Product catalog summary

Application Furnace
In the competitive landscape of heavy clay products and refractories manufacturing, reducing production costs and enhancing efficiency are critical. Key operational parameters like energy consumption and reject rates are influenced by the kiln temperature profile, necessitating precise temperature monitoring during the firing cycle.

Advantages of Non-contact Temperature Measurement
Modern kilns are increasingly equipped with pyrometers, which measure temperature via infrared radiation, offering more accurate readings than thermocouples. Pyrometers provide immediate temperature feedback, allowing for optimal process control and reduced fuel consumption. Unlike thermocouples, pyrometers do not suffer from sensor drift, ensuring reliable measurements and lower reject rates. Pyrometers are also cost-effective, with initial costs comparable to thermocouples but without ongoing maintenance expenses.

Pyrometer CellaTemp® PK with Mounting
The PK Series pyrometers are designed for stationary measurements in ceramic kilns, housed in stainless steel with a 4-20 mA output signal compatible with standard displays and controllers. The series includes accessories for tunnel kiln applications and offers two-colour pyrometers to mitigate signal loss from optical contamination.

Portable Instrument
The CellaPort PT series portable pyrometers are ideal for quick temperature checks, featuring focusable optics and a target marker for precise aiming. They include an ATD function for easy operation and data logging capabilities, with PC connectivity for extended analysis.

Conclusion
Pyrometers are a superior alternative to thermocouples for furnace temperature measurement, offering long-term reliability, cost savings, and reduced scrap and fuel consumption. The PK series provides stationary solutions, while the CellaPort PT series offers portable options for quick checks. Continuous investment in advanced technologies is essential for maintaining competitiveness.

Application Furnace Non-contact Temperature Measurement for Optimal Fuel Efficiency

Open the catalog to page 1

Application Furnace Furnace applications In today's international competition, a manufacturer of heavy clay products or refractories is forced to deal permanently with the reduction of production costs and the increasement of the efficiency of the production plant. I t only makes sense to influence such cost-intensive operating parameters which have the greatest savings potential: reducing energy consumption and minimizing the reject rate. The kiln temperature profile has a significant influence on the amount of fuel required and the quality of the yield. In this respect, it is of utmost importance...
