RS PRO Heavy Duty Thermocouple Type K

Thermocouple type: K
Probe diameter: 4.5 mm
Probe length: 150 mm
Sensor material: Stainless steel
Connection type: Common connector
Cable length: 2 m
Standards met: IEC

This rugged design features thermocouples of type J and K, which are devices for temperature measurement consisting of two wires made of different materials. When these wires are connected, they form an electrical connection. A change in temperature at this connection generates a voltage that can be used to read the temperature, commonly referred to as the Seebeck effect.

Features and benefits include a 316 stainless steel probe with a silver soldered tip, measuring Ø 4.5 mm x 150 mm. It is optionally available with bare lead wire or standard connector termination with cable clamps. The cable is 2 m long, with a 7/0.2 mm configuration, featuring fiberglass insulation and a stainless steel braid. The product comes with a three-year warranty and has a grounded measuring point. It operates within a temperature range of -60 to +350 °C.

Types of thermocouples:

• Type K thermocouples are among the most common due to their low cost, high accuracy, reliability, and wide temperature range.
• Type J thermocouples are also widely used, known for their low cost, good performance, and high reliability, though they may have a shorter lifespan in higher temperature ranges.
• Type T thermocouples offer stability and consistency, typically used in exceptionally low temperatures, such as freezing.
• Type N thermocouples have similar accuracy and temperature limits as Type K but are slightly more expensive.
• Type L thermocouples specialize in measuring liquids, such as liquid metals, and are often used in heating and apparatus engineering. They are inexpensive, efficient, and reliable.
