Campbell Scientific CS450 Transducer Specification

The Campbell Scientific CS450 is a precision pressure transducer designed for accurate measurement of water level and temperature in a wide range of environmental monitoring applications. It features a robust stainless steel construction, making it suitable for harsh environments. The CS450 operates on a piezoresistive sensor technology that ensures high accuracy and reliability in data collection.

This transducer offers a pressure measurement range from 0 to 7, 35, or 70 meters of water column, depending on the model. It provides an accuracy of ±0.1% full scale at 20°C, with a temperature compensation range from -10°C to 40°C, ensuring stable performance across varying conditions. The device includes an integrated temperature sensor with an accuracy of ±0.2°C over a range of -10°C to 40°C, allowing for simultaneous temperature and pressure data acquisition.

The CS450 is designed with a digital RS-232 or SDI-12 output interface, enabling seamless integration with Campbell Scientific dataloggers and other compatible systems. It operates on a low power consumption model, requiring a supply voltage of 6 to 18 VDC, which makes it ideal for remote and solar-powered installations. The transducer's rugged design includes a welded housing and a vented cable that minimizes the risk of condensation and ensures long-term durability.

Additionally, the CS450's compact size and lightweight design facilitate easy deployment in various field conditions, from groundwater wells to surface water monitoring stations. The device's user-friendly configuration and calibration software enhance its functionality, providing users with a high degree of flexibility and control over their data collection processes. Overall, the Campbell Scientific CS450 is a versatile and reliable tool for precise environmental monitoring.

Campbell Scientific CS450 Transducer F.A.Q.

How do I properly install the Campbell Scientific CS450 transducer?

To install the CS450 transducer, ensure that it is mounted vertically in the liquid, using the proper mounting hardware. Make sure the cable is secured to prevent movement and potential damage. Follow the manufacturer's guidelines for depth and orientation.

What is the recommended maintenance routine for the CS450 transducer?

Regularly inspect the transducer for physical damage and clean the sensor face with a non-abrasive cloth. Check the cable for wear and ensure all connections are secure. Calibrate the transducer periodically to ensure accurate readings.

How can I troubleshoot inaccurate readings from the CS450 transducer?

First, verify that the transducer is properly calibrated. Check for debris or buildup on the sensor face. Inspect the cable and connections for damage. Ensure that the power supply and data logger settings are correct.

What should I do if the CS450 transducer stops communicating with the data logger?

Check all cable connections for security and damage. Ensure that the data logger settings match the transducer’s communication protocol. Test the cable continuity and replace it if necessary. Power cycle the system if all else fails.

Can the CS450 transducer be used in corrosive environments?

The CS450 transducer is designed with corrosion-resistant materials, but for highly corrosive environments, additional protective measures or a different model may be necessary. Consult Campbell Scientific for specific recommendations.

How do I calibrate the CS450 transducer?

Calibration involves immersing the transducer in a known depth or pressure and adjusting the data logger settings to match this reference. Follow the detailed calibration instructions in the user manual to ensure accuracy.

What is the impact of temperature on the CS450 transducer readings?

The CS450 transducer has built-in temperature compensation, but extreme temperatures can still affect readings. It is important to verify measurements in environments with significant temperature variations.

How do I clean the CS450 transducer without causing damage?

Use a soft, non-abrasive cloth with mild soapy water to clean the sensor face. Avoid using harsh chemicals or abrasive materials, as these can damage the sensor. Rinse with clean water after cleaning.

Is it possible to extend the cable length of the CS450 transducer?

Yes, the cable length can be extended, but it is important to use appropriate connectors and high-quality cables to prevent signal loss. Consult the manual for maximum recommended lengths and specifications.

What factors should be considered when selecting a mounting location for the CS450 transducer?

Choose a location that allows for stable and vertical mounting, away from turbulence and obstructions. Ensure easy access for maintenance and consider environmental factors like temperature and potential contaminants.
