MIL STD 810G sand dust test chamber is employed to perform and test all mechanical, optical, electrical, electronic, chemistry and mechanical device devices liked to be exposed to dry processing sand or dry processing dust-laden environment. The MIL STD 810G sand dust test chamber has two functions: According to the MIL-STD-810G 510.5 Procedure I and Procedure II, Prepare the dust (< 150μm) test procedure and sand (150 to 850μm particle size) test procedure.
The purpose of dust (< 150μm) procedure: This test procedure is performed to assist measure the flexibility of equipage to resist the results of mud that will hinder openings, penetrate into cracks, crevices, bearings, and joints, and to judge the effectiveness of filters.
Sand (150 to 850μm particle size) procedure: The Sand (150 to 850μm particle size) procedure is performed to assist measure the flexibility of equipage to be hold on and operated in processing sand conditions while not degrading performance, effectiveness, responsibility, and maintainability because of abrasion (erosion) or preventive effects of huge, sharp-edged particles.

● Safety Protection System of Wewon MIL STD 810G Sand Dust Test Chamber : The security protection system is the most important for users, and setting up multi-layer protection is an important measure to protect users.
● Phase Order Protection for mil std 810g Sand Dust Test Chamber: Three-phase power is easy to be out of phase or the line sequence is opposite can let the equipment damage or test personnel accident.
●Leakage Protection: The use of unqualified heating wire or humidifying pipe is enough to cause electric shock. Overtemperature Protection: The use of controllers with poor brand quality may lead to temperature loss and fire accidents。
● Fault Protection: When one of the indicators of the equipment is abnormal, the equipment will automatically prompt the reason for alarm and the solution. At the same time, the equipment will be suspended until the maintenance personnel solve the problem.

Heating System of Wewon MIL STD 810G Sand Dust Test Chamber: Heating wire used at high frequency is very important in this system. Improper selection of Heating pipe, short service life, easy to produce funnel short circuit phenomenon, It is extremely inconvenient and distressing for users with high requirements, and seriously affects the production inspection schedule.
According to this, Wewon Environmental Chambers Co., Ltd. research and development of the latest new ceramic heating frame, ceramic materials resistant to high temperature, good insulation. No leakage short circuit, Intermediate through the German imported heating wire, wire diameter thick, high temperature resistance, resistance to dry burning.
Quartz glass tube for mil std 810g sand dust test chamber is inserted in the heating wire, the important function of which is to prevent the heating wire from becoming soft and falling when burning red, and to produce the fault phenomenon such as short circuit in the contact between the heating wire and the metal in the inner test room.
