Components Sheathed thermocouples for high-temperatures have improved vibration resistance
The devices are said to resist hotter environs better than conventional thermocouples.
Türk+Hillinger’s thermocouples are high-tech sensors with fast response, extreme accuracy and are also easily bendable, the company said. Türk+Hillinger has improved the connection technology to make the thermocouples, which are embedded in a stainless steel casing with highly compressed magnesium oxide as an insulator, to withstand a much higher temperature resistance than conventional thermocouples. According to the company, this was achieved with newly developed insulation materials that increase the thermal stability of the connection up to 500C, while also ensuring maximum moisture protection.
In addition, the company has miniaturised the connection sleeve. The thermocouples are smaller and more robust than other thermocouples available on the market, which is a major advantage to hot runner manufacturers, the company said. It added that this new connection ensures that the movements, shocks, and vibrations from the outside are no longer transferred to the inside of the contact points. The end-user is said to benefit from increased process safety because of the extremely high mechanical strength, combined with the high pull-out strength of the thermocouple, as well as the leads from the casing.
The thermocouples are available from 1.0 mm diameters and can be assembled with the required lead length upon the customer’s request. The measuring point of the thermocouple is selectively connected to the casing or, alternatively, insulated from the jacket, according to the supplier.
Furthermore, as part of its sensor product portfolio, Türk+Hillinger can also provide sheathed platinum resistors PT100 / PT1000 and coated NTC resistors in various lengths and diameters.
