THE MARS SCIENCE LABORATORY (MSL) ENTRY, DESCENT AND LANDING INSTRUMENTATION (MEDLI): HARDWARE PERFORMANCE AND DATA RECONSTRUCTION

(excerpt from Page 8)

The MEADS pressure transducers are manufactured by Stellar Technologies, Inc. and are derivatives of off-the-shelf transducers. They are strain gage-type transducers with a range from 0 to 5 psia, outfitted at the manufacturer with flight electrical connectors, pressure input fittings, and mounting brackets.

Miniature Pressure Transducer has Flush Diaphragm, Zero Dead Volume

The Series FT290 pressure transducers are designed for those applications requiring both a standard NPTmale process connection and a flush diaphragm with zero dead volume. These pressure sensors are designed with a unique diaphragm design which reduces stress levels caused by torquing a tapered thread into the mating fitting. Besides their small size (only 3.5 oz.), these pressure sensors are constructed of all welded stainless steel and can withstand demanding application environments.

Series AP50XX In-Line Amplifier from Stellar Technology

The Stellar Technology Series AP50XX in-line signal conditioner offers many options for those customers requiring high level output where application temperatures or physical size constraints do not allow having signal conditioning at the point of measurement. The AP50XX can be placed in-line anywhere between the transducer and the data acquisition system.

New DIN-Rail Amplifier for use with LVDTs

The new Series AP5104 is a convenient DIN-rail Amplifier for use with 4-, 5-, or 6-wire LVDT’s (linear variable differential transformer). The AP5104 provides regulated AC excitation with remote sensing capability for cable runs exceeding 20 feet. The AP5104 produces filtered analog outputs of ±0-5Vdc, ±0-10 Vdc, 4-20 mA, 4-12-20 mAwhich are field-selectable via the front panel.

New DIN-Rail Amplifier for use with DC Strain Gage Transducers

The new Model AP5101 is a DIN-rail mounted single channel Amplifier which provides variable excitation and signal conditioning for standard DC-excited strain gage transducers, including those for pressure, force, torque, and load. The AP5101 provides up to 10V output or 4-20 output with transducer signals from 10mV to 10V, and incorporates a DC-DC converter to insure that the output is electrically isolated from the supply. The unit accepts both uni-polar and bi-polar input signals and can produce corresponding uni-polar or bi-polar voltage outputs.
