Campbell Scientific TE525 Sensor Specification

The Campbell Scientific TE525 is a tipping bucket rain gauge designed for high-precision rainfall measurement in various environmental conditions. Constructed with durable UV-resistant plastic, the TE525 is engineered to withstand harsh weather, ensuring long-term reliability and minimal maintenance. The sensor features a dual-spoon tipping bucket mechanism that measures rainfall with an accuracy of 1% at up to 50 mm/h. Each tip of the bucket corresponds to 0.1 mm or 0.01 inches of precipitation, depending on the model variant, allowing for fine-resolution data collection.

The TE525 is equipped with a magnetic reed switch that generates a contact closure signal each time the bucket tips, facilitating easy integration with data loggers and telemetry systems. The rain gauge operates in a wide temperature range, from -20°C to 50°C, making it suitable for diverse climates. Its compact design, with a diameter of 16.3 cm and a height of 24.1 cm, allows for convenient installation on a variety of mounting platforms.

Calibration of the TE525 is straightforward, with minimal drift over time, ensuring accurate measurements throughout its operational lifespan. The sensor is compatible with Campbell Scientific's CRBasic data loggers, enabling seamless data acquisition and real-time monitoring. The TE525's robust design and precise measurement capabilities make it an ideal choice for meteorological, hydrological, and environmental research applications where accurate rainfall data is critical.

Campbell Scientific TE525 Sensor F.A.Q.

How do I properly install the Campbell Scientific TE525 sensor?

To install the TE525 sensor, mount it on a stable platform using the U-bolt and bracket provided. Ensure it is level using a bubble level tool, and position it away from obstructions to prevent rain shadow effects.

What is the maintenance schedule for the TE525 sensor?

Check the TE525 sensor every 3 to 6 months. Clean the funnel and tipping mechanism to remove debris and check for damage or corrosion. Calibrate annually to ensure accuracy.

How can I troubleshoot inaccurate readings from my TE525 sensor?

Start by checking for debris obstructing the funnel. Ensure the sensor is level and connected properly. Inspect the tipping bucket for wear or damage, and recalibrate if necessary.

What should I do if my TE525 sensor stops collecting data?

Check the power supply and data logger connections. Inspect cables for damage and ensure all connections are secure. If the problem persists, test the sensor with a multimeter or consult Campbell Scientific support.

How do I calibrate the TE525 sensor?

To calibrate, use a known volume of water and pour it slowly into the funnel. Compare the number of tips to the expected value. Adjust the calibration constant in the data logger if necessary.

Can the TE525 sensor operate in freezing conditions?

The TE525 is not heated and may not operate accurately in freezing conditions. Consider using it with a heater or placing it in a location with milder temperatures.

How do I clean the TE525 sensor?

Remove the funnel and clean it with mild soap and water. Use a soft brush to clean the tipping mechanism. Ensure all parts are dry before reassembling.

What data logger models are compatible with the TE525 sensor?

The TE525 sensor is compatible with most Campbell Scientific data loggers, including models like CR1000, CR3000, and CR6. Check the specific data logger's manual for compatibility.

How do I connect the TE525 sensor to a data logger?

Connect the sensor's two wires to the pulse channel on the data logger. Configure the data logger to recognize the sensor by setting the appropriate measurement parameters.

What is the typical lifespan of the TE525 sensor?

With proper maintenance, the TE525 sensor can last many years, often exceeding 10 years. Regular inspections and cleanings will help extend its operational life.
