Cs105/cs105md barometric pressure sensor 1. General the cs105 analog barometer uses vaisala’s barocap ® silicon capacitive pressure sensor. The barocap sensor has been designed for accurate and stable measurement of barometric pressure. The cs105 outputs a linear 0 to 2.5 vdc signal that corresponds...
Page 6: 3. Installation and Wiring
Cs105/cs105md barometric pressure sensor supply voltage: 10 to 30 vdc supply voltage control: when enabled with an internal jumper, the cs105 is on continually. When disabled, the cs105 can be turned on/off with 5 vdc/0 vdc. Supply voltage sensitivity: less than 0.1 mb current consumption: µa (quies...
