Industrial flame-proof platinum resistance is a kind of temperature sensor.A wide application in industrial control system, through the temperature sensor, can control the temperature of the object parameter into electrical signal, passed to the display, record and monitoring instrument, testing, adjusting and control law in the system.In chemical plant, the production site is often accompanied by various kinds of flammable, explosive chemical gas, steam, if use common platinum resistance is not safe, easy to environment caused by gas explosion.On these occasions, therefore, must use the flame-proof thermocouples as temperature sensor, the factory production of flame-proof platinum resistance product is used in d ii bt4 ~ d category ii ct6 temperature interval explosive gases in dangerous places. Our factory produce flame-proof thermocouple adopts imported components for thermal components, its technical performance in line with the zby301-85 industrial platinum electrical technical conditions and indexing table.At the same time products conform to the general requirements for explosive environment with explosion-proof electrical equipment, gb3836.2 gb3836.1-83-83 standard.
Mixer main technical indicators
Range specifications
Explosion-proof grade groups: d ii bt4 or d ct4 ii;D ii ii ct6 bt6 or d
Enclosure protection grade: ip54
The principle of structure
Flame-proof thermal resistance and prefabricated thermal resistance of the structure, principle of basic same, explosive SuoOu other is product of junction box (shell
) on the design adopts the structure of the flameproof special, junction box with high strength aluminum alloy die casting, and have enough internal space, the wall
Thickness and mechanical strength, thermal stability of the rubber sealing ring conform to the state explosion protection standard.So when the explosive mixture inside the junction box
Body exploded, it won't destroy junction box, and the resulting heat cannot spread outward - explosive.
The adoption of the flameproof special product structure, make the product completely conforms to use in d ii bt4 to d ii ct6 blast temperature
Group interval range, as long as the user strictly abide by the regulations regarding the use of the product, product can achieve reliable explosion-proof effect.
Electrical equipment's type, level and temperature category description:
Electrical equipment is divided into two categories: type I, the coal mine electrical equipment;
Class ii - use electrical equipment factory
Explosion-proof grade
Flame-proof heat resistance level of explosion-proof mechanical its biggest security clearance is suitable for explosive gas mixture is divided into a, b, c level 3.
Temperature classes
Flame-proof tropical resistance according to the exposed part of the maximum surface temperature can be divided into temperature classes t1 ~ t6 six groups.
