Model 092 Barometric Pressure Sensor

5. Overview

The 092 ships from Campbell Scientific pre-wired for analog output with the

following settings:

• Analog Output Voltage: 0 to 5 Vdc

• Range: 600 to 1100 mbar

Refer to Appendix A, Analog Output Configurations, for available analog

output options.

The 092 uses an on-board microcontroller and piezoresistive pressure sensor

module. This module contains an analog-to-digital converter, a temperature

sensor, and non-volatile memory for storage of factory-determined calibration

coefficients. The microcontroller polls the sensor module once per second.

Measurements are temperature corrected, the calibration coefficients applied,

and the processed pressure measurement stored for output.

The pressure sensor element is light sensitive. Do not operate

the 092 without the top cover of the polycarbonate case securely

in place.

NOTE

All wiring terminals on the 092 are protected from static-surge damage by

transzorbs and current-limiting resistors.

Although the 092 is configured at Campbell Scientific for analog output,

digital output options including RS-232 and SDI-12 are available. Refer to the

MetOne 092, 594, 6633A Barometric Pressure Sensor Manual for more

information.
