Barometric Pressure Smart Sensor - S-BPB-CM50

magnifier icon

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 data logger enclosure.

  • Weatherproof housing enables mounting outside the station enclosure. This means the station can maintain its weatherproof seal without having to be vented to the atmosphere.
  • Measures barometric pressure over a wide range
  • Includes zip ties for mounting on mast; can also be mounted on flat surface with screws

The S-BPB-CM50 Sensor is for use in Outdoor environments

The S-BPB-CM50 Sensor supports the following measurements:
