FAQs
1. What is an Industrial Type K Thermocouple and how does it work?
An Industrial Type K Thermocouple is a temperature sensor made from two dissimilar thermoelectric alloys: Chromel (Nickel-Chromium) and Alumel (Nickel-Aluminium). These conductors are joined at a sensing junction. When the junction experiences a temperature difference relative to the reference junction, it generates a small thermoelectric voltage through the Seebeck effect. A compatible temperature indicator, controller, transmitter, scanner, or data acquisition system measures this signal and converts it into a temperature reading.
2. Why choose a Duplex Thermocouple over a Simplex model?
A Duplex Thermocouple contains two independent thermocouple elements within a single protective sheath. This allows one sensing circuit to provide temperature feedback to a PLC, DCS, or process controller, while the second circuit can be connected to an independent safety alarm, indicator, recorder, or monitoring system. This arrangement provides measurement redundancy without requiring a second process penetration or separate thermocouple assembly.
3. What is the maximum operating temperature for an SS310 Thermocouple Sheath?
SS310 stainless steel is a high-temperature-resistant sheath material offering excellent resistance to thermal oxidation and high-temperature corrosion. For thermocouple applications, the practical maximum temperature depends on the sheath construction, atmosphere, thermocouple element, exposure time, and installation conditions. An SS310 sheath can commonly be used for continuous service around 850°C, with the actual permissible temperature determined by the complete sensor assembly and application conditions.
4. Is the insertion depth of the Aavad AKWD-10D8 Thermocouple adjustable?
Yes. The Aavad AKWD-10D8 Type K Thermocouple is supplied with a 1/2" Male BSP adjustable process connection, allowing the effective insertion depth of the probe to be positioned according to the installation requirements. This makes it suitable for temperature measurement in ducts, pipelines, tanks, vessels, and industrial process equipment where installation depth needs to be adjusted on site.
