Apogee Instruments SB-110 barometric pressure sensors combine excellent performance and affordability in a small, handy sensor. The sensor works well as a stand-alone product or it can be combined with sensors affected by barometric pressure, such as our line of oxygen sensors. The SB-110 consists of a silicon capacitive sensing element and signal processing circuitry mounted in a compact epoxy plastic/stainless steel housing and lead wires to connect to a measurement device. Sensors are weather resistant and are designed for continuous barometric pressure measurement when housed inside the same enclosure as the measurement device (e.g., datalogger or controller). Typical applications include pressure measurement in weather networks, often for weather forecasting and to correct the output of sensors sensitive to pressure changes. SB-110 pressure sensors output an analog voltage that is directly proportional to barometric pressure.
