Campbell Scientific 255-100 Novalynx Gage Specification

The Campbell Scientific 255-100 Novalynx Gage is a precision instrument designed for accurate measurement of liquid precipitation. This tipping bucket rain gauge is constructed with high-quality materials to ensure durability and long-term reliability in various environmental conditions. It features a robust aluminum housing that resists corrosion and physical wear, making it suitable for both standalone installations and integration into weather monitoring systems.

The gauge operates with a tipping mechanism that provides high-resolution data collection, with each tip correlating to a precise amount of rainfall, typically 0.01 inches or 0.2 mm per tip, depending on configuration. This mechanism ensures accurate and consistent measurements over time. The 255-100 model includes a built-in siphon to regulate the flow of rainwater into the tipping bucket, minimizing the effects of intense rainfall rates and enhancing measurement accuracy.

The gauge is equipped with a reed switch that generates a contact closure signal for each tip, allowing for seamless data logging and integration with Campbell Scientific data loggers or other data acquisition systems. The electrical output is designed to be compatible with a wide range of digital pulse counting devices.

Installation is straightforward, with provisions for mounting on a standard pipe or a custom platform, and it includes a leveling mechanism to ensure proper orientation. The 255-100 Novalynx Gage is designed to meet or exceed the accuracy standards required for meteorological and hydrological applications, making it an essential tool for researchers, meteorologists, and environmental monitoring professionals. Its reliability and precision make it a preferred choice for accurate rainfall measurement in diverse climatic conditions.

Campbell Scientific 255-100 Novalynx Gage F.A.Q.

How do I properly install the Campbell Scientific 255-100 Novalynx Gage?

To install the gage, mount it on a stable, level platform using the provided hardware. Ensure that the gage is placed away from obstructions and at a height that allows for accurate precipitation measurement. Connect the gage to your data logger using the appropriate cables and verify that it is securely fastened.

What is the recommended maintenance schedule for the Novalynx Gage?

Regular maintenance should include monthly inspections to clear any debris, bi-annual calibration checks, and an annual comprehensive inspection to ensure all components are functioning correctly. Adjust the schedule based on environmental conditions.

How can I troubleshoot inaccurate readings from the Novalynx Gage?

First, check for physical obstructions or debris in the funnel. Verify that the gage is level and recalibrate if necessary. Inspect the wiring connections for any damage or loose connections. If problems persist, refer to the user manual for detailed troubleshooting steps.

What are the common causes of data logging errors in the Novalynx Gage?

Data logging errors can be caused by power supply issues, faulty cables, or incorrect data logger configuration. Ensure that all power connections are secure, cables are intact, and the data logger is properly configured for the gage model being used.

Can the Novalynx Gage operate in extreme weather conditions?

Yes, the gage is designed to operate in a wide range of weather conditions. However, during extreme events such as heavy snow or hail, additional measures like heating elements may be necessary to ensure accurate readings.

How do I calibrate the Campbell Scientific 255-100 Novalynx Gage?

Calibration involves using a known quantity of water to verify that the gage measures accurately. Follow the calibration procedure outlined in the manual, which includes adjusting the calibration screws and verifying output with test measurements.

What should I do if the Novalynx Gage is not collecting any data?

Ensure that the gage is properly connected to the data logger and that the power supply is functioning. Check for any physical damage to the gage or its components. If issues persist, perform a diagnostic test using the data logger’s built-in functions.

How do I clean the Campbell Scientific 255-100 Novalynx Gage?

To clean the gage, remove any debris from the funnel and tipping bucket. Use a soft brush and mild detergent to clean the surfaces. Avoid using abrasive materials that could damage the sensors. Rinse thoroughly and ensure all parts are dry before reassembling.

What types of data can I collect with the Novalynx Gage?

The Novalynx Gage is primarily used to measure precipitation. It can collect data on total rainfall, rainfall intensity, and duration of precipitation events, which can be used for hydrological studies and weather forecasting.

How can I ensure the longevity of my Novalynx Gage?

Regular maintenance, proper installation, and timely troubleshooting are key to ensuring longevity. Protect the gage from physical damage and harsh environmental conditions, and always use manufacturer-recommended parts and accessories.
