In the era of rapid development of modern science and technology, temperature measurement and control has become an indispensable part of scientific research, industry and daily life. As a kind of temperature sensor, thermistor is widely used in various temperature measurement scenarios because of its fast response, small size, low price and other advantages. The thermistor acquisition instrument, as the device of thermistor signal acquisition, processing and display, its accuracy, stability and ease of use directly affect the accuracy and efficiency of temperature measurement. This paper will introduce a high-precision, high-stability thermistor acquisition instrument in detail, and analyze its technical characteristics, application scenarios and advantages.
Technical features
High-precision 24-bit AD converter
The thermistor acquisition instrument uses a high-precision 24-bit high-resolution analog-to-digital converter (AD converter), which can accurately capture the weak resistance changes, thus ensuring the high accuracy of temperature measurement. 24-bit AD converter means higher resolution and lower quantization error in the conversion process, making the measurement results more accurate and reliable.
High precision, low temperature drift reference device
In order to ensure the stability of the measurement, a high precision and low temperature drift reference device is built in the acquisition instrument. Low temperature drift means that the output value of the reference device changes very little when the temperature changes, thus reducing the impact of temperature changes on the measurement accuracy. This design enables the acquisition instrument to maintain stable measurement performance in a variety of temperature environments.
Advanced data processing algorithm
In addition to the high precision design of hardware, the acquisition instrument also uses advanced data sampling, filtering and sorting processing algorithms. These algorithms can effectively suppress the noise interference and improve the reliability and accuracy of the data. At the same time, through the sorting processing algorithm, the outliers can be further eliminated to ensure the stability and consistency of the measurement results.
Low power design
In order to meet the requirements of long-time and continuous measurement, the acquisition instrument is designed with low power consumption. By optimizing the circuit structure and software algorithm, the power consumption is reduced, and the service life of the device and the battery life are prolonged while maintaining high precision and high stability.
Application scenario
Environmental test equipment
In environmental test equipment, such as high and low temperature test chamber, temperature and humidity monitoring system, the thermistor acquisition instrument can monitor and record the temperature and humidity changes in the test chamber in real time, and provide accurate data support for scientific researchers.
Refrigerator and low temperature refrigerator
In the food, medicine and other industries, the temperature control of refrigerated cabinets and low-temperature refrigerators is very important. Thermistor acquisition instrument can monitor the temperature of these devices in real time to ensure that food, medicine and other items are stored at a suitable temperature.
Medical sterilization device
In the pharmaceutical industry, the temperature control of the sterilization device is directly related to the quality and safety of the product. The thermistor acquisition instrument can monitor the temperature change of the sterilization device in real time to ensure that the sterilization process reaches the predetermined temperature and time requirements.
Intelligent Equipment and Scientific Instruments
In the fields of intelligent equipment and scientific instruments, temperature measurement and control is also an indispensable link. Thermistor acquisition instrument has become the preferred equipment for temperature measurement in these areas because of its high accuracy, high stability and ease of use.
Advantage analysis

By using high precision 24-bit AD converter, high precision low temperature drift reference device and advanced data processing algorithm, the acquisition instrument has excellent performance in measurement accuracy and stability. It can provide accurate and reliable measurement results in both high and low temperature environments.
Portability and ease of use
The acquisition instrument is designed to be compact and portable, and can be carried by hand, which is convenient for users to measure in different occasions. At the same time, its operation interface is friendly and the menu is simple and easy to use, so both professionals and novices can get started quickly.
Multi-channel design
The acquisition instrument supports multi-chan nel design, and users can monitor multiple temperature points or samples at the same time, which greatly improves the work efficiency and measurement accuracy. This multi-channel design not only saves time and cost, but also facilitates the work of the user.
Powerful data processing capability
Windows-based data acquisition software, such as the 161XA DAQ data acquisition software, enables users to easily collect and analyze measurement results using a PC. The software supports real-time display, trend drawing, channel overrun alarm and other functions, and provides users with comprehensive data processing and analysis capabilities.
With the characteristics of high precision, high stability, portability and ease of use, the thermistor acquisition instrument has a wide application prospect in the field of temperature measurement. Whether in scientific research experiments, industrial production or daily life, it can provide users with accurate and reliable temperature measurement solutions. With the continuous progress of science and technology and the continuous expansion of application scenarios, the performance and function of thermistor acquisition instrument will continue to improve and enhance, providing more powerful support for temperature measurement and control in all walks of life.
