RS Pro IEC Type K Magnet Housing Thermocouple with Miniature Plug

From RS Pro an IEC standard Type K thermocouple temperature sensor designed for taking rapid and reliable surface temperature measurements. This thermocouple sensor has a rugged design with a 2 m long durable steel over-braided PFA Telfon insulated lead. One end of the lead is terminated with a miniature plug and the other with a strong 1 inch diameter magnet housing for attaching to ferrous metal surfaces. The thermocouple junction is grounded for a fast response time.

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. In surface temperature sensing thermocouples the exposed welded wire junction is housed in a magnet or adhesive patch which provides 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
• Grounded thermocouple tip for fast response time
• Strong magnet housing with a 3kg pull for attachment on metal surface
• Miniature plug (200°) for quick and easy connection
• Durable PTFE insulated leads with stainless steel braid
• Sensor temperature range of up to -50 to + 250°C

Applications

K-Type surface thermocouples (Nickel-Chromium / Nickel-Alumel) are the most common type of thermocouple and are both accurate and flexible and reliable with a wide temperature range. This K-type magnetic thermocouple is ideal for use in permanent or temporary ferrous metal temperature monitoring applications especially test and development. Other applications include HVAC, air conditioning, plumbing and temperature mapping
