Water Quality Sensor Temperature & Pressure Destructive Test

Required Equipment for Testing

• Water Quality Sensor: The subject under test, designed to measure various parameters in aquatic environments.
• Temperature & Pressure Chamber: A specialized device capable of simulating extreme conditions to test the sensor's resilience.
• Heating Furnace: Provides the necessary thermal environment to expose the sensor to high temperatures.
• Temperature Measurement Electrode: Precisely measures temperature fluctuations within the chamber.
• Pressure Measurement Electrode: Monitors pressure levels to assess the sensor's performance under stress.
• Computer for Monitoring: Equipped with software to oversee and record test data in real-time.
• Modbus Poll Software: A versatile tool for data acquisition and visualization, enabling detailed analysis of sensor performance.

Step-by-Step Testing Process

1. Equipment Installation

Follow these steps to set up the testing equipment:

1. Place the temperature & pressure chamber on the heating furnace.
2. Connect the temperature and pressure electrodes to the chamber and computer.
3. Fill the chamber with water, insert the sensor, and connect the system to the computer.

2. Modbus Poll Software Configuration

Set up the software for real-time monitoring:

• Activate the temperature measurement display unit.
• Activate the pressure measurement display unit.
• Enable the temperature-pressure curve graph.

3. Conducting the Test

Once the setup is complete, proceed as follows:

1. Turn on the heating furnace and monitor the temperature and pressure levels.
2. Maintain the temperature above 130°C and ensure stability.
3. After the test, remove the sensor and check its impedance using an impedance analyzer.
4. If the impedance value meets the standard, the sensor passes the test.

Conclusion

The temperature and pressure destructive test is a crucial method to evaluate the durability and reliability of water quality sensors. By following this structured process, manufacturers can ensure their sensors meet industry standards under extreme conditions.
