Temperature Humidity and Low-pressure Altitude Test Chambers for aerospace test
Introduction:
Temperature Humidity and Low-pressure Altitude Test Chambers for aerospace test is used in different industries like the instruments and meters, electrical products, materials, spare parts, equipment, etc, but mainly in aviation, aerospace, information, electronics and other industries. This machine can be operated at a low pressure, high temperature, low temperature, under the effect of single factor or multiple conditions at the same time. Simulation of high-altitude conditions like might be found in mountainous regions. Test for electric performance parameters of the specimen.

| 【Working Principle】 | |
| Pneumatic Working Principle | The central controller detects the real-time signal from the sensing element and compares it with the set pressure signal to obtain a comparison signal. The control device outputs a bit switch signal to control the opening and closing of the vacuum pump valve and the high vacuum pneumatic ball valve. To achieve the purpose of automatic control pressure. Restore the pressure process, when the need to restore pressure, then open the high vacuum baffle valve, filled by the inflatable joints required gas |
| Temperature Working Principle | The central control system is amplified according to the temperature signal collected in the box, the analog / digital conversion, the non-linear correction and the temperature set value (target value) are compared, the resulting deviation signal by the PID operation, the output adjustment signal automatically Control the size of the output power of the heater, so that the heating and heat dissipation in the laboratory to achieve a dynamic balance, and ultimately achieve the purpose of constant temperature. |

FAQ:
1. Do you offer after-sales service? How can I ask for that? And how about the warranty?
Every machine from our factory has a 14-month warranty after shipment. Generally, we offer 12 months for the FREE maintenance, while considering of sea transportation, we can extend 2 months for our customers. If your machine doesn’t work, you can send E-mail to us and we will try our best to find the problem by email or skype video chat if neccesary. After confirmation of the problem, we can send you new spare parts or provide on-site repair.
2. What’s the delivery term?
At most of time, we have stock in the factory. If there is no
stock, normally, the delivery
time is 15-20 working days after deposit receipt. If you are in urgent need, we can consider
making a special arrangement for you.
3. Do you accept customization service? Can I have my logo on the
machine?
Yes, of course. We can not only offer standard machines, but also
customized
machines according to your requirements. And we can also put your logo on the machine.
Please feel FREE to contact us if you have any needs.
