Description

Technical Field

[0001] The utility model relates to the technical field of sensor probes, in particular to a liquid testing sensor probe structure. Background Art

[0002] The probe of the liquid test sensor is its key component, which directly affects the measurement accuracy and stability of the sensor in the liquid environment. The probe is usually made of corrosion-resistant materials such as stainless steel or special plastics to resist chemical erosion and physical impact in the liquid environment. Different types of probe designs vary according to the measured properties. For example, the temperature probe may be a rod-shaped metal or plastic structure, while the pH probe includes specially designed electrodes, etc., which are used to detect pressure changes in liquid pipeline systems or hydraulic equipment to ensure the safe operation of the system. The turbidity in the liquid is measured by optical methods to monitor the concentration of suspended particles and the clarity of the liquid. The design and use of the liquid test sensor probe are different due to different application scenarios. It can provide accurate and reliable liquid property data to support a variety of application needs such as automated control, quality assurance and scientific research.

[0003] When the existing liquid test sensor probe is placed in water areas with too fast flow rate for testing, the fast flow rate may cause surrounding objects or suspended matter to directly hit the sensor probe and cause physical damage. The high-speed flow of water may carry corrosive substances and increase the risk of chemical erosion of the sensor probe. The collision or chemical erosion of flowing objects may cause inaccurate measurement data of the sensor probe and affect the reliability of the test results. Utility Model Content
