Overview
HZAOC GDJS-150E high and low temperature alternating damping heat test chamber is suitable for investigating the moisture resistance of electrical and electronic products, components, parts and materials under different temperature and humidity conditions, and can be used as a storage, transportation and use in high and low temperature environment adaptability test.
Features
1. The box adopts the overall structure, the inner side is 1.0mm SUS304B stainless steel plate, the outer side is 1.0mm Cold rolled steel plate sprayed, and the thermal insulation material is ultra-fine Glass thermal insulation cotton.
2. The door sealing is made of double-decked silicone rubber sealing material, the observation window is a multi-layer conductive film tempered hollow Glass, and the built-in special heating wire is frost-proof and lighting.
3. The side of the box is equipped with φ 50mm test hole, and the stopper is silicone rubber low foam material, which has both high and low temperature resistance and thermal insulation efficiency.
4. The heater adopts a porcelain frame nickel-chrome wire electric heater, which has little thermal inertia, long service life, and stable and reliable control.
5. The humidification system adopts steam boiler electric heating and humidification method, armored electric heating tube, with water level control and anti-dry burning device.
6. The control system adopts LCD Touchscreen temperature and humidity controller, equipped with PT100 Temperature Sensor, solid state relay zero-crossing trigger to improve control accuracy.
7. Safety protection measures include phase loss protection, phase sequence error protection, phase voltage uneven protection, fan overload protection, over-temperature power failure protection, leakage protection, etc.
8. Independent over-temperature protectors and interlocking devices ensure equipment safety, and the heating and humidification system cannot be started when the circulating fan is not started or overloaded.
Principle
The test chamber adjusts the temperature and humidity in the working room through the evaporator, electric heater, humidifier and fan in the air conditioning cabinet. The temperature transducer is placed in a trend, and the control system precisely controls the heating and humidification process through PID signals and solid-state relays to realize a stable temperature and humidity environment simulation.
Applications
Electrical and electronic products, components, parts and materials moisture resistance test, high and low temperature environment storage adaptability test, transportation adaptability test, use adaptability test
Standards
GB/T2423.3-2001、GB/T5170.5-96、GB/T10586-89
Notice
• Power frequency check meets AC380V requirements before use.
• Make sure the circulating fan starts normally, otherwise the heating and humidification system will not work.
• Regularly check the water level control device and heater anti-dry burning device to prevent damage to the equipment.
• Pay attention to the heating wire and lighting function of the observation window to ensure normal use in a low temperature environment.
• Follow safety protection measures during maintenance, such as phase loss, over-temperature power failure and other protection functions.
• The test hole stopper needs to be kept intact to maintain the thermal insulation efficiency.
