Barometric Pressure Smart Sensor - S-BPB-CM50

The Barometric Pressure Smart Sensor has a measurement range of 660 mb to 1070 mb (19.47 to 31.55 inHg), and can perform measurement averaging to obtain the highest accuracy. The operating temperature range for this sensor is -40° to 70°C (-40° to 158°F). This weatherproof smart sensor is mounted outside the logger enclosure.

Specification: This product meets CE specification EN61326-1 criterion C for ESD, criterion C for Radiated Immunity, criterion C for Fast Transient, criterion B for Conducted Immunity, criterion A for Power Frequency Magnetic Fields, and Class B for Radiated Emissions Group 1. To minimize measurement errors due to ambient RF, use the shortest possible probe cable length and keep the probe cable as far as possible from other cables.

* A single HOBO Weather Station can accommodate 15 data channels and up to 100 m (328 ft) of smart sensor cable (the digital communications portion of the sensor cables).
