Heraeus Electro-Nite Molten Metal Measurement and Sensing Technologies Architecture

Heraeus Electro-Nite International N.V. designs and manufactures precision immersion sensors, sampling probes, and metallurgical measurement systems for molten steel, iron, aluminum, and copper production.

The core portfolio features Positherm single-use immersion thermocouples, Celox electrochemical oxygen probes, and Hydris automated direct hydrogen measurement instrumentation.

For continuous tundish monitoring in continuous pouring operations, the company provides robust CasTemp and Contitherm sensing assemblies.

Steelmaking basic oxygen furnace operations utilize QuiK-Tap drop sensors, while iron foundries deploy QuiK-Cup thermal analysis cups and DigiTemp-E microprocessor units paired with QUBE wireless links.

Technical Selection Procedures and Maintenance Guidelines for Metallurgy Instrumentation

Selection of immersion temperature sensors requires evaluation of thermocouple calibration types S, R, and B alongside cardboard immersion sheath lengths up to 1700 mm.

For active oxygen and carbon determination, Celox immersion probes with stabilized zirconia solid electrolytes provide rapid electrochemical readings across secondary metallurgy ladles and vacuum degassers.

Periodic maintenance of secondary instrumentation DigiTemp and Digilance encompasses terminal insulation resistance verification, contact receptacle inspection, and carrier gas pneumatic line sealing.
