Model 083E Relative Humidity and Temperature Sensor

1. Introduction The 083E is a microprocessor controlled relative humidity and temperature sensor. Measurement ranges are 0 to 100% relative humidity and 50 to 50 C. It is commonly used in association with wind farm power performance measurements on permanent met towers.

This manual provides information only for CRBasic dataloggers. It is also compatible with most of our retired Edlog dataloggers. For Edlog datalogger support, see an older manual at www.campbellsci.com/old-manuals.

2. Precautions READ AND UNDERSTAND the Safety section at the front of this

manual.

The 083E is a sensitive instrument. It is particularly susceptible to damage and miss-calibration. Repair and re-calibration should only be attempted by trained repair technicians. If repair or calibration is required, refer to the customer assistance statement at the head of this manual and contact Campbell Scientific.

Do not touch the sensor element.

3. Initial Inspection Upon receipt of the 083E, inspect the packaging and contents for damage.

File damage claims with the shipping company.

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 Short Cut is an easy way to program your datalogger to measure the 083E and assign datalogger wiring terminals. Short Cut is available as a download on www.campbellsci.com and the ResourceDVD. It is included in installations of LoggerNet, PC200W, PC400, or RTDAQ.

Use the following procedure to get started.

7. Installation If you are programming your datalogger with Short Cut, skip Section 7.3, Wiring (p. 7), and Section 7.4, Programming (p. 7). Short Cut does this work for you. See Section 4, QuickStart (p. 1), for a Short Cut tutorial.

If the sensor is to be mounted in a radiation shield, refer to Section 7.2, Mounting (p. 5). Sensors not installed in a radiation shield should be mounted in a representative location having good airflow and shaded from sunlight or other radiant heat source.

7.1 Siting Locate sensors over an open level area at least 9 m (EPA) in diameter. The surface should be covered by short grass, or where grass does not grow, the natural earth surface. Locate sensors away from objects at least a distance equal to four times the height of the objects, and at least 30 m (EPA) from large paved areas. Protect sensors from thermal radiation and ensure adequate ventilation.

Standard measurement heights:

1.5 m (AASC) 1.25 to 2.0 m (WMO) 2.0 m (EPA)

See Section 10, References (p. 10), for a list of sources that discuss temperature and relative humidity sensors and siting.

7.2 Mounting When used in the field, the 083E must be housed in a radiation shield such as the 41003-5 or RAD14 naturally aspirated shields.

The white color of these shields reflects solar radiation, and the louvered construction allows air to pass freely through, thereby keeping the probe at or near ambient temperature. The RAD14 uses a double-louvered design that offers improved sensor protection from insect intrusion and driving rain and snow. In addition, the RAD14 shield has lower self-heating in bright sunlight combined with higher temperatures (> 24 C (75 F)) and low wind speeds (< 2 m/s (4.5 mph)), giving a better measurement.

The 41003-5 and RAD14 Radiation Shields attach to a crossarm, mast, or user- supplied pipe with a 2.5 to 5.3 cm (1.0 to 2.1 in) outer diameter. See FIGURE 7-1 for examples of shield mounting.

Tools required for installing a 083E sensor in a radiation shield to a tripod or tower include:

1/2-inch open-end wrench small screwdriver provided with datalogger UV-resistant cable ties small pair of diagonal-cutting pliers adjustable wrench with a minimum 1-7/8 inch jaw size

Attach the sensor cable to the connector on the bottom of the 083E.

7.2.1 Installation in a 41003-5 10-Plate Shield 1. The 083E is shipped with a hex plug to work with the 41003-5 10-plate

shield. Loosely thread the hex plug into the base of the 10-plate shield.

2. Insert the 083E sensor through the center of the hex plug. See FIGURE 7-1.

3. Hold the hex plug and sensor, and finish threading the hex plug into the shield by hand. Tighten the hex plug around the probe until it firmly grips the body of the probe.

7.2.2 Installation in a RAD14 14-Plate Shield 1. Loosen the nut on the entry gland at the bottom of the shield.

2. Insert the sensor up into the gland.

3. Using an adjustable wrench, tighten the nut on the gland until the sensor is held firmly in place. Do not over tighten.

7.2.3 Mount the Shield 1. Attach the radiation shield to the tripod mast, crossarm, or tower leg using

the supplied U-bolt. See FIGURE 7-1 for examples of shield mounting.

