.c. line. Inte rnal bate ry for sa fet y and versat ility The MPS34C is equipped with internal rechargeable batteries which provide an emergency power supply able to give up to four hours of full operation. This battery power feature also ensures that operation away from available a.c. supplies causes no problems to the operator. For those occasions when the a.c. power fails during a test there is a complete and seamless transfer over to the battery power permitting testing to continue and safe shutdown with total control. Built in Safet y limits for UU T protect ion The MPS34C is designed for maximum safety during testing. Key DMA design features protect both the test set and the systems under test. Negative Qc, a pressure condition of Ps greater than Pt, is prevented in both manual and automatic operation. In the unlikely situation where both a.c. and internal battery operation is not possible the Unit Under Test (UUT) is safely isolated and can be manually vented preventing instrument and test set damage. Numerous preset factory or user programmed safe limits are provided to prevent damage to the UUT. These limits can be modified by the user either temporarily or permanently, with password protection if desired. Supp lying Air Data Test SETS TO THE world DMA traces its origins back to 1938, mainly as a test equipment manufacturer to support European aviation requirements. Today DMA supply precision Air Data Test Sets and other aviation ground support equipment to aircraft manufacturers, repair stations and operators throughout the world. Flight line teste r for dema nding ap licat ions The MPS34C is a two channel digital technology portable Air Data Test Set incorporating many standard features normally found on more expensive test instruments. The construction is both rugged and rainproof for demanding flight line use. The unit is housed in a single wheeled case with a stowable handle. Eas y intuitive inte rface Using logical key press routines the MPS34C is easy to use by both beginners and experts. Testing and trouble shooting can be performed via the built-in intuitively arranged color-coded keypad and large 4 x 20 character back-lit display. For a remote location such as the flightdeck, three control options are available: the Hand Held Remote Control, the Touch Screen Remote Control or a wireless Bluetooth connected PDA. All the important air data functions are simultaneously displayed on all interfaces, constant screen or menu changes are not required. Readings of both commanded and measured test values are displayed. Laboratory testing can also be performed by a PC connected via RS232 to the remote hand terminal connector. The comprehensive manuals include all the control instructions. ADWIN software is available as a ready-to-run PC based interface. Acc urac y ach ieved by the end of se lf test Two vibrating element absolute transducers are utilized for the static and pitot channels. Pressure and temperature characterisation is applied to the sensors ensuring very high accuracy is achieved at all operating www.aero.cn 航空翻译 www.aviation.cn 本文链接地址：航空资料41
