Pyrometric Devices

Pyrometric Devices measure the amount of ‘Heat Work’ (the combined effect of both time and temperature) when firing materials within a kiln. In principle, a pyrometric device relates the amount of heat work on ware to a measurable shrinkage of a regular shape. Mantec specialises in the manufacture of the ‘industry standard’ pyrometric devices:

• Bullers Rings™
• Bullers Process Control Discs™

‘Bullers Rings’ are utilised by many of the world’s leading Tableware, Sanitaryware and Refractory manufacturers to measure the amount of ‘heat work’ that has taken place in the kiln, giving an independent, accurate, reliable and essential indication that the firing of the product is correct and unaffected by any variations in temperature and kiln loading. Bullers Process Control Discs™ have the same functionality and are especially designed for the growing quality assurance needs of the ceramic capacitor manufacturing industries.

Early notification of ‘under fired’ product allows you to re-fire product to the correct quality. This will save scrap product further down the process, which in turn maintains product capacity and profitability.
