About
Bradford’s Miniaturised Pressure Transducer is optimised for small spacecraft where mass and volume are critical. Covers 3–320 bar with the same ±0.3% FS BoL accuracy as the Standard model at 180 g. Compatible with all major propellants including Hydrazine, MON, MMH, LMP-103S, GHe, GN2 and others. Data interface 0–5V analogue, power single 28V or dual ±15V.
