In the industrial field, the quality of products and the control of the entire process are greatly affected. This is because the insulation and heat transfer effects of the temperature system itself are very complex. Under the condition of reaching thermal equilibrium, it is believed that the temperature gradient of a small volume at the center of its internal mass is sufficiently balanced. This is one of the important reasons why the temperature calibration source has a large volume.

In addition, the heat transfer of a temperature system is also very complex, often completed through heat conduction, convection, and radiation. It can be imagined that it is almost impossible to suddenly change its temperature and reach thermal equilibrium. This is because conventional temperature calibration sources have a large volume and long rise and fall times to ensure a certain degree of temperature field uniformity, resulting in time-consuming, labor-intensive, and expensive inspection, maintenance, and calibration of temperature measurement systems in the industrial field, and the reliability of the system is affected by multiple disassembly and installation of temperature probes. The industrial field hopes to have a small and lightweight portable temperature calibration source (constant temperature bath) similar to a pressure calibrator. However, this small and portable temperature calibrator must overcome the drawbacks of poor temperature field uniformity and stability caused by reduced volume. In order to achieve stable temperature rise and fall in a short period of time, there must be close coordination between heating and cooling, which can reduce the heating and cooling time. Cooling and heating in a miniaturized constant temperature bath also affect the uniformity of the temperature field,

Therefore, taking into account various factors, achieving a portable temperature calibrator with ultra small size and a certain degree of rapid temperature rise and fall is a field application that has been explored and developed for many years in the field of temperature measurement technologyinstrumentThe company's ultra small temperature calibrator, Z, overcomes the technical difficulties caused by ultra miniaturization to the greatest extent possible, allowing users to carry it to every corner of the industrial site to perform on-site calibration operations on the temperature probes that need to be inspected, repaired, and calibrated, eliminating the need to disassemble and retrieve them to the laboratory for comparison. Z also overcomes the technical difficulties caused by ultra miniaturization to the greatest extent possible, allowing users to carry it to every corner of the industrial site to perform on-site calibration operations on the temperature probes that need to be inspected, repaired, and calibrated, eliminating the hassle of disassembling and retrieving them back to the laboratory for comparison calibration, and reinstalling them to the original system. This can greatly improve work efficiency, save time, increase equipment and system availability, and provide automatic control for the site. The engineer provided excellent maintenance and calibration methods. The series of ultra small temperature calibrators breaks away from the traditional temperature calibration mode and has a wide range of applications, covering every step of temperature measurement and calibration in the industrial field. It also provides an adjustable analog temperature source, which provides an important inspection method for improving process control level, product quality assurance, and preventing automatic protection setting errors and fault finding in industrial processes. Especially for the constant value inspection of temperature switches, it can achieve fast, accurate, and convenient results. Its application areas involve: petrochemicals: oil production, oil pipelines, petrochemical plants, and refineries.
