Constant temperature and humidity test chamber can meet the testing requirements of electronic products

The role of the constant temperature and humidity test chamber is to provide high temperature, low temperature, constant temperature, constant humidity, alternating hot and humid test environment, and meet the requirements of relevant standards to test chamber, the whole machine is mainly suitable for electrical and electronic products and components for cold test, the temperature and humidity changes or upheaval adaptability under the condition of test; Especially designed for electronic, electrical products environmental simulation temperature and humidity test. Constant temperature and humidity test chamber system using advanced environmental model technology design and manufacturing, products reach the domestic advanced level. The energy regulation technology, energy saving design, good sealing, high strength, easy to clean, accord with the international standardization of aesthetic monolithic structure body; With the features of easy operation, high degree of automation control system, the system runs stably, trouble-free operation time is long, etc. Constant temperature and humidity test chamber materials used in the detection performance under various environmental equipment and testing various materials heat-resistant, hardy and resistant to dry and wet resistance can. Suitable for electronics, electrical appliances, communications, instrumentation, vehicles, plastic products, metal, food, chemical, building materials, medical, aerospace and other products with the quality of detection, the main difference is that different temperature and humidity, can be achieved by generating temperature would be different. Heating system is relatively simple in the constant temperature and humidity test chamber, it is mainly composed of high power resistance wire and heating equipment, as a result of the experiment box require heating rate is bigger, the heating power of experiment box therefore is large, and at the bottom of the experiment box will also have a heater. Refrigeration system is a key part of the constant temperature and humidity test chamber, usually in the refrigeration machine equipment cooling methods and assisted the liquid nitrogen refrigeration, the refrigeration machine adopts steam refrigeration, tightening their secondary by tightening machine, condenser, throttle body and evaporator, due to the temperature of high temperature to reach - our experiment 55 ℃, single stage refrigeration is difficult to meet the meet the requirements, thus experiment box of ordinary adopted cascade refrigeration cooling way. Constant temperature and humidity test chamber humidity into humidification and dehumidification two sub-systems, humidification way with wet steam humidification, humidification, humidification water plate, ultrasonic and so on a variety of ways, dehumidifying ways has refrigeration dehumidification and boring dehumidification machine two kinds, one was dehumidifying principle of cooling dehumidification machine to air cooled below the dew point temperature, the precipitation is greater than the saturated moisture content of the water vapor condenses, reduces the humidity, is currently the most common way of dehumidification. Control system is constant temperature and humidity test cases in the control center, control system basically fall into the category of software, it determines the heating rate of the constant temperature and humidity test chamber, precision, temperature and other important goals. Now device controller are mostly adopts PID control, there are also less parts adopt PID control method combined with fuzzy control. Constant temperature and humidity test chamber of the sensor is mainly temperature and humidity sensor, its role is judgment test the temperature in the oven, the temperature sensor is used platinum electrical group and thermocouple. There are two kinds of humidity measurement method: dry bulb thermometer and solid-state electronic sensor indirect measurement method. Due to the wet and dry bulb method measuring accuracy is not high, today's experiment box is gradually to solid instead of wet and dry bulb sensor to stop the humidity measurement. The interpretation of the above is the constant temperature and humidity test chamber can meet the testing requirements of electronic products, hope can help you, if you want to learn more about information of constant temperature and humidity test chamber, welcome to the online consulting service or call the company service hotline ( Website top right corner) For consultation, we will wholeheartedly provide high quality service for you!
