MAX31850K Thermocouple Amplifier Breakout 1-Wire K-type

Precision Temperature Monitoring with Versatile 1-Wire Connectivity: Enhance Industrial and Scientific Measurement Systems with the 7Semi MAX31850K Thermocouple Amplifier

The 7Semi MAX31850K K-type Thermocouple Amplifier Breakout is a high-precision temperature sensing module engineered for demanding applications that require reliable, high-resolution thermal monitoring. Designed with the robust MAX31850K thermocouple-to-digital converter, this module provides accurate temperature data by integrating cold-junction compensation and 14-bit resolution signal digitisation. It outputs precise readings in 0.25°C increments, covering an ultra-wide temperature range from -270°C to +1370°C, which makes it an ideal choice for industrial control systems, scientific experiments, HVAC systems, and thermal profiling setups.

Built to support K-type thermocouples via a convenient 1-Wire digital interface, the module allows multiple sensors to share a single data line. This minimises wiring complexity and supports scalable sensor networks, particularly useful in automation and data acquisition systems. The breakout board also features onboard protection circuits, including open thermocouple detection and short-circuit protection, ensuring reliable long-term operation even in harsh environments. The module comes pre-soldered with essential components including a 2-pin terminal block, pullup resistor, and pin header for fast and hassle-free integration into existing setups.
