PTCR Process Temperature Control Rings
From 560 °C (1040 °F) up to 1750 °C (3182 °F)With this data sheet we provide a general overview about PTCR. For further technical information, useful hintsand application advice for the use of Process Temperature Control Rings PTCR please refer to our PTCRManual “Technique & Application”.
Take control of your firing process
The accurate control of the firing/sintering process is ofhighest importance. After all, the results have a direct effect onthe quality and the costs of the final product.Optimal process control requires both, accurate measurementof the quantity of heat and the ability to control thetemperature and its uniform distribution throughout thekiln/furnace. Efficient process temperature measurement is akey to high product quality.
The Process Temperature Control Ring, PTCR, is a highly accurate ceramic temperature indicator which records the true heat treatment received by the fired product. PTCR rings take account of both radiated and transferred heat, as well as the effects of temperature over time. It conveniently allows this recorded heat exposure to be expressed as a single number - ring temperature (RT) - which is practical and easy to work with.
PTCR rings can be used in both batch and continuous tunnel kilns; they are used in a range of atmospheres.
covering a range from 560 to 1750°C.
Ring types are identified by color coding and batch and type numbers pressed into the ring.
PTCR rings are made from a mix of high-grade materials. Their composition is fine-tuned through advanced Design Of Experiments- (DOE), and the production process itself is controlled by Statistical Process Control.
In fact, the entire PTCR manufacturing facilities have been awarded the internationally recognized ISO 9001:2000 and ISO 14001 quality certification.
