Campbell Scientific CS700 Sensor Specification

The Campbell Scientific CS700 Sensor is a robust, high-performance device designed for accurately measuring precipitation. It employs a tipping bucket mechanism to quantify rainfall, providing precise data essential for hydrological studies and meteorological applications. The sensor's construction features a durable, corrosion-resistant housing, ensuring long-term reliability in diverse environmental conditions. It supports an orifice diameter of 20.3 cm, facilitating the efficient capture of rainfall. The CS700 is engineered to deliver a measurement range from 0 to 500 mm per hour with a resolution of 0.1 mm per tip, offering reliable accuracy for detailed rainfall analysis.

The sensor integrates seamlessly with Campbell Scientific's data loggers, enabling efficient data collection and management. It supports a simple two-wire connection for easy integration into existing monitoring systems. The CS700 operates over a wide temperature range, from -20°C to 50°C, making it suitable for varied climatic conditions. Its low power consumption design ensures extended operation in remote locations without frequent maintenance. The sensor is also equipped with a debris filter to prevent clogging and maintain measurement accuracy. With these specifications, the Campbell Scientific CS700 Sensor is an optimal choice for researchers and professionals seeking dependable and precise precipitation measurement solutions.

Campbell Scientific CS700 Sensor F.A.Q.

How do I properly install the Campbell Scientific CS700 sensor?

To install the CS700 sensor, first secure the sensor to a stable mounting platform using the supplied mounting bracket. Ensure that the sensor is level and unobstructed by surrounding objects. Connect the sensor's cable to a compatible datalogger, following the wiring diagram in the user manual.

What is the procedure for calibrating the CS700 sensor?

Calibration of the CS700 sensor typically involves comparing its readings with a known standard or reference. Ensure the sensor is clean, and follow the calibration instructions provided by Campbell Scientific, which may involve adjusting calibration coefficients in the datalogger software.

How can I troubleshoot if the CS700 sensor is not providing data?

First, check the power supply and connections to ensure they are secure. Verify that the datalogger is configured correctly to read the sensor. Consult the sensor's diagnostics in the datalogger software for any errors, and ensure that the sensor is not obstructed.

What maintenance is required for the CS700 sensor?

Regular maintenance includes cleaning the sensor to remove debris, checking and tightening any loose connections, and verifying calibration accuracy. It is also advisable to perform periodic inspections for physical damage and to ensure the sensor is level.

Can the CS700 sensor operate in extreme weather conditions?

Yes, the CS700 is designed to function in a variety of weather conditions. However, extreme conditions, such as heavy snowfall or ice, may require additional maintenance or protective measures to ensure consistent functioning.

How do I connect the CS700 sensor to a Campbell Scientific datalogger?

Connect the sensor's output wires to the appropriate terminals on the datalogger, as specified in the wiring diagram. Configure the datalogger's software to recognize the sensor and to record its data, using the settings provided in the sensor's manual.

What should I do if the CS700 sensor's readings are inaccurate?

Check for any obstructions or debris on the sensor. Verify that the sensor is properly calibrated and that the datalogger settings are correct. If problems persist, consult the troubleshooting section of the user manual or contact Campbell Scientific support.

Is it possible to integrate the CS700 sensor with third-party software?

Yes, the CS700 sensor's data can be integrated with third-party software by exporting the data from the datalogger in a compatible format. Ensure that the third-party software supports the data format used by your datalogger.

What are the common causes of signal interference with the CS700 sensor?

Common causes of signal interference include nearby electrical equipment, inadequate grounding, and long cable runs. To minimize interference, use shielded cables, ensure proper grounding, and keep cables as short as possible.

How can I update the firmware of the CS700 sensor?

Check the Campbell Scientific website for the latest firmware updates. Follow the instructions provided with the firmware package, which typically involves connecting the sensor to a computer via a datalogger and using specialized software to perform the update.
