Campbell Scientific CS500-L Probe Specification

The Campbell Scientific CS500-L Probe is a highly reliable sensor designed for precise and accurate atmospheric measurements. It primarily measures air temperature and relative humidity, making it suitable for various meteorological and environmental monitoring applications. The probe features a capacitive thin-film polymer sensor for humidity measurements and a platinum resistance thermometer for temperature readings, ensuring high accuracy and stability. It operates within a temperature range of -40°C to 60°C and has a humidity range from 0 to 100% RH, with an accuracy of ±0.3°C for temperature and ±2% RH for humidity.

Constructed with durability in mind, the CS500-L is housed in a robust, weather-resistant casing, which allows it to perform reliably in harsh environmental conditions. The probe is equipped with a 12 VDC power supply requirement and offers a low power consumption design, making it ideal for remote installations where power efficiency is crucial. Its compatibility with Campbell Scientific's data loggers ensures seamless integration into existing data collection systems, facilitating comprehensive data analysis and reporting.

The CS500-L Probe comes with a standard cable length of 3 meters, although custom lengths are available to suit specific installation needs. It is designed for easy maintenance, with a user-replaceable sensor element that minimizes downtime and extends the probe's operational lifespan. The probe's precision, durability, and compatibility make it an excellent choice for applications such as weather stations, greenhouse monitoring, and climate research, where accurate atmospheric data is essential for informed decision-making and analysis.

Campbell Scientific CS500-L Probe F.A.Q.

How can I install the Campbell Scientific CS500-L Probe for optimal performance?

To install the CS500-L Probe, select a location that represents the general area conditions. Mount the probe vertically at a height that is typical for the area being monitored. Ensure that it is free from obstructions that could affect readings. Follow the mounting instructions in the user manual to secure the probe properly.

What are the common troubleshooting steps if the CS500-L Probe is not providing accurate data?

Check the probe's connection to the data logger to ensure it is secure. Verify the calibration settings and inspect the probe for any physical damage. Also, ensure that there is no debris on the sensor and that it is installed in an appropriate location.

How do I calibrate the CS500-L Probe?

The CS500-L Probe is factory-calibrated, but if recalibration is necessary, it should be done using a known reference with similar environmental conditions. Follow the calibration instructions provided in the user manual to ensure accuracy.

What maintenance is required for the CS500-L Probe?

Regular maintenance includes cleaning the sensor to remove any dust or debris, checking the mounting structure for stability, and verifying the cable connections. An annual inspection is recommended to ensure the probe's longevity and performance.

Can the CS500-L Probe be used in extreme weather conditions?

Yes, the CS500-L Probe is designed to operate in a wide range of environmental conditions. However, extreme weather conditions may require additional protection or more frequent maintenance checks to ensure accurate readings.

How can I integrate the CS500-L Probe with a data logging system?

The CS500-L Probe can be integrated with Campbell Scientific data loggers via the provided cable. Connect the probe to the appropriate channel on the data logger and configure the logger to recognize the probe, using the setup instructions provided in the data logger's manual.

What should I do if the CS500-L Probe's readings are inconsistent?

Check the sensor for obstructions or dirt that could affect readings. Confirm the probe is properly installed and that there are no loose connections. Additionally, ensure the data logger is configured correctly and that the calibration settings are accurate.

How do I properly store the CS500-L Probe when not in use?

Store the CS500-L Probe in a dry, temperature-controlled environment. Clean the sensor before storage and avoid coiling the cable tightly to prevent damage. Use the original packaging for added protection if available.

What are the power requirements for the CS500-L Probe?

The CS500-L Probe operates with minimal power requirements and is typically powered through the data logger connection. Ensure the data logger is properly powered to maintain probe operation.

Is the CS500-L Probe compatible with other manufacturer's data loggers?

While the CS500-L Probe is primarily designed for use with Campbell Scientific data loggers, it may be compatible with other systems that support the same signal output. Verify compatibility with the specific data logger manufacturer before integration.
