粉塵層點火溫度測試儀

在易燃粉塵顆粒可能積聚的行業中，粉塵層自燃是一個很大的風險。了解導致粉塵層點燃的熱表面的最低溫度，可為加工工業的風險分析、安全規劃和火災或爆炸預防提供重要資訊。
 

應用

在使用易燃液體的行業和技術中，自燃溫度的測量是危險分析的重要參數。暴露在高溫下的液體材料可能會產生易燃蒸汽，點燃後可能會導致爆炸。AIT 551 是對新技術進行危險分析、操作安全控制、研究和開發的必要工具。所得結果用於液體化學品的溫度等級分類。

合規

• EN 50281-2-1 Methods of determining minimum ignition temperature
• ASTM E2021 Hot-Surface Ignition Temperature of Dust Layers

The LIT 400™ (Dust Layer Ignition Temperature Tester) is used for determination of minimum temperature of a hot surface leading to thermal degradation or ignition of dust layers of a defined thickness.

APPLICATIONS

Spontaneous ignition of dust layers is a great risk in industries where flammable dust particles can get accumulated. Knowledge of minimum temperature of a hot surface which will lead to dust layer ignition provides important information for risk analysis, safety planning and prevention of fires or explosions in process industries.
 

ADVANTAGES & FEATURES Hot surface working temperature range up to 450 °C Stable temperature conditions ± 2 °C Hotplates designed with a non-corrosive abrasion-resistant surface or aluminum plate Four types of stainless steel rings as sample holders for the dust layers Stainless steel set for easy dosing and cleaning Recording, archiving and data analysis on PC Robust stainless steel case
