The WS-MM-DP-925 barometer combines compensated and calibrated silicon pressure sensors with precision signal conditioning circuitry. The on board voltage-reference and reverse voltage protection offers independence from the voltage supply. Only unregulated DC-supply in the range from 7.5 to 24 VDC is required. The WS-MM-DP-925 is for use with non-corrosive, non ionic pressure media like air. The range of 800-1100mb absolute makes this cost effective semiconductor pressure sensor usable for barometric measurements, altitude corrections and other applications where only a reduced range is necessary. The semiconductor pressure sensor (XCC-BARO) is special calibrated for use in the atmospheric pressure range.
