ES Systems - Model ESCP-SAPT -Standard Accuracy Pressure Transducers (SAPT)

ESCP-SAPT pressure transmitters consist of a MEMS capacitive pressure sensor die, which is underpinned by ES’ innovative microfabrication process that has been proven suitable for the mechanical, radiation and temperature environment of space applications. The full custom, radiation-hardened signal conditioning IC was designed entirely by ES, utilizing a standard deep submicron CMOS process of a European foundry.

ESCP-SAPT is an all-welded Titanium (Ti6AI4V) sensor, optimized to achieve the lowest mass possible (<160 g) combined with compact size (110mm x 55mm x 40mm) while being compatible with both low-pressure ranges (7 bar, 22bar) and high-pressure ranges (150 bar, 310 bar).

ESCP-SAPT features an analog pressure output (0-5 V) along with temperature reading to accommodate offline calibration and temperature compensation and reach an accuracy of ±0.3 % FS. *Developments are made under an activity funded by the European Space Agency.
