Detailed introduction of exhaust system software
The temperature adjustment of the high-low Temperature Test Chamber is based on the temperature sensor embedded in the shell, which collects data and is regulated by the temperature controller (small amount of information CPU), connected to the gas heating module to complete the temperature rise, or adjusting the refrigeration relay to reduce the temperature of the chamber to achieve control desired temperature. The environmental humidity adjustment of the constant temperature and Humidity Chamber is based on the temperature sensor of the fuselage, and the data is collected, adjusted, and connected to the stainless steel sink heating element through the humidity controller (small amount of information CPU).
In the sales market, the temperature uniformity of short-axis motors of the same familiar brand produced by some manufacturers is not up to standard, which involves technical specifications. The high-low Temperature Test Chambers used for production all meet the specification requirements. Tripartite Metrology Institute International Certification. In addition, customers are reminded not to use their own company's temperature sensor to calibrate the temperature of the environmental Test Chamber. This is forbidden. If temperature correction is required, verify factory accuracy with a third-party measurement agency.
Cryostat Frequently Asked Questions
1. Liquid substances (pure water, ethanol, simethicone) should be added to the tank before the cryostat is used. The liquid level of the substance should be less than 20mm from the operating table, otherwise the electric heater will be damaged when plugged in.
2. The liquid substance used in the cryostat should meet the following standards: when the working temperature is lower than 5°C, the liquid substance is generally ethanol; when the working temperature is 5-85°C, the liquid substance is generally water; when the working temperature is 85°C-95°C 15% vaseline solution can be used for liquid substances, which can reduce the volatilization of water; when the working temperature is higher than 95°C, the liquid substance generally uses oil, and the open-cup flash point value of the selected finished oil should be that the working temperature is higher than 50°C; usually use A lower viscosity simethicone.
3. Switching power supply: 380V50Hz, the rated power of the power supply should exceed the total output power of the instrument and equipment, and the switching power supply needs to have a good "grounding device" equipment;
Frequently asked questions about constant temperature and humidity Test Chamber staff
First of all, before doing the experiment, the actual operator must understand the structure, characteristics, characteristics, experimental range, and acceptable limit range of the experimental equipment. When doing natural environment experiments, it is necessary to understand the sample characteristics, experimental standards, experimental procedures, and experimental techniques required for the experiment, as well as the technical characteristics of the experimental equipment used, especially the characteristics of the actual operation and control panel. In addition, due to the differences in the application of various natural environment experimental equipment, technical operators need to carefully read the actual operation manuals of commonly used experimental equipment before using mechanical equipment to prevent errors caused by improper operation. Abnormal operation of experimental equipment, destruction of experimental samples, errors in experimental data and information, etc.
The second is to effectively select experimental equipment. In order to ensure the normal progress of all experiments, appropriate experimental equipment should be selected according to the different conditions of the experimental samples, and an effective ratio should be maintained between the reasonable capacity of the experimental samples and the environmental Test Chamber. 3. For natural environment experiments where substances are often added in experiments, appropriate additions should be made in accordance with the experimental regulations.
