Step 2: Attach wind vane and counter-weight to the direction sensor head.

Loosen the two set screws on the top of the wind vane (upper unit).

Insert the vane and counter-weight into the holes. Be sure to press both parts all the way in and make sure the flat areas on each arm face the set-screws.

Tighten the set screws.

Note: For optimum performance and maximum bearing longevity you may wish to fine-tune the balance of both wind sensors. Place the U-tube flat on a table such that the sensors hang over the edge. Rotate the vane and the cup in 10 degree increments. After positioning the vane and cups verify that there is no movement after releasing your hold (this must be done in a wind-free environment). Balance adjustments are made by loosening the set screw to the lighter cup, counter-weight or fin and shifting it slightly away from the sensor head.

Step 3: Attach cross-bar to U-tube.

Spread end clamps and slide over the U-tube.

Insert cross-bar into the ends of both clamps.

Fasten cross-bar in a level position with screws, nuts and washers.

Step 4: Attach U-bolts to cross-bar and U-tube.

Remove the two nuts and reinforcing plate from both U-bolts (do not remove the toothed bracket). Insert one U-bolt through the two holes in the cross-bar and the other through the two holes in the bottom of the U-arm (be careful not to damage the wires inside the U-arm).

Replace the tube reinforcing plate on the U-bolt and replace the U-bolt nuts.

Step 5: Slip the U-bolts over the mast and tighten.

Make certain that the anemometer cups do not hit the mast.

Step 6: Attach guy wire clamp just below the U-tube assembly.

Step 7: Attach base mount to the roof or side wall.

Note that the base mount U-bolt will rotate to fit any angle.

Step 8: Install guy wire anchors (not included) or locate secure points for guy wire attachment.

Step 9: Erect mast and install guy wires (not included) and turn-buckles(not-included).

Step 10: Ground the mast to help protect the sensors and structure from lightning hits. Supplies needed: mast wire clamp, grounding wire, wire supports and grounding rod.

Step 11: Run the sensor wire inside to the console.

Lead in wire is permanently attached to the sensor unit. Attach to console according to wire color code.

If necessary the cable may be cut down in length or wire may be added with negligible effect on the calibration. If changing cable lengths more than a few hundred feet you may wish contact the factory to determine the severity of the effect on calibration.

Additional cable lengths are available from Texas Electronics if needed.

Step 12: Calibrate the Wind Vane.

Be sure console is operating properly first.

This is normally a two man job with one individual watching the direction indicated by the weather station and the other adjusting the sensor while watching a compass.

TR-525USW, SERIES 525 RAINFALL SENSORS, TR-525I specifications

Texas Instruments, a leader in innovative technology solutions, has garnered significant attention with its TR-525I and Series 525 Rainfall Sensors, particularly the TR-525USW variant. These sensors are designed to provide accurate and reliable rainfall measurement, making them an essential tool for various applications including agriculture, hydrology, and environmental monitoring.

The TR-525I features a robust design that allows for seamless installation and integration into existing weather stations or standalone applications. Its state-of-the-art technology ensures real-time data collection with minimal maintenance, thereby enhancing user convenience. The sensor employs a tipping bucket mechanism, which distinguishes it from traditional rainfall measurement techniques. This innovative design consists of a calibrated bucket that tips once a predetermined amount of rainfall accumulates, typically 0.2 mm. Each tip is recorded electronically, allowing for precise rainfall measurement over time.

One of the standout features of the Series 525 Rainfall Sensors is their advanced data logging capabilities. The TR-525USW variant integrates sophisticated software that enables users to monitor rainfall data remotely. This connectivity is particularly useful for agricultural planners who must assess environmental conditions regularly. The sensors can be integrated with wireless communication technologies, ensuring that data is transmitted efficiently to central databases or cloud-based platforms for further analysis.

Moreover, the TR-525 series offers excellent durability, making it suitable for various weather conditions. With IPX4 water-resistant housing, these sensors can withstand rain, snow, and other harsh environmental elements without compromising performance. The rugged design is advantageous in rural and remote locations where harsh conditions are prevalent.

Accuracy and precision are crucial in meteorological instruments, and the TR-525 series excels. With a measurement range that accommodates both light and heavy rainfall, the sensor ensures that even the slightest precipitation is recorded. Furthermore, periodic calibration ensures that accuracy is maintained over time, making it a reliable choice for critical applications.

In summary, the Texas Instruments TR-525I and Series 525 Rainfall Sensors, particularly the TR-525USW variant, offer cutting-edge technology, reliable performance, and exceptional durability. Their advanced features make them invaluable for anyone in need of precise rainfall measurements, enhancing decision-making processes in agriculture, environmental monitoring, and beyond. As weather patterns continue to change, the importance of reliable rainfall data cannot be overstated, and Texas Instruments is well-positioned to meet this need.
