The Reckmann GmbH Glass Thermocouple with Neck Tube & Platinum Sleeve is a premier, heavy-duty industrial temperature sensor engineered and manufactured directly by Reckmann GmbH Sensor & Messtechnik (Germany). Specifically developed to master the extreme operating demands of the glass manufacturing industry, this specialized thermocouple provides ultra-precise, drift-free thermal monitoring inside float glass furnaces, container glass forehearths, feeder bowls, and optical glass melting vessels where conventional metallic protection tubes suffer immediate catastrophic failure from liquid glass corrosion and hydrodynamic erosion.

The construction of the Reckmann Glass TC integrates four advanced engineering components:
1. Precious Metal Thermocouple Insert: High-accuracy Type S (Pt10%Rh-Pt), Type R (Pt13%Rh-Pt), or Type B (Pt30%Rh-Pt6%Rh) thermocouple elements adhering to Class 1 tolerances per IEC 60584 / DIN EN 60584, delivering uncompromised signal fidelity and thermal stability.
2. Precious Metal Outer Protection Thimble (Platinum / PtRh Sleeve): The immersion tip exposed to fluid glass melt is armored with a seamless, high-purity Platinum or Platinum-Rhodium alloy sleeve (Pt, PtRh10, PtRh20, or dispersion-strengthened DPH Platinum). This sleeve is impervious to liquid glass fluxing, chemical dissolution, and oxidative attacks at temperatures exceeding 1500°C.
3. Inner Ceramic Protection Tube: Fabricated from high-purity recrystallized Alumina ceramic Alsint 99.7 (Type C 799, >99.7% Al2O3), providing exceptional electrical insulation, thermal shock resistance, and zero chemical contamination of the internal thermocouple wires.
4. Structural Neck Tube & Connection Head: A robust heat-resistant metallic neck tube (Inconel / Heat-resistant Stainless Steel) isolates thermal transfer between the furnace crown and the aluminum or stainless steel terminal head (Form B / Form A, rated IP65/IP66), accommodating ceramic terminal blocks or built-in 4-20mA / HART temperature transmitters.

Manufactured under stringent German quality assurance standards, the Reckmann Glass TC provides long operational life, minimizes furnace downtime, and optimizes energy consumption across critical glass production lines worldwide.
