Product type
J-Type thermocouples are temperature sensors that consist of two different metal wires joined at one end. This junction produces a voltage that correlates to temperature differences, allowing for accurate temperature measurement. Typically made from iron and constantan, J-Type thermocouples are known for their reliability and quick response times, making them suitable for various applications in industrial settings.
| Temperature range | -40°C to 750°C |
| Accuracy | ±1.5°C or ±0.4% of reading |
| Wire diameter | 0.5 mm to 3.2 mm |
| Response time | Less than 1 second in still air |
| Insulation material | Fiberglass or ceramic |
When selecting a J-Type thermocouple, consider the temperature range and accuracy required for your application. Specify the wire diameter and insulation material based on the environment where the sensor will be used. It's also important to request information on calibration standards and certifications to ensure compliance with industry regulations. Quantities may vary depending on the scale of your project, so provide estimated needs when requesting quotes.
