RS PRO Type K Thermocouple 40mm Length, 1/0.2mm Diameter → +150°C, Термопара

RS Pro IEC Type K Silicone Patch Thermocouple with Miniature Plug

From RS Pro an IEC standard Type K thermocouple temperature sensor designed for taking surface temperature measurements. The thermocouple lead is made from a 1 m length of twin-twist wire with a durable PFA insulation. One end of the lead is terminated with a miniature plug for a quick and easy connection. The other end is terminated with a 40 x 15 mm aluminium foil backed self adhesive moulded silicone patch for attaching to a surface.

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 Surface Thermocouple?

This thermocouple is designed for measuring the temperature on a surface. Most thermocouples have a sensing tip where there ends of the thermocouple wires are encased in sheaths or protection tubes which do not allow for measuring the temperature of a surface area. Surface temperature sensing thermocouples overcome this problem by having the exposed welded wire junction housed in a magnet or adhesive patch. The patch or magnet is then securely attached to the surface to be measured to provide a true surface contact. This affixing method allows these thermocouples to be used on many types of surfaces including uneven and circular surfaces. They are also simple to use and easy to replace and position.

Features and Benefits

• Conforms to IEC standards
• Self adhesive silicone patch for accurate surface sensing
• Miniature plug for quick and easy connection
• Durable PFA insulated leads for resistance to oils, acids, fluids and for good mechanical strength and flexibility

Applications

Type K Thermocouples (Nickel-Chromium / Nickel-Aluminium) are the most common type of thermocouple and are both accurate and flexible with a wide temperature range. Typical applications for these mineral insulated Type-K thermocouple probes include heat exchangers, power stations, brick and cement kilns, heat treatment and annealing furnaces, thermostats, food thermometers, vehicle diagnostics and in laboratories
