K-Type Thermocouple | High-Temp Probe | 1300°C Kiln Sensor

This K-type thermocouple measures high heat, up to 1300°C. It's a specialized sensor for temperatures beyond what a standard pt100 can handle. You can use it in electric kilns, forges, and industrial muffle furnaces. Features and Benefits - Measures temperatures up to 1300°C - This lets you precisely watch processes like heat treating, smelting, and firing ceramics. - Ceramic and steel construction resists corrosion - It lasts a long time in harsh, hot environments. - Multiple probe lengths (150mm, 200mm, 250mm) - You can pick the right insertion depth for your equipment. - Includes a 1-meter shielded cable - This gives you enough length to connect the sensor to a PID controller or Arduino safely. Applications - Checking internal temperatures in pottery and glass kilns. - Managing heat for blacksmithing forges and metal casting. - Controlling industrial processes in ovens and furnaces. Safety & Preparation When working with high-temperature sensing equipment like this K-Type probe, safety is paramount. Always ensure power to the Muffle Furnace or Electric Kiln is disconnected before installation or inspection. The probe is designed for a temperature range of 0-1300°C, so extreme heat will be present during operation. Wear appropriate personal protective equipment, including heat-resistant gloves and eye protection. While this is a high-temperature K-Type probe, it is not specified as a semi-finished product, suggesting it is ready for installation. Ensure the probe length selected (150mm, 200mm, or 250mm) is suitable for your application. Identify standard RTD Values An RTD (Resistance Temperature Detector) sensor measures temperature by correlating resistance with temperature. While this specific product is a K-Type Thermocouple, understanding RTD principles can be helpful for general temperature sensing. RTDs typically use platinum, nickel, or copper wire, and their resistance changes predictably with temperature. The most common is the Pt100, which has a resistance of 100 ohms at 0°C. Other common values include Pt500 and Pt1000. These values are crucial for selecting the correct controller or display unit that can accurately interpret the sensor's output. How to Test by Wire Configuration To check an RTD sensor, understanding its wire configuration is essential. The number of wires affects how lead wire resistance is compensated for, which is critical for precision temperature measurement. A multimeter can be used to measure the resistance across the sensor's terminals. This product is a K-Type Thermocouple, not an RTD, so its testing method will differ, typically involving measuring voltage output. However, for general RTD sensors, the following wire configurations are common for checking functionality and accuracy with a suitable controller. A. 2-Wire RTD A 2-wire RTD is the simplest configuration, with two wires connecting the sensor to the measuring device or controller. One wire carries the current to the RTD element, and the other returns it. The resistance measured includes both the RTD element's resistance and the resistance of the lead wires. This can introduce inaccuracies, especially with long lead wires or in applications requiring high precision. To check a 2-wire RTD, measure the resistance across the two terminals. Compare this reading to the expected resistance value for the given temperature, often found on a datasheet. B. 3-Wire RTD (Most Common) The 3-wire RTD is the most common configuration for industrial applications due to its improved accuracy over 2-wire systems. It uses three wires: two for current flow and one for measuring the voltage drop across the RTD element. This third wire allows the measuring device or controller to compensate for the resistance of the lead wires. To check a 3-wire RTD, measure the resistance between the two current-carrying wires and then between one current-carrying wire and the voltage-sensing wire. The two lead wire resistances should be approximately equal, and the RTD element's resistance can be determined accurately.