2. Route the cable to the datalogger, and secure the cable to the mounting structure using cable ties.

7.4 Programming Short Cut is the best source for up-to-date datalogger programming code. Programming code is needed when:

Creating a program for a new datalogger installation Adding sensors to an existing datalogger program

If your data acquisition requirements are simple, you can probably create and maintain a datalogger program exclusively with Short Cut. If your data acquisition needs are more complex, the files that Short Cut creates are a great source for programming code to start a new program or add to an existing custom program.

Short Cut cannot edit programs after they are imported and edited in CRBasic Editor.

A Short Cut tutorial is available in Section 4, QuickStart (p. 1). If you wish to import Short Cut code into CRBasic Editor to create or add to a customized program, follow the procedure in Appendix A, Importing Short Cut Code Into CRBasic Editor (p. A-1). Programming basics for CRBasic dataloggers are in the following section. A complete program example for a select CRBasic datalogger can be found in Appendix B, Example Program (p. B-1).

7.4.1 Relative Humidity Program Instruction For CRBasic dataloggers, relative humidity is measured using the VoltSE() instruction. Syntax of the VoltSE() instruction is:

NOTE

Model 083E Relative Humidity and Temperature Sensor

8

VoltSE(Dest, Reps, Range, SEChan, MeasOff, SettlingTime, Integ/FNotch, Mult, Offset)

7.4.2 Temperature Program Instruction For most CRBasic dataloggers, temperature is measured using the BRHalf() instruction. Syntax of the BRHalf() instruction is:

BrHalf(Dest, Reps, Range, SEChan, ExChan, MeasPEx, ExmV, RevEx, SettlingTime, Integ, Mult, Offset)

The CR200(X)-series dataloggers use the ExDelSe() instruction, which has the following syntax:

ExDelSE(Dest, Reps, SEChan, ExChan, ExmV, Delay, Mult, Offset)

The BRHalf and EXDelSe instructions provide a resistance value (see Section 8.3, Converting Resistance Measurement to Temperature (p. 9)).

8. Operation 8.1 Sensor Verification

To verify correct wiring and test the basic sensor operation, blow on the sensor. The moisture in your breath should cause the relative humidity reading to rise.

To ensure proper operation, check the output data against a relative humidity and temperature measuring device such as a psychrometer. Local weather service data should be used only as a guideline since relative humidity and temperature can vary significantly over short distances and over brief periods of time.

8.2 Limitations of RH Measurements at Below Freezing Temperatures

The relative humidity measurement is referenced to saturated water vapor pressure above liquid water. When air temperature is below freezing, the maximum theoretical measurement range is limited as follows:

Air Temperature (Deg C)

Maximum RH (%)

0 100 5 96

10 92 15 88 20 84 25 80 30 76 35 72 40 68 45 64 50 60

Appendix A. Importing Short Cut Code Into CRBasic Editor

This tutorial shows:

How to import a Short Cut program into a program editor for additional refinement

How to import a wiring diagram from Short Cut into the comments of a custom program

Short Cut creates files, which can be imported into CRBasic Editor. Assuming defaults were used when Short Cut was installed, these files reside in the C:\campbellsci\SCWin folder:

.DEF (wiring and memory usage information) .CR2 (CR200(X)-series datalogger code) .CR300 (CR300-series datalogger code) .CR6 (CR6-series datalogger code) .CR8 (CR800-series datalogger code) .CR1 (CR1000 datalogger code) .CR3 (CR3000 datalogger code) .CR5 (CR5000 datalogger code) .CR9 (CR9000 datalogger code)

Use the following procedure to import Short Cut code and wiring diagram into CRBasic Editor.

1. Create the Short Cut program following the procedure in Section 4, QuickStart (p. 1). Finish the program and exit Short Cut. Make note of the file name used when saving the Short Cut program.

2. Open CRBasic Editor.

3. Click File | Open. Assuming the default paths were used when Short Cut was installed, navigate to C:\CampbellSci\SCWin folder. The file of interest has the .CR2, .CR300, .CR6, .CR8, .CR1, .CR3, .CR5, or .CR9 extension. Select the file and click Open.

4. Immediately save the file in a folder different from C:\Campbellsci\SCWin, or save the file with a different file name.

Once the file is edited with CRBasic Editor, Short Cut can no longer be used to edit the datalogger program. Change the name of the program file or move it, or Short Cut may overwrite it next time it is used.

5. The program can now be edited, saved, and sent to the datalogger.

6. Import wiring information to the program by opening the associated .DEF file. Copy and paste the section beginning with heading -Wiring for CRXXX into the CRBasic program, usually at the head of the file. After pasting, edit the information such that an apostrophe (') begins each line. This character instructs the datalogger compiler to ignore the line when compiling.
