Description

KMeterISO unitis an integrated K-type thermocouple sensor unit that integrates the functions of "acquisition + isolation + communication", using STM32F030+MAX31855KASA+T 14bit thermocouple digital conversion chip scheme to achieve high-precision temperature acquisition and conversion, MCU using STM32F030 to realize data acquisition and I2C communication interface, using CA-IS3641HW as a signal isolator. The unit supports access to thermocouple probes with a measurement range of -200°C to 1350°C, and adopts a universal standard K-type flat interface, which is convenient for subsequent replacement of different measuring probes to match different needs. This module is widely used in application scenarios such as temperature collection, control, and monitoring in industrial automation, instrumentation, power and electrical, heat treatment and other fields.
