Campbell Scientific HMP60 Sensor F.A.Q.

How do I connect the HMP60 sensor to a data logger?

To connect the HMP60 sensor to a data logger, use the appropriate cable that comes with the sensor. Connect the sensor's wires to the corresponding terminals on the data logger, ensuring that the power, ground, and signal wires are correctly matched. Refer to the data logger's manual for specific terminal assignments.

What is the best way to calibrate the HMP60 sensor?

The HMP60 sensor is factory-calibrated, but for field calibration, it's recommended to use a reference meter and perform a two-point calibration. This involves placing the sensor in environments with known humidity levels and adjusting the sensor output accordingly.

How can I troubleshoot if the HMP60 sensor is not providing data?

Check the power supply to ensure the sensor is receiving adequate voltage. Verify all wiring connections are secure and correct. Inspect the data logger configuration to ensure it is set up to read the correct channel. If issues persist, try using a different data channel or replacing the cable.

What maintenance is required for the HMP60 sensor?

Regularly inspect the sensor for physical damage and clean the radiation shield if used. Replace the filter cap periodically to ensure accurate measurements, especially in dusty or dirty environments. Perform periodic sensor checks with a reference meter for calibration.

Can the HMP60 sensor be used in extreme weather conditions?

The HMP60 sensor is designed for a broad range of temperatures, but it should not be exposed to conditions beyond its specified limits. Using it with an appropriate radiation shield will help protect it from direct sunlight and precipitation, enhancing performance in extreme conditions.

How can I extend the life of my HMP60 sensor?

To extend the life of your HMP60 sensor, ensure it is installed with a radiation shield to protect it from direct sunlight and precipitation. Regularly check and clean the sensor, and replace the filter cap as needed. Store the sensor in a dry, controlled environment when not in use.

What are the common issues faced with the HMP60 sensor and how can they be resolved?

Common issues include inaccurate readings due to dirt accumulation or a contaminated filter cap. These can be resolved by cleaning and replacing the filter cap. Connection issues can be addressed by checking and securing all wiring. Calibration drift can be corrected with regular calibration checks.

How do I interpret the data output from the HMP60 sensor?

The HMP60 sensor outputs data in voltage that corresponds to relative humidity and temperature. This data is typically interpreted by the data logger, which converts the voltage to readable units. Refer to your data logger's manual for details on setting up measurement equations.

Is it possible to integrate the HMP60 sensor with other systems?

Yes, the HMP60 sensor can be integrated with various systems using compatible data loggers or controllers that accept analog voltage inputs. Ensure that the systems are configured to interpret the sensor's output correctly.

What should I do if the HMP60 sensor shows erratic data?

Check for loose or corroded connections, as these can cause erratic data. Inspect the sensor for moisture ingress or damage. If the environment is particularly harsh, consider using a more robust protective enclosure or replacing the sensor. Perform a calibration check to ensure accuracy.
