Description
Unit KMeter-ISO is an integrated K-type thermocouple sensor unit that combines "acquisition + isolation + communication" functions. It uses the STM32F030 + MAX31855KASA 14-bit thermocouple digital conversion chip solution to achieve high-precision temperature acquisition and conversion. The MCU uses STM32F030 for data acquisition and I2C communication interface, and CA-IS3641HW is used as the signal isolator. This unit supports the connection of thermocouple probes with a measurement range of -200°C to 1350°C, and uses a universal standard K-type flat interface, making it easy to replace probes with different measurement ranges to meet various needs. This module is used in industrial automation, instrumentation, power electronics, heat treatment, and other fields for temperature acquisition, control, and monitoring applications.
