The sheath thermocouple type T is the first choice for precise temperature measurements in the low-temperature range. With its copper-constantan pairing, it achieves excellent measurement accuracy from minus 270°C to plus 400°C. Therma Thermofühler GmbH manufactures sheathed thermocouples type T for laboratory applications, refrigeration technology, and industrial processes that require maximum precision in the lower temperature range.
Type T thermocouples impress with their high homogeneity and low thermoelectric voltage drift. These properties make them particularly valuable for cryogenic applications and calibration purposes. Therma offers type T sheathed thermocouples in diameters from 0.25 mm to 6 mm and in customer-specific lengths. Our experience in manufacturing thermocouples since 1991 guarantees consistent quality and fast delivery, even for customized solutions.
The copper-constantan pairing of the Type T thermocouple offers decisive advantages at low temperatures. Copper as the positive conductor ensures high electrical conductivity and reproducible thermoelectric voltage. The EMF characteristic curve is particularly linear in the negative temperature range and enables measurement accuracies of less than one Kelvin.
Compared to other thermocouple types, Type T shows the lowest inhomogeneity of the thermocouple. This property is crucial for precision measurements in research and quality assurance. The basics of temperature measurement technology explain the physical relationships between the various thermocouples. Type T is particularly well suited for applications in humid environments, as the copper-constantan connection is less susceptible to corrosion than other alloys.
Therma offers Type T sheathed thermocouples in a wide range of diameters. For fast response times, thin sheaths with a diameter of 0.25 mm or more are recommended. These respond to temperature changes in milliseconds and are suitable for dynamic measurement tasks. Larger diameters up to 6 mm offer higher mechanical stability for installation in pipes or containers.
Select the sheath material to suit the application environment. Stainless steel 1.4301 covers most applications. Stainless steel 1.4571 is available for corrosive media. The measuring point can be insulated, grounded, or free. Insulated measuring points provide electrical separation from the sheath and prevent measurement loops. Grounded versions enable faster response times. We supply suitable thermocouple cables and compensation cables type T for transmitting the measurement signal.
Selecting the right sheath thermocouple type T depends on several factors.
The temperature range determines the choice of material for the sheath and insulation. The required response time influences the optimal diameter. Chemical resistance and mechanical requirements also play a role in the configuration. Therma supports you with technical advice on specifications. Our sales team is familiar with the requirements of the food industry, pharmaceuticals, and refrigeration technology. We also manufacture suitable solutions for research applications in cryogenics.
