Explosion-proof

When there's oxygen(air), explosive matter and explosion leading source, such as electronic light, flaming surface), the explosion will happen. The explosion proof scale must control at least one of these matters to achieve the aim of anti-explosion. This is the triangle principle of the explosion.

YUBO owns its specializing explosion proof laboratory, and the explosion proof technical staff devotes in R & D to develop different explosion proof scales suitable for different environment. In all the aspects of designing, manufacturing, site installing, user training, distributor training and the theory of explosion proof scale, YUBO has an unique industry advantage.

All the explosion-proof products are designed, produced, assembled and inspected according to GB3836 explosion proof standard, which ensures high reliability and accuracy of the explosion-proof scales.

Explosion proof class: Instinct safe ExibllCT4/T5, Explosion insulated ExiadllBT5, Multiplex explosion proof ExiallCT6
Explosion proof products: Explosion proof truck scale, Explosion proof platform scale, Explosion proof bench scale, Explosion proof weighing system, Explosion proof accessories
Explosion proof mode: Instinct safe, Explosion insulated, Multiplex explosion proof

Please pay attention to the following when selecting the explosion proof scale:
1.Firstly, you should make sure the dangerous material in the application site, and its covering area.
2.Secondly, make sure the explosion proof mode according to variety, class and temperature.
3.Gas explosion proof is completely different from dust explosion proof. Explosion proof for coal mine is completely different from standard explosion proof.
4.The installation and application of the explosion proof should be performed strictly complying with the construction criterion.
5. Safety barrier and other related equipments are needed when instinct safe equipments connected with equipments which are not instinct safe.

Main configuration of Explosion-proof scale

1. Instinct safe.

 It is major used on explosion-proof bench scale and explosion-proof floor scale.

Explosion-proof Mode 

There are 3 types of explosion-proof in YUBO Scale Company: Instinct safe,  Explosion insulated,  Multiplex explosion proof
1. Instinct safe
Measures of Instinct safe explosion proof are adopted for all parts of electronic scale. Instinct safe is suitable for vast majority of explosive environments.

2. Explosion insulated
Explosion proof box is adopted for some parts of electronic scale in order to anti-explosion by isolation, but other parts and interfaces which are out of box still need instinct safe process.

3. Multiplex explosion proof
Some parts of the electronic scale are placed in the danger zone, while the others are placed in safe area. Generally, the load cell, junction box and so on which are in danger zone should be instinct safe, then connect with common indicator through associated equipment in safe area. Because the operating is in  safe area, so the configuration of this mode is very flexible.
