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
