Campbell Scientific CS445 Sensor Specification

The Campbell Scientific CS445 is a submersible pressure transducer designed for accurate and reliable measurement of water level and temperature in a variety of environmental and industrial applications. This robust sensor is constructed from welded 316L stainless steel, providing excellent durability and resistance to corrosion, making it ideal for use in harsh environments. It features a piezoresistive sensor that delivers precise pressure readings, with a measurement range covering from 0 to 15, 30, 50, or 100 psi, corresponding to approximately 0 to 10.3, 20.7, 34.5, or 68.9 meters of water column, respectively. The CS445 offers an impressive accuracy of ±0.1% full scale across a wide temperature range of -10°C to +80°C. Integrated temperature compensation ensures consistent performance in varying conditions.

The sensor's output is a 4-20 mA signal, which is compatible with Campbell Scientific dataloggers and other data acquisition systems, facilitating easy integration into existing monitoring setups. The CS445 is equipped with a vented cable that mitigates the effects of barometric pressure changes, ensuring stable and accurate pressure readings. It also includes a desiccant tube to prevent moisture ingress, further enhancing its reliability and lifespan.

Installation is simplified by its compact design and the availability of various cable lengths, allowing the CS445 to be deployed in diverse settings such as wells, tanks, and open water bodies. The sensor is suitable for applications including groundwater and surface water monitoring, aquifer testing, and hydrological studies. Its dependable performance and robust construction make the Campbell Scientific CS445 a preferred choice for professionals seeking precise water level and temperature measurements in demanding environments.

Campbell Scientific CS445 Sensor F.A.Q.

What is the recommended method for calibrating the Campbell Scientific CS445 sensor?

The CS445 sensor should be calibrated annually using a reference thermometer in a controlled environment to ensure accuracy. Follow the calibration procedures outlined in the sensor manual.

How can I troubleshoot a CS445 sensor that is not providing any readings?

First, ensure all connections are secure. Check the power supply and verify that the sensor is properly connected to the data logger. If the issue persists, consult the troubleshooting section of the sensor manual.

What maintenance practices are recommended for the CS445 sensor to ensure longevity?

Regularly inspect the sensor for physical damage and clean it with a soft, damp cloth. Periodically check the cable and connections for wear and replace if necessary.

Can the CS445 sensor be submerged in water for extended periods?

Yes, the CS445 sensor is designed for continuous submersion in water. Ensure that the cable connection remains above the waterline to prevent water ingress.

What is the operating temperature range of the CS445 sensor?

The CS445 sensor operates effectively within a temperature range of -20°C to 70°C. Avoid using the sensor outside of these temperatures to prevent damage.

How do I integrate the CS445 sensor with a Campbell Scientific data logger?

Connect the sensor to the data logger using the appropriate channels. Configure the data logger using LoggerNet software to recognize the CS445 and set up measurement intervals as needed.

What should I do if my CS445 sensor is giving inconsistent readings?

Check for environmental factors that might affect the sensor, such as debris or algae growth. Recalibrate the sensor if necessary and ensure that it is securely mounted.

Are there any specific storage conditions for the CS445 sensor when not in use?

Store the CS445 sensor in a dry, cool place, away from direct sunlight and extreme temperatures. Ensure the sensor is clean and dry before storage.

How can I verify the accuracy of the CS445 sensor's readings?

Compare the sensor readings with a reliable reference thermometer under controlled conditions. If discrepancies are found, recalibrate the sensor.

What communication protocols does the CS445 sensor support?

The CS445 sensor primarily uses SDI-12 protocol for communication with data loggers. Ensure your data logger supports this protocol for seamless integration.
