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.

Individual wire leads connect to the CR1000 datalogger as shown in step 5 of
the procedure in Section 4.2, Programming with Short Cut. A generalized
wiring diagram is provided in Section 7.2, Wiring.

2

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.

Model 092 Barometric Pressure Sensor

2. Select a scan interval.

3

Model 092 Barometric Pressure Sensor

3. Select 092 Barometric Pressure Sensor and click the right arrow in the

middle of the page 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.

5. Sensor connections to the CR1000 datalogger are shown in the Wiring

tab.

6. Select the desired output data for final storage and click Finish.

7. Click Wiring Diagram for a description of sensor wiring for this example.

Send the program from the PC to the CR1000 datalogger when prompted
if a telecommunications link is active.

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.

NOTE

The pressure sensor element is light sensitive. Do not operate
the 092 without the top cover of the polycarbonate case securely
in place.

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.
