Sheathed thermocouple type N for precise high-temperature measurement
The sheathed thermocouple type N has established itself as a reliable solution for demanding temperature measurements in the high-temperature range. With its Nicrosil-Nisil pairing, it offers excellent long-term stability and resistance to oxidation at temperatures up to 1200°C. Therma Thermofühler GmbH manufactures Type N sheathed thermocouples in various designs for industrial applications, research facilities, and laboratory environments.
Type N sheathed thermocouples are characterized by lower thermoelectric voltage drift than comparable Type K sensors. This property makes them particularly valuable for long-term measurements and applications that require maximum accuracy over an extended period of time. Therma offers type N sheathed thermocouples in diameters from 0.25 mm to 6 mm and in customer-specific lengths. As a manufacturer with experience since 1991, we can advise you on selecting the right specification for your measurement task.
Type N sheathed thermocouples for demanding measurement tasks
Type N sheathed thermocouples prove their worth wherever other thermocouple types reach their limits. The Nicrosil-Nisil alloy shows significantly higher resistance to corrosion and oxidation than the NiCr-Ni pairing of type K. Especially in oxidizing atmospheres and with cyclic temperature changes, the type N thermocouple retains its measuring accuracy.
The temperature range from minus 270°C to plus 1300°C opens up a wide range of possible applications. The EMF characteristic curve of type N is almost linear and enables precise measurements over the entire range. For customized solutions, Therma manufactures sheathed thermocouples with different sheath materials. Stainless steel 1.4841, Inconel 600, or Nicrobell are available depending on the application environment. The choice of sheath material influences the chemical resistance and maximum operating temperature of the finished sensor.
Areas of application for type N sheathed thermocouples in industry and research
The Type N sheathed thermocouple has become the standard in heat treatment and furnace processes. Its high stability at temperatures above 1000°C makes it the first choice for hardening shops, annealing furnaces, and melting processes. Type N thermocouples are also used in the glass industry and ceramics manufacturing, where they measure reliably under extreme conditions.
Research institutions and universities appreciate the reproducibility of the measurement results. In long-term tests and material testing, Type N sheathed thermocouples deliver constant values without significant drift. The basics of temperature measurement technology explain the physical background of the various thermocouple types. In petrochemicals and power plant processes, type N sensors prove their worth through their resistance to sulfur-containing atmospheres. Unlike type K, they show no conversion effects in the critical temperature range between 300°C and 500°C.
Order type N sheathed thermocouples in various designs
Therma offers type N sheathed thermocouples in all common configurations. You can choose between insulated, grounded, or free measuring points depending on your requirements for response time and electrical insulation. The sheath diameter determines the mechanical stability and response behavior. Thinner sheaths react more quickly to temperature changes, while thicker ones offer greater bending stiffness.
We manufacture the length according to your specifications. Whether standard lengths or special dimensions, our production facility in Germany will precisely meet your requirements. For signal transmission, we recommend suitable thermocouple cables and compensation cables of type N. These ensure error-free transmission of the thermocouple voltage to the evaluation electronics. If you have any questions about configuration, our technical sales team will be happy to assist you with personal advice.
