Barometric Pressure Sensor

The BP40 Series Barometric Pressure Sensors are designed to measure atmospheric pressure in the range 800 to 1100 hectoPascals. The sensors use an integrated circuit sensor element, which has been laser trimmed for accuracy.

Housing the sensing element in a nylon package gives excellent corrosion resistance and isolation from external stresses. High quality electronics provide a frequency output that is immune to noise and cable losses. A two point calibration against a high quality standard (which is regularly recalibrated) ensures accuracy over the normal operating range.
