Pyrometric Devices

Pyrometric Devices measure the amount of ‘Heat Work’ when firing ceramic products within a kiln.  Heat Work is the action and effect of temperature over time on a product, often referred to as Heat Energy . A pyrometric device will make the same 'thermal journey' as the ceramic product being fired and its shrinkage is a key indicator of consistent  and optimal firings. Mantec Technical Ceramics Ltd specialises in the manufacture of the following ‘industry standard’ pyrometric devices:

Bullers™ Rings

Bullers™ Process Control Discs

Bullers™ Rings and Bullers™ Process Control Discs (BPCDs) allow you to understand the effect that variations in temperature, rate of firing and length of soaking time have on the product and what action is required to prevent costly production problems occurring on future firings.

They can be used to increase your yields and early notification of under–fired products allow you to re–fire to the correct quality, saving scrap products while maintaining capacity and profitability. Only Heat Work measuring and monitoring using our Pyrometric Devices will allow you to understand what has happened to the product in the kiln independently of time and temperature.

Bullers™ Rings and Bullers™ Process Control Discs (BPCDs) are therefore an essential part of any Quality Assurance system involving the firing of ceramic products.
