Manual

General Description

The SBP270 Barometric Pressure Sensor is a high accuracy barometer designed for use with the CR7, 21X, and CR10 dataloggers. The picture above shows the SBP270, which includes the Setra Model 270 variable capacitance barometer, interface circuitry, 5 foot cable, and a rain-tight enclosure. Mounting brackets allow the SBP270 to be mounted either to a flat surface, or 1 - 1.5" NPT pipe.

NOTE: The black outer jacket of the cable is Santoprene® rubber. This compound was chosen for its resistance to temperature extremes, moisture, and UV degradation. However, this jacket will support combustion in air. It is rated as slow burning when tested according to U.L. 94 H.B. and will pass FMVSS302. Local fire codes may preclude its use inside buildings.
