美国ferro品牌测温环多种型号如zth uth eth lth sth mth hth等多个温区测温环，窑炉烧结后通过测量环的外径，比照测温环对照表，来测量窑炉温度。 摄氏度温度范围560-660度 660-900度 850-1100 970-1250 1130-1400 1340-1520 1450-1750型号。

7 types of PTCR rings are available: ZTH, UTH, ETH, LTH, STH, MTH, HTH covering a temperature range from 560 °C to 1750 °C. The rings are identifiable by a colour code assigned to them, as well as by a batch number engraved on each ring during pressing. Easy and accurate digital temperature measurement not subject to operator judgment.

När man tagit ut sin examen kan man skaffa en LTH-ring. Det finns en ring för civilingenjörsexamen, en för doktorsexamen och en för brandingenjörsexamen. Välkommen till Guldsmed Ingrid Trilk för att beställa er LTH-ingenjörsring.

PTCR (Process Temperature Control Rings) are used for verification of the thermal uniformity and reproducibility of heat work delivered by a specific heating profile. PTCR rings were originally designed for the electronics manufacturing industry but can also be used in Advanced and traditional Ceramic Industries.

Process temperature control rings PTCR decisively contribute to control and thus quality of thermal processes. With their special ceramic material properties, they determine the heat input more precisely than conventional measuring methods, and thus permit precise furnace settings.

There are seven diferent ring types, each in 3,5 mm (named L) and 7 mm thickness (named H) with an outer diameter of 20 mm and an inner diameter of 10 mm. They cover a temperature range from 560 to 1750 °C. The ring types are color …

The PTCR - Process Temperature Control Ring is a ceramic product that registers the actual heat treatment in kilns through contraction of its diameter. The PTCR takes account of both radiation and transfer heat as well as of the effects of temperature over time.

There are 7 types: ZTH, UTH, ETH, LTH, STH, MTH and HTH. The different types of rings can be recognised by their colour, the inscriptions engraved on them and their varying thickness. These different ranges allow the measurement of specific temperatures and are therefore adapted to the needs of particular areas.

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.

2021年11月27日 · First, you need to choose the right type for the temperature you want to fire. That is the pink PTCR-LTH ring if you fire above 1000 o C, but below 1250 o C. If you fire higher, take the green PTCR-STH ring that can be used up to 1400 o C (see also table below).
