3、 Characteristics and working principle of splash proof structure

1. Anti splash core design

Dual protection system: fire-resistant paper tube+splash proof coating+aluminum slag cap+internal ceramic insulation, isolating high temperature and slag splashing Heraeus Electro Nite

Streamlined head: reduces slag adhesion and improves measurement accuracy

Quick connection interface: Standard measuring gun interface, easy to insert into Heraeus measuring gun, tight and stable connection

Integrated unit: No additional preparation required before measurement, plug and play, improving operational efficiency

2. Working principle

Based on thermoelectric effect: When the hot end of an S-type thermocouple (platinum rhodium 10 platinum) is immersed in molten metal, a temperature difference electromotive force is generated between the hot end and the cold end, which is transmitted to the thermometer through a compensation cable and converted into accurate temperature readings. The splash proof design ensures that the thermocouple can still function properly in harsh environments and obtain stable measurement results for Heraeus Electro Nite.

4、 Suggestions for matching application scenarios and selection
