We having specialization to manufacture all critical Thermocouples for different applications in Glass Industries

Thermocouples for Furnace Crown
It is well known that Glass Melting Furnace includes a melting chamber in which solid batch materials are heated to produce molten glass. The arch of this melting chamber is known as crown. To measure and control the temperature of furnace crown is important, because with the correct temperatures one can improve the service life of crown, as the overheating of the crown may cause of early erosion of crown refractory and the other side if the temperatures are low, it can affect the melting efficiency and will increase the fuel consumption. The highest temperature in melting furnace is at crown. To select the right materials and assembly is important as the temperature at crown is even more than 1600°C. The design we recommend is with dual protection sheaths. In most of the furnace thermocouples are placed in block pockets, but over a period of service it may get through hole. At crown there are number of points to measure in center, Right & Left, the same kind of assemblies can be used for Regenerator Crown as well.

Thermocouples for Furnace Bottom
Same as crown, to measure the correct temperatures at furnace bottom result for higher service life of bottom blocks. Bottom blocks are the costliest part of a melting tank. Bottom thermocouples are used to get efficient operation of Glass Furnace. Even 2 - 3 Degrees higher or lower temperature can affect the fuel consumption of furnace. On this application hole can be through to immerse a glass immersion thermocouple, which will be with hardened platinum / platinum alloy thimbles over ceramic protection tubes. If the hole is blind or thermocouple pocket, the protection will be with recrystallised alumina protection sheaths.

Trilevel For Forehearth/Distributor
In Distributor & Fore-Hearths temperature measurement & control is most important, the glass fore-hearth control system includes a temperature sensing system and control system. The temperature sensing system includes an arrangement of pre-positioned temperature sensors. Simplex thimble thermocouples & tri-level / triplex thermocouples consist of an assembly of a bottom, middle and top thermocouples for sensing the vertical temperature profile of the molten glass at a fixed location. The output signals from these temperature sensors are received by controllers of the control system which then provide control signals & regulate the operation of the heat input devices and the cooling input devices. Thermocouple output & controller's calibration must be accurate, reliable and repeatable.
The Tri-Level Thermocouples designed to achieve thermal homogeneity of the glass exiting from the fore-hearth for forming, as the homogeneity will help to get the proper distribution of Gob in moulds.

Simplex Forehearth/Distributor
In Distributor & in Fore-Hearths rear and middle zone most of the glass companies use this simplex small thimble thermocouple. This is the substitute of fibre optic pyrometer. With Pyrometer customer can get only glass surface temperature but using this thermocouple, customer can get glass immersion temperatures. It is commonly used in all container glass industries. When conditioning zone trilevels & rear /Middle zone simplex Thermocouple are manufactured with same batch element, Customer can get relative temperatures.

Blank Mould Thermocouples
To measure the temperature at Blank Mould is important ,to achieve proper job distribution & product quality. Most of the container glass industries are using Blank Mould 'K'Type Thermocouple / J type with mineral insulating flexible high temperature cable. These Thermocouples are lower in dia i.e. 1.5mm /3 mm, and as it is flexible it can be used for different size of moulds. These Thermocouples will help to get continuous monitoring of mould temperature.

Spout Thermocouples
In container glass industries Spout Bowl glass temperature is very important .To measure it, we designed Spout Bowl Thermocouples in nobel metal with platinum thimble. It is immersed through side and user can get correct temperature of molten glass just before glass cutting. Length as per application need.
