描述

數字 I2C K型 高溫感測器模組 Gravity I2C High Temperature Sensor (K-Type, 800℃)   DFRobot 原裝進口 支援 Arduino 與 樹莓派 開發版

數字 I2C K型 高溫感測器模組 Gravity I2C High Temperature Sensor 由信號放大轉換模塊和鎧裝K型熱電偶探頭組成，當K型熱電偶探頭置於高溫熱源時，探頭兩端由於熱電效應產生一個與溫度呈正比的微弱電壓，信號放大轉換模塊採用MAX31855K專用芯片將這個微弱的電壓信號進行放大、模數轉換與相應補償，最終通過 Gravity I2C 接口向主控器發送探頭的測量溫度。信號放大轉換模塊最大可測量極寬的溫度範圍-270℃~1372℃，在-200℃~700℃誤差不超過±2℃，700℃~1350℃誤差不超過±4℃，配套的鎧裝K型熱電偶探頭測溫可達800℃，在量程範圍內誤差不大於±2.5℃，能夠滿足大部分400度以上超高溫度的測量場景。

PT100適用於大部分400℃以下高溫的測量，但是通常家用天然氣灶焰芯溫度可達800℃以上，燒製陶瓷的窖子或者大功率電爐溫度更可超過1000℃，在這些超高溫度的場景下就需要用到K型熱電偶。

Gravity: Digital High Temperature Sensor (K-type)

Introduction

PT100 is suitable for most of the temperature measurement below 400°C, but usually the temperature of the household natural gas stove can reach over 800°C, and the temperature of the pottery kiln or high-power electric furnace can be more than 1000°C. The K-type thermocouple are commonly used in such ultra-high temperature scenes.

The digital K-type high temperature sensor consists of a signal amplification conversion module and a sheathed K-type thermocouple probe. When the K-type thermocouple probe is placed near a high-temperature heat source, the probe generates a small voltage proportional to the temperature due to the thermoelectric effect. The module uses a MAX31855K dedicated chip to amplify this small voltage, convert it to digital signals, and compensate accordingly. The temperature readings can be read through Gravity I2C interface. The module can measure extremely wide temperature ranging from -270°C to 1372°C, the error from -200°C to 700°C is within ±2°C, and the error from 700°C to 1350°C is within ±4°C. The attached K-type thermocouple can measure up to 800 °C with error within ± 2.5 °C.
