RS PRO IEC Type K & Type T Exposed Single Shot Thermocouple and Miniature Plug_x000D_ Introducing the range of RS PRO Type J, K and Type T single shot temperature sensing thermocouples that conform to IEC-584-3 standards with a Class 1 tolerance for optimum performance. These Type K and Type T single shot temperature sensors have a durable Teflon PTFE insulated class 1 single cable construction 1/0.37 mm lead. The lead is terminated with a rewireable miniature flat pin plug for a quick and easy connection. These thermocouples have an exposed junction which enables them to operate with a fast response time._x000D_ Features and Benefits:_x000D_ IEC-584-3 class 1 tolerance for optimum accuracy_x000D_ Miniature plug for quick and easy connection_x000D_ Exposed junction for fast response_x000D_ Durable Teflon PTFE insulation for resistance to oils, acids and fluids and good mechanical strength and flexibility_x000D_ Single shot cable construction offers gas, steam and watertight insulation, making it suitable for use in autoclave and aerospace applications_x000D_ Temperature range from -75 to +250°C_x000D_ Applications:_x000D_ These Type K and Type T thermocouple temperature sensors are ideal for test and development applications including:_x000D_ Test and measurement_x000D_ Temperature mapping_x000D_ OEM applications_x000D_ How does a Thermocouple Work?_x000D_ 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 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 which is a process also known as the Seebeck Effect._x000D_ What is a Welded Exposed Junction?_x000D_ An exposed junction is where the thermocouple wires are welded together but 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_x000D_ Why RS PRO?_x000D_ RS PRO is our own brand range and brings you a wide range of high-quality, great value products offering you more choice.
