Description

Technical Field

[0001] This invention belongs to the field of sensor technology, specifically relating to a composite probe for monitoring temperature and humidity in high-temperature, high-humidity, and salt spray environments. Background Technology

[0002] A temperature and humidity sensor is a device that converts temperature and humidity measurements into easily measurable and processable electrical signals. It generally consists of two parts: a data acquisition unit and a test probe. After measuring the temperature and humidity, the test probe converts the data into an electrical signal or other desired form of information according to a specific rule and transmits it to the data acquisition unit, completing the temperature and humidity measurement. The test probe is a crucial component of the temperature and humidity sensor; its accuracy, stability, and sensitivity significantly impact the sensor's measurement accuracy and stability.

[0003] Existing temperature and humidity sensors or probes are mostly used in air or ordinary industrial and natural environments. They are easily damaged in high-temperature, high-humidity, and salt spray environments, which greatly reduces the reliability of temperature and humidity detection. For example, the China National Intellectual Property Administration has disclosed a temperature and humidity detection device (201210557553.8), which describes a temperature and humidity detection device applied to portable devices such as mobile phones. Patents such as 201620071455.7, 201611143749.7, and 201720465067.1 describe wireless transmission temperature and humidity sensors, all of which are used in natural environments or cold chain industrial environments.

[0004] The corrosion resistance of equipment is a crucial indicator of its environmental adaptability, and salt spray testing is an important test for evaluating its corrosion resistance. Salt spray testing is primarily used to assess the environmental adaptability of equipment exposed to high-temperature, high-humidity environments with high salt content, to determine the effectiveness of its protective and functional layers, and to test the impact on physical and electrical properties. During the test, changes in temperature and humidity directly affect the results. Therefore, strict requirements are placed on the temperature and humidity changes during salt spray testing, especially for large-scale salt spray testing facilities used for testing entire military systems or equipment. These facilities require numerous temperature and humidity sensors to monitor the test space in real time.

[0005] Existing temperature and humidity sensor probes cannot be used for extended periods in high-temperature, high-humidity, and salt spray environments, thus failing to meet the aforementioned requirements. Summary of the Invention

[0006] To overcome the shortcomings of existing technologies, this invention provides a composite probe for monitoring temperature and humidity in high-temperature and high-humidity salt spray environments. It primarily addresses the problem that existing temperature and humidity sensor probes cannot be used for extended periods in such environments. The probe includes a locking clamp, a housing, a connecting base, a temperature measuring element, a humidity measuring element, a protective cover, and a filter. The fixed ends of the temperature and humidity measuring elements are mounted on the connecting base. One end of the connecting base is threaded to one end of the housing, and the other end is fitted with the protective cover. This invention features a simple and compact structure, facilitating installation and use. It is suitable for long-term, highly reliable monitoring of temperature and humidity in high-temperature and high-humidity salt spray testing environments.

[0028] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0029] The purpose of this invention is to address the shortcomings of the existing technology by providing a composite temperature and humidity sensor probe that can be used reliably for extended periods in high-temperature and high-humidity salt spray environments. This solves the problem of real-time monitoring and detection of temperature and humidity during salt spray testing, providing a foundation for precise temperature and humidity control in large spaces during salt spray testing. The key technology to achieve this objective is to install the temperature and humidity measuring elements inside a protective cover with a filter. The technical solution is as follows:

[0030] A composite probe for monitoring temperature and humidity in high-temperature and high-humidity salt spray environments includes a locking clamp 1, a housing 2, a connecting base 3, a temperature measuring element 4, a humidity measuring element 5, a housing protective cover 6, and a filter screen 7. The fixed ends of the temperature measuring element 4 and the humidity measuring element 5 are mounted on the connecting base 3. One end of the connecting base 3 is threaded to one end of the housing, and the other end of the connecting base is equipped with the housing protective cover 6.

[0031] The outer shell 2 is a threaded cylindrical cavity. The connecting wires of the temperature measuring element 4 and the humidity measuring element 5 pass through the cavity of the outer shell to the electrical wire interface of the outer shell. The interface is equipped with a wire locking clamp 1.

[0032] The outer casing 6 is a threaded thin-walled cylinder, and a filter screen 7 is provided at the end of the outer casing 6.

[0033] The connecting base 3 has a structure with a protrusion in the middle and threads at both ends, and the protruding part in the middle has two insertion holes.

[0034] Example:

[0035] like Figures 1-3 As shown, the present invention provides a composite probe for temperature and humidity sensors, including a locking clamp 1, a housing 2, a temperature measuring element 4, a humidity measuring element 5, a connecting base 3, and a housing protective cover 6. The fixed ends of the temperature measuring element 4 and the humidity measuring element 5 are mounted on the connecting base 3. One end of the connecting base 3 is threadedly connected to one end of the housing 2, and the other end is threadedly fitted with the housing protective cover 6.

[0036] The locking clamp 1 is threadedly connected to the outer casing 2. The outer casing 2 is a threaded cylindrical cavity, through which the measuring element connection wires run. The connecting base 3 is threadedly connected to the outer casing 2. The outer casing protective cover 6 is a threaded thin-walled cylinder, threadedly connected to the connecting base 3. The filter screen 7 is inserted into the opening at the end of the outer casing protective cover 6.

[0037] The outer shell 2 is a threaded cylindrical cavity. The connecting wires of the temperature measuring element 4 and the humidity measuring element 5 pass through the cavity of the outer shell 2 and exit through the electrical wire interface of the outer shell 2. The interface is equipped with a wire locking clamp 1.

[0038] The connecting base 3 has a structure with a protrusion in the middle and threads at both ends, and the protruding part in the middle has two insertion holes.

[0039] Temperature measuring element 4 and humidity measuring element 5 are inserted into connecting base 3 and connected to connecting base 3 by sealant.

[0040] The outer casing 6 is a threaded thin-walled cylinder, and a filter screen 7 is provided at the end of the outer casing 6.

[0041] The filter screen 7 is made of sponge material, which can filter out water droplets and prevent saturated gas from condensing; the wire clamp 1 is used to fix the signal wire harness of the temperature measuring element 4 and the humidity measuring element 5.

[0042] When using this probe for measurement, simply place it in the environment to be measured.

[0043] In this embodiment, in a saturated salt spray environment, the humidity sensor may fail due to salt spray condensation. This invention designs a protective cover 6 and a filter 7 to protect the humidity sensor. The filter 7 prevents the formation of droplets from saturated salt spray on the surface of the humidity sensor and does not alter the ambient temperature and humidity, effectively protecting the temperature measuring element 4 and humidity measuring element 5 inside the protective cover, preventing damage due to fogging inside the protective cover 6 and the outer shell 2. Therefore, by designing the protective cover 6 and the filter structure 7, the composite probe achieves salt spray resistance.

[0044] The composite probe was placed in the salt spray test chamber, and the temperature and humidity of the test environment were collected. After data visualization analysis, the resulting data curves are shown below. Figure 4 .from Figure 4 As can be seen, this utility model can continuously collect temperature and humidity data of salt spray environments, helping practitioners to evaluate the quality of temperature and humidity control in environmental tests and adjust test parameters as needed.
