These insulated wire thermocouples are one of our most popular styles for general purpose use. They are supplied in packs of 5 and there are 4 different models featured on this page:
5SRTC with a miniature size thermocouple plug and strain relief for the thermocouple wire.
5SC has a miniature size thermocouple plug with an integral wire caddy for storage of the thermocouple wire.
5LRTC with a standard size thermocouple plug and strain relief for the thermocouple wire.
5LSC has a standard size thermocouple plug with an integral wire caddy for storage of the thermocouple wire.
All models are available with 90 cm or 1,8 metre wire lengths and 3 types of wire insulation: Kapton and PFA provide good protection against moisture and abrasion resistance and are rated for maximum service temperatures of 315°C and 260°C respectively providing at the same time a fast response to temperature changes. Glass Braid is rated for a maximum service temperature of 480°C. Wire diameters of 0.08, 0.13, 0.25, 0.5 and 0.8mm are available. The smaller diameters have a faster response time whilst the large diameters are more durable.

Thermocouple Sensor / What is a Thermocouple?
A thermocouple is a sensor for measuring temperature. This sensor consists of two dissimilar metal wires, joined at one end, and connected to a thermocouple thermometer or other thermocouple-capable device at the other end. When properly configured, thermocouples can provide temperature measurements over wide range of temperatures.
Thermocouples are known for their versatility as temperature sensors therefore commonly used on a wide range of applications...

How is Temperature Measured?
Temperature can be measured via a diverse array of sensors. All of them infer temperature by sensing some change in a physical characteristic. Six types with which the engineer is likely to come into contact are: thermocouples, resistive temperature devices (RTDs Pt100 and thermistors), infrared radiators, bimetallic devices, liquid expansion devices, and change-of-state devices.
Choose the right temperature measurement instrument for your application...

What is a Type K Thermocouple?
A Type K thermocouple refers to any temperature sensor containing Chromel and Alumel conductors, that meets the output requirements as stated in ANSI/ASTM E230 or IEC 60584 for Type K thermocouples. This may be an immersion sensor, a surface sensor, wire or another style of sensor or cable.
Type K wire is primarily available in two color-codes, yellow connectors and/or yellow and red conductors per ANSI/ASTM E230, or green Connector and/or green and white conductors per IEC 60584.

What Are Common Applications for Thermocouples?
Thermocouples are the most widely used temperature sensors on the planet due to their combination of wide temperature capabilities, ruggedness, and low cost. Thermocouples are used in applications that range from home appliances to industrial processes, to electric power generation, to furnace monitoring and control, to food and beverage processing, to automotive sensors, to aircraft engines, to rockets, satellites and spacecraft.
When it comes to high temperatures, small size, fast response, high vibration or shock, most times you will find thermocouples providing the temperature measurements.

Common Techniques to Calibrate Thermocouples
Temperature measurement is possible through several means. We commonly use thermometers for measuring temperature. However, for precision measurements, where even a small spike in temperature requires to be recorded, we use advanced forms of measurement devices like thermocouples. Thermocouples are measurement devices that can read very slight temperature changes. Hence, they are widely used in applications where accuracy is of utmost importance.
However, like any measurement device, the efficiency of thermocouples will deteriorate overtime under constant use. At this point, the thermocouple needs recalibration...
