Model 092 Barometric Pressure Sensor
1. Introduction
The Model 092 Barometric Pressure Sensor is designed to measure ambient
atmospheric pressure and is configured at Campbell Scientific for analog
output. It is recommended for wind farm power performance research.
2. Cautionary Statements
•Install the sensor such that it faces North in the Northern Hemisphere, or
South in the Southern Hemisphere. This orientation will shield the
polycarbonate sensor housing from most direct sunlight.
•The pressure sensor element is light sensitive. Only operate the 092 when
the polycarbonate case is closed.
•Pressure conditions in the range of 10 to 10,000 millibars will not harm the
sensor, but the measurement accuracy is not guaranteed beyond the range
of 600 to 1100 millibars.
3. Initial Inspection
•Upon receipt of the 092, inspect the packaging and contents for damage.
File damage claims with the shipping company, but contact Campbell
Scientific to arrange for repair or replacement.
•The model number and cable length are printed on a label at the
connection end of the cable. Check this information against the shipping
documents to ensure the expected product and cable length are received.
4. Quickstart
4.1 Installation
Please review Section 7, Installation for complete guidelines.
To install the 092:
1. The 092 enclosure is pre-supplied with desiccant and does not need to be
opened.
2. Attach the 092 to the tripod or tower leg using the supplied U-bolts.
Figure 4-1 shows the 092 installed on a vertical mast.

4.2 Programming with Short Cut
Short Cut Program Generator for Windows can be used to program the
CR1000 datalogger to measure the 092 as outlined in the following procedure.
Short Cut can also program other 092 compatible Campbell Scientific
dataloggers.
1. Open Short Cut and click on New Program.
2. Select a scan interval.

3. Select 092 Barometric Pressure Sensor and click the right arrow to add
it to the list of sensors to be measured.
4. Define the name of the public variable, or use the default BP_mmHg to
hold the barometric pressure measurement. Select the desired units of
measure, or use the default mmHg.

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 – 5 VDC
•Range: 600 – 1100 mbar
Refer to Appendix A, Analog Output Configurations for available analog
output options.
The 092 utilizes 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 with the top cover of the polycarbonate case off.
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.

7. Installation
7.1 Mounting
The 092 is factory mounted to a solar shield. The solar shield mounts by way
of two U-bolts to a vertical pipe with diameter up to 2” IPS. Install the sensor
such that it faces North in the Northern Hemisphere, or South in the Southern
Hemisphere. This orientation will shield the polycarbonate sensor housing
from most direct sunlight.

8. Maintenance
8.1 Cleaning
Periodic cleaning of the sintered filter at the base of the unit may be required in
dusty conditions. Remove the filter and clean with distilled water.
8.2 Calibration
Calibration is performed against a NIST traceable standard. Calibration
coefficients are stored in non-volatile memory at the factory. No user
calibration procedure is available. The sensor must be returned to Met One
Instruments when calibration is desired. Yearly calibrations are recommended.
