RS Pro Glassfibre IEC Exposed Welded Tip Thermocouples
From RS Pro a range of Type J, K, T & N wire type thermocouple temperature sensors conforming to IEC 60584 standards. These thermocouples have a welded exposed hot junction for a fast response time and cable conductors surrounded by a glassfibre insulation.
How does a Thermocouple Work?
A thermocouple is a sensor used to measure temperature in a range of different processes and consists of two wire legs made from different metals joined together at their two ends to form two junctions. The hot, or measuring junction is connected to the body whose temperature is going to be measured. The cold junction or reference junction is connected to a body of known temperature. When the measuring junction is placed on something hot a voltage or potential difference between this and the reference junction occurs. This voltage can then be converted into a temperature measurement using thermocouple reference tables. This process is also known as the Seebeck Effect
What is a Welded Exposed Junction?
An exposed junction is where the thermocouple wires are welded together but are not surrounded by the outer sheath. The ends of the wire are directly inserted into the process. This means the thermocouple has a high sensitivity and response time. Welded exposed junctions are more prone to corrosion and are recommended for measuring flowing or static non-corrosive gas temperatures
Properties of Glassfibre Insulation
Glassfibre wire insulation is flexible with a good temperature range but does not prevent the ingress of fluids
Key Features and Benefits
• Welded, exposed junction for fast response times
• Glassfibre insulated cable for good flexibility and temperature range
• Conforms to IEC 60584 standards
Applications
These grounded junction Type J, K, T & N wire thermocouples are ideal for test and development applications including test and measurement, temperature mapping and OEM applications
