Product Specifications

High Accuracy and Stability

Accurate within ± 1.5 kPa across a pressure range of 15

to 115 kPa (4.43 to 34.96 in Hg). Long-term non-stability

has been measured continuously indoors and in natural

conditions (with sensors mounted inside a datalogger

enclosure) for multiple sensors and is less than 0.5 %

per year. Temperature effects on signal are less than 1 %

across a wide temperature range (-20 to 50 C).

Low Power, Large Signal

Pressure sensor power requirement is approximately 35

mW (7 mA current draw at 5 V DC). Voltage output ranges

from 0 to 5 V DC for a pressure range of 15 to 115 kPa.

Small Size

Sensor is small and lightweight enabling easy deployment

within a datalogger enclosure, protecting the sensor from

the elements.
